2 FIRST AID FOR ELECTRICAL SHOCK AND SAFETY RULES

2.1 FIRST AID FOR ELECTRICAL SHOCK

Do not touch the bare hands until the circuit has been opened. pen the circuit by switching off the lineswitches. If that is not possible protect yourself with dry material and free the patient from the con-ductor.

2.1.1 Artificial respiration

It is important to start mouth resuscitation at once and to call a doctor immediately. suggested procedurefor mouth to mouth resuscitation method is described in the Tab.1.

2.1.2 Treatment of burns

This treatment should be used after the patient has regained consciousness. It can also be employed whileartificial respiration is being applied (in this case there should be at least two persons present).

Warning

• Do not attempt to remove clothing from burnt sections

• Apply dry gauze on the burns

• Do not apply ointments or other oily substances.

MN.00273.E - 004 9

Tab.1 - Artificial respiration

Step Description Figure

1

Lay the patient on his back with his arms parallel to the body. If the patient is laying on an inclined plane, make sure that his

stomach is slightly lower than his chest. Open the patients mouth and check that there is no foreign matter in mouth (den-

tures, chewing gum, etc.).

2

Kneel beside the patient level with his head. Put an hand under the patient’s head and one under his neck.

Lift the patient’s head and let it recline backwards as far as possible.

3

Shift the hand from the patient’s neck to his chin and his mouth, the index along his jawbone, and keep the other fingers

closed together.

While performing these operations take a good supply of oxy-gen by taking deep breaths with your mouth open

4

With your thumb between the patient’s chin and mouth keep his lips together and blow into his nasal cavities

5

While performing these operations observe if the patient’s chest rises. If not it is possible that his nose is blocked: in that case open the patient’s mouth as much as possible by pressing on his chin with your hand, place your lips around his mouth and blow into his oral cavity. Observe if the patient’s chest heaves. This second method can be used instead of the first even when the patient’s nose is not obstructed, provided his

nose is kept closed by pressing the nostrils together using the hand you were holding his head with. The patient’s head must

be kept sloping backwards as much as possible.

6

Start with ten rapid expirations, hence continue at a rate of twelve/fifteen expirations per minute. Go on like this until the patient has regained conscious–ness, or until a doctor has as-

certained his death.

7.1.2 Baseband processor

The baseband Processor (BBP) carries out the following operations:

• primary and secondary power supply

• line interfaces and protections

• baseband circuits and packets processing

• I and Q signals generation and sampling

• I, Q demodulator

• Rx baseband filtering

• Actuators and measurement points for TRx unit

• FPGA debug connector

• FPGA

• Controller

BBP unit is different depending on the interface type (electrical or optical).

7.1.2.1 Firmware

Equipment software permits to control and manage all the equipment functionality and it is distributed ontwo hardware levels: main controller and ODU peripheral controllers.

Firmware can be updated through the Web Lct and it is stored in two different memory benches: one con-taining the running firmware and the other the stand-by firmware. This permits to download a new firm-ware release to the stand-by bench without cutting the traffic. Use “Bench Switch” to activate the benchin stand-by (SW restart will be performed).

7.1.2.2 Web Lct

The Web Lct is a web interface software already present in the ALFOPlus, which requires Adobe Flash Playerand allows the configuration and the management of the local radio, using LAN Port Management. Whenthe remote one is configured properly, the whole link can be managed. WEB Lct runs on any browser (In-ternet Explorer, Firefox etc....). Web Lct console is a free software downloadable from the site www.siae-mic.com after registration.

In order to transfer data, “WebLCT console” or “SCT” running is necessary.

7.1.2.3 Alarm system

There are two ways of processing the alarms:

• through LEDs

• through SCT/WebLCT

Alarm associated to ALFOplus can be classified in different groups. Names and composition of these groupsas well as association between alarm classes and relay contact can be defined by the customer.Alarms are divided into 4 severity levels according to the effects that an alarm might cause to the regularoperation of the unit detecting it. Levels are prioritised as follows:

• Critical (red): out-of-service. hw failure. urgent alarm

• Major (orange): loss of signal, minimum residual functionality, urgent alarm

• minor (yellow): failure neither urgent, high residual functionality, not urgent alarm

• warning (light blue): indication or wrong configuration, not urgent alarm

• none (green): no alarm or masked alarm

56 MN.00273.E - 004

Critical and Major alarms indicate impossibility of executing a service, hence the faulty units needs to beserviced. Minor level represents the not urgent alarms which do not prejudice service continuity. Warninglevel indicates malfunctions that might be locally removed without having to replace the unit.

Alarm classification can be modified via SCT/WebLCT operator. A short description is given for each alarmin “Alarms” section with relevant class.

The visual indication is given by a LED, which can be green or red. The information provided are:

• Red light:

- ON - An internal alarm is active. Connect the PC for troubleshooting

- Flashing - An external alarm is active

• Green light:

- Flashing - No radio connection with far-end terminal

- ON - Radio connection with far-end terminal is active

During the power-up follows three status of display Led (see Tab.19)

Tab.19 - bootstrap status display

7.1.3 TRX Transceiver unit

TRX Transceiver consists of the following functional blocks:

• power supply dedicated to microwave circuits

• Tx baseband filtering

• I, Q modulator

• frequency synthesizer

• microwave transmitter and receiver

• IF devices on Rx side

7.1.4 Switch for Ethernet ports

Inside ALFOplus is present an Ethernet switch with 2 external ports line side (electrical 10/100/1000BaseTor optical 100/1000BaseFX), one internal radio port and one port towards controller (see Fig.16).

Internal port is represented by the local radio stream where through native Ethernet transport is connectedwith the remote equipment.

MN.00273.E - 004 57

Fig.16 - ALFOplus block diagram

Switch function

ALFOplus can operate like a switch between two or more separated LANs with the following advantages:

• to connect two separate LANs

• to connect two LANs via radio within a complex digital network

• to keep separated the traffic into two LANs towards MAC filtering to get a total traffic greater thanthe traffic in a single LAN.

By default the routing works on basis Mac Address (Layer 2), but it can be enabled on basis VLAN ID, inWeb Lct - Ethernet switch (Enh) - Common Parameters.

The operation is the following: when a LAN port receives a MAC frame, on the basis of destination address,it decides which LAN to send it:

• if destination address is on originating LAN the frame is discarded

• if destination address is a known address (towards address learning procedure) and is present intolocal address table, the frame is sent only on destination LAN (MAC switching)

• otherwise the frame is sent to all ports with the same VLAN ID (flooding).

Take account the value of Max Packet Size (byte) when “802.1Q setting” is set as DISABLE or FALLBACKthe switch adds 4 Bytes for internal S_Tag. With 802.1Q setting in SECURE (that means that packet VIDmust be contained in Virtual LAN table list, otherwise the packet is discarded), no internal TAGs are added.

Ethernet Speed/Duplex function

With electrical interface, in Web Lct - Baseband - Lan, Speed/Duplex can be manually or automaticallyactivated as half Duplex or Full Duplex 10/100/1000Base-T, while with optical interface, Speed Duplex canbe set as Full Duplex 100/1000Base-X.

Link Loss Forwarding

Link Loss Forwarding (LLF) is an alarm status of Ethernet interface. LLF can be enabled or disabled.

If LLF is enabled, any linkdown alarm will generate the alarm status of Ethernet interface blocking anytransmission to it. LLF can be enabled for each ports.

With LLF enabled the equipment connected (routers, switches so on) can be notified that radio link is notavailable and can temporarily re-route the traffic.

MDI/MDIX cross-over

For each LAN interface, cross-over cable can be set in Web Lct - Baseband - Lan - Cable Crossover as:

• Auto - Lan recognizes automatically the connected cable type (Straight cable or Crossover cable)

• MDI (NIC) - Manual crossover wiring type T568A

• MDI-X (Switch) - Manual crossover wiring type T568B

With crossover cable it is necessary to use the same wiring format (MDI/MDI or MDI-x/MDI-x) on bothends. In case of straight cable is the opposite (MDI/MDI-X or MDI-X/MDI).

VLAN functionality

ALFOplus works with IEEE 802.1q and 802.1p tag. Tag is made up with:

• a fixed word of 2 bytes

• 3 bits for priority according with 802.1p

• 1 fixed bit

• 12 bits VLAN identifier (VLAN ID) according with 802.1q.

Switch cross-connections are based on Vlan Configuration Table where input and output ports or only out-put ports should be defined for any used VID. Vlan ID (VID) has a range from 1 to 4095.

Ethernet Flow Control (802.3x)

A network device asks its adjacent devices to send a pause frame because the input is faster it can process.The protocol used for this purpose is the flow control (802.2x).

Port Based VLan

Port Based VLan (or Lan Per Port) allows to share the Ethernet traffic (Ingress or Egress) in the internalSIAE switch.

7.1.5 Synchronisation

Into ALFOplus a synchronisation circuit, called SincE and defined by the standard G.8264, gets the syn-chronisation signal from the following different sources:

• LAN1

• LAN2

• radio

• Internal source

As shown in Fig.17 the clocks extracted from the sources are sent to a selection circuit that chooses oneof the signals depending on the control sent by a selection logic.

This latter acts on the base of alarm roots (Synch Loss, Synch Drift, Holdover Freerunning), on the baseof assigned priority, manual forcing and preferential switch.

The selected clock drives an oscillator through a PLL circuit. The oscillator will generate the required syn-chronisation for the frame generation. If no input signals are available the internal oscillator source is usedfor the local restart.

7.1.6 Adaptive code modulation

ACM profiles

In ALFOplus radio family uses Adaptive Code and Modulation (ACM) in order to employ the correct modu-lation profile depending on the Rx signal quality.

Available ACM profiles are the following:

• 4QAM strong

• 4QAM

• 16QAM strong

• 16QAM

• 32QAM

• 64QAM

• 128QAM

• 256QAM

• 512QAM

• 1024QAM (optional).

These profiles operate in an RF channel with the following bandwidth:

• 7 MHz

• 14 MHz

• 28 MHz

• 56 MHz

• 112 MHz (optional).

ACM switching

The usage of the previous modulation profiles in a fixed channel bandwidth results in a variable capacity.The criteria defining the necessity of an ACM switching, upshift or downshift, is the Rx S/N ratio.

• Upshift - When there is an increase of received S/N, within the same Channel Spacing, the modu-lation complexity is increased in the direction from 4QAM strong to 1024QAM increasing the spectralefficiency

• Downshift - When there is a decrease of received S/N, within the same Channel Spacing, the mod-ulation is reduced in the direction from 1024QAM to 4QAM strong reducing the spectral efficiency,

In order to configure properly the radio link using ACM facility, an optimization must be found betweenmax traffic during good propagation conditions and max availability during bad propagation conditions. Toobtain this purpose the ACM in ALFOplus family can be configured via software setting the following pa-rameters: ACM setting and Tx Power mode.

ACM setting

The ACM can vary modulation profiles between two extremes defined by the operator through softwareconfiguration: Upper Modulation and Lower Modulation.

• Upper modulation - When propagation into the given radio channel is in the better condition (highRx S/N), the radio link is working at the maximum throughput defined at Upper Modulation: thehighest modulation profile that ACM can employ

• Lower modulation - When propagation into the given radio channel is in the worst condition (lowRx S/N), the radio link is working at the minimum throughput, defined at Lower Modulation: thelowest modulation profile that ACM can employ

Tx Power Ramp

Tx Power Ramp function permits to set Tx power according to the available modulation profiles.

• Tx Power Ramp Disabled - Tx power is the same at any modulation profile

• Tx Power Ramp Enabled - Maximum Tx power based on the reference modulation

The Tx Power Ramp is set depending on the modulation license of the user and depending on the LowerModulation that has been set.

7.1.7 ATPC and ACM interaction

The Automatic Transmission Power Control (ATPC) regulates the RF output power of the local transmitterdepending on the value of the RF level at the remote terminal. This value has to be preset from the localterminal as threshold high and low. The difference between the two thresholds must be equal or higherthan 3 dB.

As soon as the received level crosses the preset threshold level low due to the increase of the hop atten-uation, a microprocessor (µP), embedded in the ALFOplus, at the receiver side of the remote terminalsends back to the local terminal a control to increase the transmitted power.

MN.00273.E - 004 61

A good set of the thresholds is to put the ATPC Low Level threshold higher (or even slightly higher) thanthe threshold of the highest modulation scheme of the ACM; this way, the ATPC start to work before thanthe received signal is reduced and by consequence will force the system to downgrade the modulation. Thebehaviour of the system is to always try to increase the PTX and so the System Gain, before than beingforced to reduce capacity due to modulation downgrade.

Resuming, the correct setting of the thresholds is when the two windows, the ATPC one and the ACM one,are not overlapped, as per Fig.18.

7.2 LOOPS

To control the equipment correct operation a set of local and remote loops are made available. The com-mands are forwarded by the WEBLCT program. The available loop facilities are:

• Line Loop (Ethernet Port Loop)

• Baseband loop

• RF loop (only for GB8xxxx)

Fig.19 - Available loops

7.3 RATE LIMITING AND INGRESS FILTER POLICING

7.3.1 Rate limiting

In SIAE equipment it is possible to apply the Rate Limit, i.e. to limit the total rate passing through an in-terface. It is possible to apply the rate limiting from 64 kbit/s up to the maximum port speed (up to 1GE).

The values that can be inserted are pre-fixed from 64 kbit up to 10Mbit (64Kb, 128kb, 256kb, 512kb, 1Mb,2Mb, 3Mb, 4Mb, 5Mb, 6Mb, 7Mb, 8Mb and 9Mb), In the range from 10Mbit/s up to 1Gbit/s the limiting val-ues can be chosen by the user with a 10Mbit/s step. i.e. the minimum selectable granularity is 10Mb/s.

7.3.2 Ingress filtering policy (CIR/EIR according to MEF 10.2)

SIAE equipment allows limiting the ingress traffic rate on the basis of:

• LAN port (Bandwidth profile per UNI): a different profile is defined for each LAN port (VLAN ID andpriority are not considered in this case by the rate limiting algorithm)

• VLAN (Bandwidth profile per EVC): a different profile is defined for different VLANs (priority is notconsidered in this case by the rate limiting algorithm). Up to 64 VLAN can be managed with differentprofiles.

• VLAN + priority (Bandwidth profile per CoS): a different profile is defined for different couplesVLAN+priorities (up to 64 different cases can be managed). In this case the packet priority is alwaysconsidered by the rate limiting algorithm. More than one priority can be included in the same band-width profile.

MN.00273.E - 004 63

In general different criteria can be defined for each port/VLAN/priority. Up to 64 Ingress Filtering Policyresources can be defined and each bandwidth profile defined on the basis either of LAN port, VLAN orVLAN+priority consumes 1 of such resources.

In order to define the bandwidth profile, the following parameters must be configured:

• CIR (Committed Information rate): it is the admitted ingress rate (“green” coloured), with valuesbetween 0 kbit/s and 1 Gbit/s

• CBS (Committed Burst Rate): it is the maximum size of the token bucket of the green packets, withvalues between 0 byte and 128 kbyte.

• EIR (Excess Information Rate): it is maximum ingress rate admitted when possible (“yellow” col-oured), with values between 0kbit/s and 1Gbit/s.

• EBS (Excess Burst Rate): it is maximum size of the token bucket of the yellow packets, with valuesbetween 0 byte and 128 kbyte.

• CF (Coupling Flag): if enabled, the excess token (if any) charged into the green bucket are movedinto the yellow packet bucket.

Red packets, i.e. the ones exceeding the CIR+EIR rate, are automatically discarded. In other words, therate obtained with the sum of CIR+EIR is the maximum rate allowed to be transmitted.

The combination of CIR and EIR rates is typically referred to as PIR, or Peak Information Rate, whichrepresents the total burstable bandwidth sold to the customer.

According to MEF 10.2 (Metro Ethernet Forum) specifications, the “bandwidth profile” service attribute (In-put Filter Policing), which includes some or all of the above categories, can be defined per UNI, per EVC orper CoS identifier (CoS ID; EVC.CoS). For any given frame, however, only one such model can apply. Theservice provider meets the bandwidth guarantees by reserving appropriate network resources and employ-ing a two-rate/three-colour (trTCM) rate-limitation methodology as part of its traffic engineering policy toensure compliance by user traffic.

• Green = Trasmitted: CIR and CBS.

• Yellow = Low Priority (dropped in case of congestion): EIR and EBS.

• Red = Dropped: traffic exceeding EIR and EBS is dropped.

For any port it is possible to add a Input Filter Policy table with this selections:

• Disable

• Uni Port Based

• EVC C_Vid Based

• COS C_Vid + Priority Based

• EVC S_Vid/C_Vid Based

• COS S_Vid/C_Vid + Priority Based

According the status of 802.1q Management> 802.1q settings =

• Disable: you can select only Uni Port Based with CIR, EIR, CBS and EBS; Cf disable is ok.

• Fallback: two selections 1) EVC C_Vid Based: applied to a CVLAN C_Vid with CIR, EIR, CBS andEBS; Cf disable is ok. 2) COS C_Vid + Priority Based: applied to a CVLAN C_Vid with priority range,CIR, EIR, CBS and EBS; Cf disable is ok.

• Secure: two selections 1) EVC S_Vid/C_Vid Based: applied to a SVLAN S_Vid and a CVLAN C_Vidwith CIR, EIR, CBS and EBS; Cf disable is ok. 2) COS S_Vid/C_Vid + Priority Based: applied to aSVLAN S_Vid and CVLAN C_Vid with priority range, CIR, EIR, CBS and EBS; Cf disable is ok.

Into switch there is a total of 64 instances of Input Filter Policing for all the four ports into any radio port.

Any CVID can be used into only one port.

Into same port same CVID can be reused but with different priority.

Enhanced QoS Management

The SIAE switch scheduler provides enhanced QoS management features. Based on the ingress port (andoptionally also as a function of the VLAN-ID), there are four different modes that can be used to set thepriority of an Ethernet frame:

• Ethernet: the priority is set based on the PCP (Priority Code Point) field of the VLAN tag(IEEE802.1p) (Native 802.1p C_Vid)

• MPLS: the priority is set based on the EXP (Experimental Bit) field of the MPLS tag (Native MPLS)

• IP: the priority is set based on the DSCP field of the either IPv4 or IPv6 (Native ToS/DSCP)

• Default: the priority is set in a static mode and its value is configurable based on the Entering LANinterface. This Default configuration is a “Port Based” Priority with default priority value of 0 (lowestpriority). These priority values can be configured by the user within the range from 0 (lowest prior-ity) up to 7 (higher priority). The Default mode is also used when all the other criteria are not ap-plicable.

It is in addition possible to map the EXP quality of the MPLS label into the PCP field of the outer VLAN tag(802.1p Rewrite with MPLS). Once the priority is assigned, the packet is sent to one of the 8 output queues.The size of each one of the 8 queues is configurable with one value between the following seven options:128kbit, 256kbit, 512kbit, 1024kbit, 2048kbit, 4096kbit and 8192kbit.

On the basis of the filling status of the queue, different drop-policy can be applied. In SIAE switch thereare four available policies:

• Tail drop: if the packet is arriving into a full queue, it will be discarded

• Queue drop: if a new packet is arriving into a full queue, the whole queue is emptied (with the ex-ception of the head packet)

• RED: when a new packet is arriving into the queue it has a discarding-probability that is function ofthe filling status of the queue. the relation between the probability and the queue status is definedby means of a SW configurable curve. If the queue is full, the new packet is discarded with proba-bility 1 (like in the Tail drop case).

• WRED: it is similar to RED, with the difference that for each queue two drop’s curves are defined.the packet in ingress is coloured according to MEF 10.2, i.e.e according to the CIR and EIR ingressfiltering policy defined. As a consequence, WRED can be chosen only if CIR/EIR Ingress filtering pol-icy is enabled for the ingress port. Once coloured, “red” packets are always discarded, while “green”and “Yellow” packets are managed according to different curves.

The traffic in the queues is then emptied by means of either Strict priority or Weighted Fair Queue algo-rithm. With the Strict Priority the highest priority takes always precedence. With WFQ the available band-width is shared between the different priorities with configurable weights. It is in addition possible toconfigure at the same time some queues as Strict Priority and the remaining as WFQ.

Going into details:

• Strict Priority: first, all the packets from the highest priority queue are transmitted, then all thepackets from the second queue, and so on.

• Weighted Fair Queueing (W.F.Q.): the packets are sent on the radio following a rule based on theweight assigned to each Queue.

Each queue “i” with WFQ is given a weight (importance) Wi.WFQ guarantees a minimum service rate to queue “i”

Ri = R*Wi/(W1+W2+....+Wn) [Rate of the queue i]

Where:R = rate of the servant (capacity available on the MW link)W i= weight of the Queue taken in considerationWn = weight of the last Queue with WFQ enabled

This means that the rate of the queue is a fraction of the total bandwidth that dependson the weight assigned to the Queue.

For example if the weights are set as Fig.20.

MN.00273.E - 004 65

Fig.20 -

Means that the Serving Priority of the frames present in the queues will be:

• the packets present in the Queue 7 will be transmitted with a Race 8/35

• the packets present in the Queue 6 will be transmitted with a race 8/35

• ......

• the packets present in the Queue 0 will be transmitted with a rate 1/35.

7.4 CONGESTION AVOIDANCE

The Congestion Avoidance is a protocol that permits to discard some frames before congestion occurs.When the queue is full there is a congestion situation, this means that the resources are not enough toserve all the packets and there is not enough room in the queue for more storage. In this case some packetmust be dropped. The choice of the dropping policy has different effects on the network. In case of con-gestion, the TCP/IP protocol reduces the transmitting windows and therefore the amount of traffic trans-mitted. The TCP/IP protocol increases the transmitting window very slowly to allow the network to solvethe congestion issues.

This means that, when congestion occurs, some selective dropping has to be done.

There are different policies of dropping that can be adopted:

• Tail: in this case the last packets that come to the full queue are dropped (default configuration)

• Queue: in this case all the queue is emptied, i.e. all the packets present in the Queue are dropped

• Red: Random Early Discard: with this policy, before the Queue is full some incoming packets aredropped randomly regardless if the frames are marked yellow or green (for more details on yellowor green frames please refer to the paragraph 7.3.2 Ingress filtering policy (CIR/EIR according toMEF 10.2))

• WRed: Weighted Random early Discard: with this policy, before the Queue is full some incomingpackets are dropped randomly. First are dropped the packets coloured in yellow and then aredropped the packet coloured in green, see Fig.21.

66 MN.00273.E - 004

Fig.21 - Red curve

Once WRed is enabled the threshold of Smin Smax and Pmax for the Green and Yellow frames have to be set.

The value set the points of the curve shown in Fig.21. There are some predetermined profiles to be ena-bled:

• Profile 1:

- Smin= 30

- Smax=60

- Pmax=10

• Profile 2:

- Smin= 20

- Smax=40

- Pmax=10

These profiles can be set for the Yellow Frames (Y) and Green Frames (G) as well. These values represent:

• Smin: represents the threshold after which the switch starts dropping packets

• Sman and Pmax: are the thresholds that makes the curve of “Drop Percentage”/”Average Queue Oc-cupation” change. After this point the dropping packets increase rapidly.

• “Red Gentle”: after the point represented by Smax and Pmax: the Drop percentage can increase toa 100% (RED) or can linearly increase. the choice of how to increase, directly or linearly to a 100%is manage by disabling or enabling the RED Gentle.

• RED (Random Early Drop): no packet are dropped until Average Queue Occupation % reachesSmin(G, Green), packets are dropped randomly until a percentage of Pmax and an Occupation %of Smax(G) limits are reached, all packets are dropped over an Occupation % higher than Smax(G);

• RED Gentle (Enable): no packets are dropped until Average Queue Occupation % reaches Smin(G,Green); with Average Queue Occupation % higher than Smin(G) and lower than Smax(G), packetsare dropped randomly with a percentage defined by the straight line between Smin(G)/0 andSmax(G)/Pmax(G); with Average Queue Occupation % higher than Smax(G) the percentage of ran-domly dropped packets is defined by the straight line between Smax(G)/Pmax(G) and Sgentle(G)/100%;

• WRED Gentle (Enable): Weighted RED is a two line RED; one line for Green packets, one line forYellow packets; Green and Yellow are defined by CIR and EIR into Input Filtering Policy(Lan1,2,3,4); for Green packets no packet is dropped until Average Queue Occupation % reaches Smin(G);with Average Queue Occupation % higher than Smin(G) and lower than Smax(G) green packets aredropped randomly with a percentage defined by the straight line between Smin(G)/0 and Smax(G)/Pmax(G);with Average Queue Occupation % higher than Smax(G), the percentage of dropped green packetsis defined by the straight line between Smax(G)/Pmax(G) and Sgentle(G)/100%; for Yellow packets no packet is dropped until Average Queue Occupation % reaches Smin(Y);with Average Queue Occupation % higher than Smin(Y) and lower than Smax(Y) green packets aredropped randomly with a percentage defined by the straight line between Smin(Y)/0 and Smax(Y)/Pmax(Y);with Average Queue Occupation % higher than Smax(Y), the percentage of dropped green packetsis defined by the straight line between Smax(Y)/Pmax(Y) and Sgentle(Y)/100%;

WRED and WRED Gentle are very efficient to get the most from the radio link available traffic avoiding the“stop and go” behaviour (SAW trend) typical of congested TCP/IP traffic.

Warning: RED and WRED impact only TCP/IP traffic, not UDP traffic.

Ethernet Frame Fragmentation

QoS preserve High priority traffic, by giving it precedence during traffic congestions. However, in case ofreal time traffic also latency and jitter are important factors. Latency is strictly related to the line speedand usually can be managed by designing the network topology in a proper way (e.g. by limiting the max-imum number of hops in link chains). Jitter is instead a more sensitive parameter because it depends onthe traffic conditions.

In fact, when a High priority packet has to be sent over the radio link it is scheduled on a High Priorityqueue. However, before to be sent over the radio link it has to wait that the packet currently in transmis-sion (even a Best Effort packet) will be entirely sent. This waiting time can considerably change dependingon the best effort packet size (from 64bytes to 1518 bytes of even more in case of jumbo frames). Onetechnique used to mitigate this phenomenon is packet fragmentation, i.e. longer frames are subdivided insmaller fragments at Tx side. A label is added to the packet in order to number these subframes. At Rxside the original frame is rebuilt after all the fragments are received. In this way, the maximum waitingtime for a High Priority packet is reduced to the sub-frame size (some hundreds of bytes), providing sen-sitive benefits to the packet jitter.

The SIAE switch allows to fragment Ethernet frames with two options: 256 or 512 Bytes.

For example: in case the radio is serving a 1024Byte frame in the lowest (queue 0) and there is an incomingframe (256 bytes) in the highest priority queue (queue 7). The packet in the highest priority should beserved first, but since the servant is busy processing the packet in the lower queues, the 256Byte framehas to wait until the radio has processed the 1024 Byte frame, see Fig.22.

68 MN.00273.E - 004

Fig.22 - Ethernet frame fragmentation disabled

With the fragmentation enabled the time that the packet in higher queues have to wait is smaller. Withfragmentation enabled the radio divides the 1024 byte packet into 4 packets of 256 Bytes and the servantcan transmit the first frame of 256 Byte in the lower queue and then transmit the high priority traffic, re-ducing the jitter in the network, see Fig.23.

Fig.23 - Ethernet frame fragmentation enabled

Enhanced VLAN Management

The SIAE switch provides the following enhanced VLAN management features:

• VLAN rewriting

• Selective QinQ based on VLAN and IEEE 802.1p priority

MN.00273.E - 004 69

VLAN rewriting

VLAN rewriting is a feature available on radio side that allows to rewrite the VID of C-TAG of the packetreceived (uplink side) or sent (downlink side) by the switch.

On uplink side (packets received on LAN interface by the switch and sent to the radio) the VID can be re-written on the basis of the following criteria:

- LAN port + C-VID: new values of C-VID to be written into the packet can be configured on the basisof its original C-VID and the LAN port where it has been received.

- LAN port + C-VID + priority: new values of C-VID to be written into the packet can be configuredon the basis of its original C-VID + priority and the LAN port where it has been received.

On uplink side it is possible to configure for all the LAN ports up to 64 LAN port + C-VID or LAN port + C-VID + priority criteria.

On downlink side (packets received on radio side and sent by the switch on the LAN interface):

• the VID can be rewritten on the basis of the C-VID of the received packet. I.e., new values of C-VID to be written into the packet can be configured on the basis of its original C_VID. It is possibleto configure up to 64 C-VID criteria in downlink, independently by the uplink configuration.

• C-VID can be removed selectively. It is possible to select the C-VID, enable the option “Removed”and select the Output interface. In other words on downlink side it is possible to select the C-VIDto be remove and the correspondent Output LAN.

Selective QinQ based on VLAN and IEEE 802.1p priority

VLAN staking (also named QinQ) is a feature that allows an Ethernet frame to include more than one IEEE802.1Q TAG. The scope of VLAN staking is to differentiate the traffic at different levels when the packetsmust cross networks managed by different entities.

The SIAE switch radio supports the Vlan staking. Once a packet enters into the radio it is possible to adda new IEEE 802.1Q TAG. The VID of the new TAG can be set based on different criteria:

- Ingress port of the packet

- C-VID and priority of the packet when received on the ingress port

The new TAG is added to the packet as a S-TAG. The Ethertype field of the TAG can be set either to stand-ard values (0x88A8, 0x9100, 0x9200, 0x9300) or to any other custom values.

Packet Compression

The SIAE switch provides header packet compression. This feature allows to compress the packet headerby transmitting over the radio link proprietary labels in place of long and repetitive header field.

Multi-layer Packet Compression supports the following protocols: Ethernet, MPLS, IPv4/IPv6, UDP and RTPand LTE S1 interface tunnelling. This latter cover the case of LTE eNodeB backhauling on S1 interface,where the eUE traffic (either IPv4 or IPv6) is enveloped into a GTP-U tunnel. The Header compressed inthis case includes (IPv4+UDP+GTP-U of the S1 interface)+(IPv4/IPv6+UDP+RTP of the eUE traffic insertedinto the tunnel).

When enabled, the user can select which header have to be compressed considering the following maxi-mum limits:

• the total header field size cannot exceed 124 bytes

• the total header field size after internal coding cannot exceed 118 bytes. the internal coding is re-quired by SIAE switch in order to perform the compression task.

In Fig.24 are detailed the different header fields that can be selected with their weight in terms of headerfield size and header field size after internal coding.

LAG - Link Aggregation (IEEE 802.3ad)

Link Aggregation (LAG) is a feature available on SIAE switch that allows assigning up to 4 physical linksto one logical link (trunk) that functions as a single, higher-speed Ethernet link.

SIAE switch support IEEE802.3ad LAPC (Link Aggregation Control Protocol). LACP allows a network deviceto negotiate an automatic bundling of links by sending LACP packets to the peer (directly connected devicethat also implements LACP). In addition to the increased capacity and/or protection line of the logical linkand/or protection line, LACP provides additional advantages:

• Failover detection when a link fails, allowing for a trunk reconfiguration in order to avoid systematicpacket loss (after the reconfiguration the packets will be lost only if the throughput exceed the trunkcapacity)

• it introduces an agreement between the two LACP peers before the staring of data transmission overthe trunk. This prevent anomalous behaviour in case of cabling or configuration mistakes.

LACP works by sending frames (LACPDUs) over the links belonging to the trunk. Also the equipment de-ployed on the other end of the trunk will send LACP frames over the same links: this enables the two unitsto establish the trunk. LACP can be configured two modes: active or passive. In active mode it will alwayssend frames along the configured links. However, in passive mode it acts as “speak when spoken to” andtherefore it can be used as a way of controlling accidental loops (as long as the other device is in activemode). SIAE switch implements an “active” LACP.

A Line Trunk can aggregate up to 2 LAN interfaces with the following restrictions:

• all the LAN interfaces must be defined with the same speed (either 10, 100 or 1000 Mbit/s)

• all the LAN interfaces must be set in Full Duplex mode

When a Trunk is defined on SIAE switch, the end-to-end traffic is transmitted over all the aggregated lines.As a result, the overall capacity of the trunk can be theoretically equal to the number of aggregated linesmultiplied by the capacity of a single line. In the example of Fig.25, two full duplex - 1Gbit/s connectionare grouped into the same trunk, carrying all the capacity in transit from a radio link to another. In thisconfiguration, the line aggregation is used as line protection, although it can transport 2 Gbit/s capacity.

Fig.25 - Line trunking

To enable the Link Aggregation on both interfaces (LAN1 and LAN2), select the group “Enable - Trunk1” or“Enable - Trunk2” in Web Lct - STP/ELP trunking menu.

Line Protection through distributed ELP

ELP (Ethernet Line Protection) is a feature available on SIAE switch that allows to protect a GE interfaceagainst cable failure or accidental disconnection. With ELP it is possible to connect a switch to another net-work element by using two GE interfaces. Both interfaces are active but just one is enabled to forward andreceive traffic (forwarding state), while the other does not allow any traffic to pass (blocking state). If theforwarding interface goes down, the other one passes to the forwarding state. The maximum switchingtime is around 900msec. This feature does not imply the use of any protocol, but is simply based on thestatus of the physical interfaces. As a consequence, no particular protocol support is required on the con-nected equipment: it is simply required to enable the two GE interfaces.

It is recommended to disable any Spanning Tree protocol on the external equipment: this could cause long-er traffic recovery times.

To enable the Ethernet Line Protection on both interfaces (LAN1 and LAN2), select the group “Enable -Prot1” or “Enable - Prot2” in Web Lct - STP/ELP trunking menu.

7.5 ETHERNET OAM (OPERATION ADMINISTRATION AND MAINTE-NANCE)

This protocol can be used in any point-to-point Ethernet link. The aim of this protocol is to check and mon-itor the functionality of the service that the provider guarantees on the network.

7.5.1 Service layer OAM

The Service Layer OAM fully monitors a customer End-to-End Ethernet Service. Two main standards coverthis topic, the IEEE 802.1ag and ITU-T Y.1731.

The IEEE 802.1ag provides CFM (Connectivity Fault Management) useful for detecting, isolating and re-porting connectivity faults. The ITU-T Y.1731 Standard comprehends the CFM plus some additional fea-tures, like RDI (Remote Defect Indicator) that allows to report back to the start of the chain the Alarmmessage.

SIAE equipment support CFM according to both standards ITU-T Y.1731 and 802.1ag.

The IEEE 802.1ag and the ITU-T Y.1731 are End-to-End service, i.e. provide the tools to monitor the Ether-net Service regardless of the layers, Network Path and operators. Since the spectrum of application caninclude many applications a more hierarchical structure is needed.

The Standards define:

• Maintenance Domains (MD): these specify the Domains of operators, users and service providers.Levels from 0 to 7 are possible depending on the type of service to be monitored. Customer Domainis the higher which includes both ends of the Ethernet service (from one End user to the other Enduser), Standard Default values for Customer Domain are 7, 6 and 5. Service Provider Domainsshould have a MD lower than the Customer Domain since include the whole network except the EndUsers. Standard default values for Provider Domains are 3 and 4. Operator Domains are lower thanService Provider Domains since just a part of the network is included. Standard Default values foroperator domains are 0, 1 and 2. Here follows a picture explaining the hierarchical structure of Main-tenance Domains.

• ALFOplus: in SIAE equipment one Maintenance Domain can be specified. At each end of the Main-tenance Domain two MEPs (Maintenance End Point) will be specified. The MEPs are “markers” thatdefine the end of a domain and are in charge of originating OAM frames. In a domain also MIPs(Maintenance Intermediate Points) can be specified. The MIPs are passive check-points. The MEPsand MIPs configuration are discussed in details in the following points. The choice of the domain andthe Domain Label (name) is left to the user. Particular attenuation must be paid to use the sameMD label in each equipment where the MD is specified, i.e. different equipment with same value ofMD domain but different MD labels belongs to different Domains.

MN.00273.E - 004 73

Fig.26 - Hierarchical structure of maintenance domains

• A Maintenance Association (MA) is one association which correlates the VLAN to the MD in whichthe MEPs and MIPs have to be defined.

• ALFOplus: when a specified traffic needs to be monitored, then it is necessary to relay the VLAN toa Domain and to the corresponding MEPs or MIPs through the MA. Before creating the MaintenanceAssociation, the VLAN, either S-VLAN or C-VLAN, has to be specified in the VLAN Table. In eachSIAE equipment it is possible to set up to 32 different MA. Particular attention must be paid to usethe same MA label in each equipment where the MA is specified, i.e. different MA labels on the sameVLAN correspond to different MA associations.

• At the Edge of a MD there are MEPs (Maintenance End Points) and in the middle there could be MIPs(Maintenance Intermediate Points). MEPs are the units in charge of managing the CFM to correctlymonitor the status of the Ethernet service provided. MIPs are passive check-points that answer topollings coming from MEPs. MEPs will forward OAM messages coming from higher domains and willdiscard OAM messages generated from lower domains.

• ALFOplus: Each interface can be configured as MEP, Port A interface (radio interface) included. Oncechosen the interface, depending on the network topology, the direction of the MEP has to be spec-

ified. Two Directions are possible, MEP “ ” and MEP “ ”. With MEP “ ” configured the OAMPDUs are sent from the interface in the direction outside the equipment, i.e. the OAM PDUs are sentfrom the interface on the cable toward next equipment. With MEP “ ” configured the OAM PDUsare sent from the interface toward the inside of the equipment and will follow the VLAN table pre-viously configured. MEPs are distinguished from each other through a MEP ID, therefore MEPs be-longing to same MA must have different MEP IDs. In order to configure a MIP the MA has to behabilitated on the equipment. Up to 32 MIPs or MEPs can be configured on each equipment.

The protocols belonging to the Connectivity Fault Management implemented in SIAE equipment are listedhereafter:

• Continuity Check Protocol: this protocol enables the sending of a periodic message (like a Heartbeatmessage) which enables the other MEPs deployed in the network to distinguish the status of a vir-tual connection. this message can only be originated by a MEP.

ALFOplus: is adjustable with 1s, 10s, 1min, 10min. These messages do not trigger any automaticreply from the destination entity.

• LoopBack Protocol: it resembles an IP PING message; once this message is sent (e.g. MEP1 sendsa Loopback Message to MEP2). MEP2 replies to MEP1 confirming therefore the status of the connec-tion. This is done to check the status of the connection between the MEP originating the messageand the MEP/MIP to which the message is addressed. This message can only be originated from oneMEP and can be addressed to both MEPs or MIPs.

ALFOplus: the number of Loopback Messages in SIAE equipment is adjustable from 1 to 5 consec-utive Loopbacks. In each equipment, it is possible for each MEP to check the presence of other MEPsin the same MA. This is done through the “Remote MEP” application which allows this acknowledge-ment and distinguishes the other MEP through means of MEP IDs and MAC address.

• Link Trace Protocol: this protocol sends a message similar to the LoopBack protocol. Every equip-ment that is reached by this message will answer to the sender providing its own MAC address. Inthis way the sender is able to understand of which equipment the MA is composed. E.g. a MEP sendsthe Link Trace Message to another MEP belonging to the same Maintenance Association. the MIPsthat are deployed in the middle of the path will forward this message and answer to the initiatingMEP with their own MAC Address. By doing so the initiating MEP knows the OAM-devices deployedin the path and their order.

• Remote Defect Indicator: this feature allows a MEP, in presence of a fault or a defect, to send a RDIto inform the other MEPs, belonging to the same MA, of the presence of this Defect. The advantagesof this procedure are to avoid multiple Alarms created by the same cause and to be able to checkthe status of other Remote MEPs. This RDI information is reported in the Continuity Check Message.

ALFOplus: this feature is present in SIAE equipment and the presence of this alarm can be checkedas well in the Remote MEPs screen on the equipment.

7.6 ETHERNET PERFORMANCE MONITORING - RMON

RMON (Remote Monitoring) is a standard whose function is providing a set of services of statistics count,monitoring and alarm report with reference to the activity of a LAN network.

SIAE equipment support RMONv1, first MIB, as defined in RFC2819. This MIB contains real-time LAN sta-tistics e.g. utilization, collisions and CRC errors. These counters are managed locally into the radio equip-ment and are defined independently for each port of the device (both LAN and Radio interfaces). SIAENMS systems collect periodically this data and store it into the network database. More in details, the RMONimplementation in SIAE Network Elements is classified into two groups:

• RMON – Statistics: These are the counters data collected in real time by the Network Equipment.These data are stored in the network equipment itself and, the NMS Statistics viewer can visualizethis data with the “Refresh” button.

• RMON - History: This is managed by the NMS through the collection of the counters data from theNetwork Equipment. After a periodical polling to the Network Element, the NMS collects all the dataand these data are seen as the RMON History.

MN.00273.E - 004 75

In other words, the “RMON Statistics” are the data that are collected and stored in the Network Equipment,while the “RMON History” is an aggregation of the data collected from each network equipment and thedatabase is located in the NMS.

7.7 RMON COUNTERS

RMON statistics are composed by counters for each port of the device that are stored in the equipmentdeployed on field.

Into the equipment it can be chosen to store the values with a sampling period that can be defined betweentwo values: 1 min, 15 min, or both. For each sampling period the counters values are stored into the equip-ment. After a predefined period (polling period), all the RMON data stored by the equipment are get by theNMS. The polling period can be either less than 4 hours (if the sampling period is 1 min) or 1 day (in casethe sampling period is 15 min). The NMS aggregates the files received to create a bigger database withthe History of the Performance Monitoring samples.

Here below are described the RMON counters available for each device interface (both LAN and radioports):

• DropEvents: Total number of events (frames, or whole queue contents) in which packets weredropped by the interface due to lack of resources.

• Octets RX: Total number of octets of data (including those in bad packets) received by the interface.

• Pkts RX: Total number of packets (including bad packets, broadcast packets, and multicast packets)received.

• BroadcastPkts RX: Total number of good packets received that were directed to the broadcast ad-dress.

• Multicast Pkts RX: Total number of good packets received that were directed to a multicast address.

• CRC Align Errors: Total number of packets received that had a length between 64 and the Max Pack-et Size configured on the equipment switch (in any case not exceeding 10240 bytes) with bad FrameCheck Sequence (FCS) and an integral number of octets (FCS Error) or a bad FCS with a non-inte-gral number of octets (Alignment Error).

• Undersize Pkts: Total number of packets received that were less than 64 octets long and were oth-erwise well formed.

• Oversize Pkts: The number of packets received during this sampling interval that were longer thanmaximum allowable length (excluding framing bits but including FCS octets) but were otherwisewell formed.

• Fragments: Total number of packets received that were less than 64 octets in length and had eithera bad Frame Check Sequence (FCS) with an integral number of octets (FCS Error) or a bad FCS witha nonintegral number of octets (Alignment Error).

• Jabbers: Total number of packets received that were longer than n (parameter Max Packet Size, itcan be set to 1522, 2048 bytes or 10240 Kbytes) octets, and had either a bad Frame Check Se-quence (FCS) with an integral number of octets (FCS Error) or a bad FCS with a non-integral numberof octets (Alignment Error).

• Collisions: The best estimate of the total number of collisions on this EthLannet segment.

• Utilization Rx: The best estimate of the mean physical layer network utilization on this interface dur-ing this sampling interval, in hundredths of a percent. The percentage is always referred to a 1Gbit/s port speed. So, it represents the mean RX throughput measured on the port during the samplingperiod and it is expressed as a percentage of a port speed.

• Octets TX: Total number of octets of data (including those in bad packets) transmitted.

• Pkts TX: Total number of packets transmitted.

• BroadcastPkts TX: Total number of good packets transmitted that were directed to the broadcastaddress.

• Multicast Pkts TX: Total number of good packets transmitted that were directed to a multicast ad-dress.

76 MN.00273.E - 004

• Utilization TX: The best estimate of the mean physical layer network utilization on this interface dur-ing this sampling interval, in hundredths of a percent. The percentage is always referred to a 1Gbit/s port speed. So, it represents the mean TX throughput measured on the port during the samplingperiod and it is expressed as a percentage of a port speed.

All the counters described above are part of the RMON statistics and it is not possible to collect only a sub-set of them. It is however possible to select on which equipment interface activate the RMON statistics (forexample, they can be enabled only on the radio interface). This allows reducing the total amount of PMdata, for example avoiding data collection from unused LAN interfaces. This can be done on all PayloadInterfaces (regardless if electrical or optical), the Radio interfaces are included as well.

7.8 ADVANCED STATISTIC MONITORING FOR SERVICES AND PRI-ORITY COUNTERS

In addition to the Ethernet Counters per Port with SIAE equipment it is possible to set on the Radio interfacethe RMON counters per Service (Vlan) or Priority (Queues). Differently from the previous RMON counters,the Service and Priority counters can be activated for the following variables.

• Octets TX: Total number of octets of data (including those in bad packets) transmitted.

• Pkts TX: Total number of packets transmitted.

• Octets RX: Total number of octets of data (including those in bad packets) received by the interface.

• Pkts RX: Total number of packets (including bad packets, broadcast packets, and multicast packets)received.

• DropEvents: Total number of events (frames) in which packets were dropped by the interface dueto lack of resources.

The Service and Priority RMON can be activated and collected from NMS (Network Management System).The Service and Priority RMON are based on the Advanced Ethernet Counters present on the equipmentand configurable on site. This means that on site it is possible to activate the Advanced Ethernet Countersbut not the Service and Priority RMON.

In any case the NMS has higher priority in respect to the configuration inserted through Web LCT. Thismeans that the local operator can enable and read the active measure, but when the configuration of theseRMON is done through NMS, the local operator can only read the values of the Advanced Ethernet Counters.It is not possible to enable the RMON for Priority and, in the same equipment, the RMON per Vlan.

7.8.1 Priority RMON

The Priority RMON are based on the internal Queue of the equipment, not on the value of the Priority; thisimplies that:

• the maximum number of RMON (Priority) that can be enabled are limited to 8, i.e. the number ofthe queues available in SIAE switch.

• if traffic with different priorities are listed in the same Queue, the Priority RMON will work with oneProbe on the Queue. I.e. the traffic in the same Queue is seen as “Same Priority Traffic” and thePriority RMON counts the frames belonging to the Queue

In other words, with Priority RMON there is a probe for each queue (8 queues in SIAE switch). Each probecounts the variables listed above (Octets TX, Pkts TX, Octets RX, Pkts RX and DropEvents).

These counters will be available only with the Minimum Polling Policy of 15 min.

MN.00273.E - 004 77

7.8.2 Service RMON

The Service RMON counters allow the equipment to track the variables listed above depending on the Ser-vice (Vlan Tag). This type of RMON can be set only on the Radio interface.

Each equipment can be set to collect RMON up to 32 Services (Vlan Tag) and only on Customer Tag.

These counters will be available only with the Minimum Polling Policy of 15 min.

7.9 SYNCHRONISM

Network Synchronisation is a growing subject related to the network evolution from TDM to Ethernet pay-load.

In this chapter it will be described the different features supported by SIAE switch equipment for the syn-chronization transport. The decision of the correct source to enable and how to pass the synchronisationsignal to customer’s equipment depends on network situation which has to be evaluated case by case.

Fig.27 - Node B and BTS synch

The main concept is to transfer the synchronization signal throughout the network deployed. This impliesthat SIAE equipment will take the clock signal from the concentration points (POC) and transfer it towardsthe tail sites and distribute the synchronization signal to the external equipment such as NodeBs and BTS(see Fig.27).

Fig.28 - SETS circuit

Going into details, this means that each SIAE equipment (represented in Fig.28) will have, at least, one“Input” and one “Output” CK.

Input (CK IN) is/are the interface/s where the SIAE equipment get the Clock signal from, these could beanother SIAE IDU or external equipment.

Output (CK OUT) is/are the interface/s where the SIAE equipment provides the Clock Signal to, these couldbe another SIAE IDU or external equipment.

Internally to each SIAE equipment the SETS identify the input and output types of interfaces by the fol-lowing codes:

• TE: This code represents an Ethernet interface (LAN) used as input CK

• T0: Output interface. This code represents the Internal Clock

The purpose of the above list is to list the different acronyms used by the SETS that may be present in theconfiguration screens.

When the Synchronization is enabled in SIAE MW equipment, in the configuration screen, there are somefeatures to be used for maintenance or refined tuning of the clock propagation.

Fig.29 - Synchronisation menu

Here below are listed the different configurations to be made:

• Status Control: this is a forced status for maintenance purposes of the SETS. It can be forced in:

- “Free Running”: Independently from the synchronization signal received, the clock is locked ontothe internal clock.

- “Hold Over”: The SETS is locked into the internal clock which tries to preserve the frequencyreceived when the SETS was locked.

- “Locked”: in this case the SETS is locked to a source of synchronization.

- “Hold Off Time”: Time (expressed in ms) during which the system keeps the evaluated frequen-cy of a synchronism source become invalid (not present or degraded). At the end of the HoldOff time, the invalid source will be rejected and the first input source having a valid signal willbe used.

7.10 SOURCES OF SYNCHRONISM

SIAE equipment is able to select among different sources of synchronization. A priority has to be assignedto enable each source, with a value ranging from 1 to 9 included. The priority 1 corresponds to the maxi-mum value, while the priority 9 corresponds to the minimum value. The priority shall be used to select inwhich order the different synch sources must be used. In case the Priority is set as “Disabled” the corre-spondent interface is not used as a synchronization source.

Fig.30 - Sources of synchronisation

The selectable sources of synchronisation are listed below. For each source it is also listed in square brack-ets the correspondent acronym used by the SETS:

• Radio Interface: it is possible to have 1 radio interfaces (1+0).

• GE Interface [TE]: to identify which LANs are the sources of synchronization they have to be chosenunder “TE LAN A” and “TE LAN B”. This implies that a maximum of 2 LAN interfaces can be set assource of synchronization. The AGS-H reference clock can be received on any one the 4 LAN inter-faces, independently from the fact they are electrical or optical. In order to receive the synchroni-zation signal (and regardless of the SSM status) the GE interface has to be set as “Slave”. Theconfiguration choices and other details are explained in “SSM on Ethernet Interfaces”.

• Internal Clock [T0]: with the Synchronization not enabled the IDU is locked into its internal clock

In case SSM is not enabled, the equipment switches from one source of synchronization to another follow-ing the priority scale, starting from the source set to priority 1 and scaling to the sources with higher valuesof priority (i.e. lower priority level). The synch source switch occurs when the present source suffers oneof the following events:

• The source of synchronization is not physically available

• The clock deviation is bigger than 4.6 ppm (maximum deviation that the internal clock can follow).

In other words, if the LAN1 is selected as first source (priority 1) of synchronization, and the LAN2 is se-lected as the second source (priority 2) of synchronization, the SIAE equipment will be synchronized onthe LAN1 until the cable will be physically unplugged or the LAN1 frequency and phase will be out of theirspecified ranges. Once one of these events occurs, the SIAE equipment will switch the source of synchro-nization to the second source listed. If the second source listed is unplugged or out of maximum range thenthe SIAE equipment will switch to the third source and so on. In case no other synch sources are available the SIAE equipment will go on “Internal Source”, i.e. the in-ternal clock present in SIAE equipment. In this condition the internal clock will be kept in hold status, tryingto keep the last synchronization reference received. In these conditions, the internal clock of SIAE equip-

80 MN.00273.E - 004

ment has a reliability of 0.3 ppm over 24 h. When the SIAE equipment switches to internal clock, it prop-agates a quality of SEC – SDH Equipment Clock.

7.11 PROVIDE SYNCHRONISM TO EXTERNAL EQUIPMENT

Once the SIAE equipment is synchronized, the clock signal has to be passed toward external equipment orother SIAE equipment. SIAE equipment can give the synchronization signal through different interfaces.

Fig.31 - Provide synchronism

The interfaces that are available to provide synchronization to other SIAE or external equipment are:

• Radio: this interface is passing the synchronism automatically to the remote equipment. No config-uration is needed.

• GE Interfaces: the TX CK of the all GE lines (i.e. LAN 1 and 2) is locked to the SETS. In this way,the CK can be passed through these connections to other equipment provided that they supportSynchronous Ethernet. The GE Interfaces when used in Electrical can provide the CK signal to otherequipment: in this case the equipment port role must be “Master”. Once the synchronization is en-abled in the SIAE equipment, automatically all the LAN interfaces are locked onto the SETS. Thisimplies that the synchronization signal is automatically provided onto all the LAN interfaces.

The choices of the interface to pass the clock signal depend strictly on the external equipment. This meansthat in first place it is necessary to establish the possible sources of synchronization available on the ex-ternal equipment. Depending on the availability of these sources, SIAE equipment will be configured withthe correspondent interface to pass the clock signal.

MN.00273.E - 004 81

7.12 G.8264 SSM – SYNCHRONISATION STATUS MESSAGE

The SSM is a protocol that transmits the quality of the synchronization message throughout the network(G.781).

In the synchronization network the transmission of the quality of the clock allows the network to be scal-able and to provide redundancy. In case of failure of SIAE equipment or cable, it is helpful to provide re-dundancy for clock propagation in order to avoid synchronization loops.

Synchronisation loops could happen after a failure when two equipment are synchronising each other onthe same physical connection. If this happens the equipment will not present any alarm on the synchroni-zation but will generate and propagate a not reliable clock. The quality of the clocks that are propagatedare:

• PRC: Primary reference Clock – Best quality clock reachable (Cesium Clock)

• SSUT: Synchronization Supply Unit Transit (Rubidium Clock)

• SSUL: Synchronization Supply Unit Local

• SEC: SDH Equipment Clock (Crystal Clock)

• DNU: Do not Use – This signal informs the receiver to do not use this clock

Here above are listed in order from the better quality clock (PRC – Primary Reference Clock) to the worsequality clock (DNU – Do Not Use). The better the quality is the more time can the SIAE equipment stay inholdover (Internal Clock) without a degradation of the payload. In other words, better is the quality, longercan remain reliable the clock in holdover cases.

The DNU quality is always propagated on the source on which the equipment is locked for synchronization.In this way the Loops of synchronization are easily avoided.

Unless the user forces the CK quality input/output, SIAE equipment reads the quality present in the inputinterfaces. This means that, unless there is some user’s modifications, SIAE equipment propagates thequality of the clock as it is. I.e. the output quality is the same as the input quality.

E.g.: If in the input interface (POC Site) there is a quality of SSUT of the CK signal, SIAE equipment willpass throughout the network this synchronization signal with a quality message of SSUT.

In case the SIAE equipment is in Holdover (internal clock) it changes the quality of the synchronization to“SEC” quality. With SSM enabled, SIAE equipment will choose the sources of the synchronization based onthe better quality received.

In general, the equipment selects the synch source with the following criteria:

• it chooses the sources with the highest quality

• if more than one source have the same quality, the one with the highest priority is selected (i.e. theones that have the smaller priority value, from 1 up to 9)

• in any case, if a DNU quality is received on the highest priority source, this latter is discarded andthe equipment selects an alternative source.

Example 1: if one SIAE equipment has the two following sources of synchronization, with the same priority:

a. LAN1 with quality SEC (Priority 1)

b. Radio with quality SSUT (Priority 1)In case the sources have the same priority, the SIAE equipment will switch the source of synchroniza-tion to the best quality, in this case (b) the Radio with SSUT quality.

Example 2: if one SIAE equipment has the two following sources of synchronization, with the different qual-ity and different priority:

a. LAN1 with quality SEC (Priority 1)

b. Radio with quality SSUT (Priority 2)In case the sources have different priority and quality, the SIAE equipment will switch the source ofsynchronization with higher quality, in this case (b) the Radio with Priority 2 and quality SSUT. Howev-er, if a DNU quality would be received on Radio, the IDU will switch the synch source to LAN1 interface.

Example 3: if one IDU has the two following sources of synchronization, with the same quality:

a. LAN1 with quality SSUT (Priority 1)

82 MN.00273.E - 004

b. Radio with quality SSUT (Priority 2)In case the sources have equal quality, the SIAE equipment will switch the source of synchronizationwith higher priority, in this case (a) the LAN1 with Priority 1 and quality SSUT. However, if a DNU qualitywould be received on LAN1, the SIAE equipment will switch the synch source to Radio port.

The quality of the synchronism has to be enabled for each SIAE equipment and can be transported on thefollowing interfaces:

• On the Ethernet Interfaces through a standard protocol (according to ITU-T G.8264)

• Radio interface with Local/Remote Telemetry: Depending on the MW link configuration (1+0) theSSM messages are passed to the remote SIAE equipment in different ways.

- 1+0 Configuration: In this case there is one Local/Remote Telemetry passing the SSM messages

Within this configuration table there are also some maintenance configurations such as:

• Forced Switch: this command allows the operator to force the SETS to lock to a predeterminedsource. This command is above all other configurations. This means that the SETS will be lockedonto this source even if the cable is unplugged

• Preferential switch: In case two sources have equal priority it is possible to set a Preferential Source.In any case the quality is the main parameter of choice, then when two sources have the same pri-ority, the preferential source is chosen.

In relation to the SSM, it is possible to:

• Visualize the quality of the clock signal received and transmitted (Rx Quality and Tx Quality)

• Overwrite the Quality received or transmitted (Ovw Rx Qlty and Ovw Tx Quality) and the choicesare:

- PRC: Primary reference Clock – Best quality clock reachable (Cesium Clock)

- SSUT: Synchronization Supply Unit Transit (Rubidium Clock)

- SSUL: Synchronization Supply Unit Local

- SEC: SDH Equipment Clock (Crystal Clock)

- DNU: Do not Use – This signal informs the receiver to do not use this clock

The Overwrite of the Quality of the Clock is configurable by the user and simply forces in input or outputthe quality.

7.12.1 SSM on Ethernet Interfaces

In order to propagate the clock signal through the Ethernet 1GE Electrical interface it is necessary to setcorrectly the master and slave option for each interface. It is possible to assign the roles (Master or Slave)statically (as set up for source LAN) or dynamically (according to Synch direction).

This because the Master interface transmits the clock to the Slave interface and in case the direction ofpropagation of the clock has to be changed (line failure, insufficient quality, etc..), the master and slaveassignment has to be re-negotiated with a consequent loss of traffic. This re-negotiation implies an inter-ruption of the traffic from 2.4 to 2.6 seconds.

SIAE equipment allows to set the role of the interfaces to “According to synch direction” (dynamic), theflow of the propagation of the clock signal is automatically changed depending on the transferring directionof the CK.

If the role of the interfaces is set to “As set up for source LAN” (Static), the flow of the propagation of theclock signal is fixed (see Fig.32).

Fig.32 - LAN synchronisation method

MN.00273.E - 004 83

The other configuration present in SIAE equipment that manage the role of the LAN interfaces (Master/Slave) is present in the main configuration of each LAN interface. Regardless if each LAN interface is setmanually as Master/Slave or with autonegotiation, the setting of dynamic or static in the SSM configurationis privileged. In other words if the Master/Slave are set manually in the interface configuration and in theSSM is set “According to synch direction”, if needed, the role of the LAN changes according to synch direc-tions.

When an electrical GE interface is in Master State (despite from the fact that it comes from a “static” or“dynamic” setting) every synchronization signal that is coming from this interface has automatically thequality of DNU. This does not occur for optical GE or FE interfaces (Electrical and Optical), where the “Mas-ter” and “Slave” roles are not foreseen and so the transmitting direction for the clock can be exchangedwithout any port role re-negotiation.

All the Ethernet interfaces are locked on the SETS, regardless which LAN interfaces are set as sources ofsynchronization. Nevertheless the “Overwrite RX Quality” and “Overwrite TX Quality” can be applied onlyon the LAN interfaces used as sources of synchronization.

8.2 GENERAL

The ALFOplus radio system is made up of an outdoor unit, protected by a metallic shield.

Compliance to electromagnetic compatibility is guaranteed through the following precautionary measures:

• during the design phase

- use of protection circuits against electrical dischargers

- use of filters on the power supply input circuits against noise propagating on the power supplywires

• during the installation phase

- use of shielded cables

- use of ground connections.

The installation phases of the whole system are described in the following paraghaphs and it must be doneonly by service person suitably trained.

Attention: Remember that the whole radio link can work only if ODUs, chosen for local and remote side,have equal subband and different Tx module (H and L).

8.3 ELECTRICAL WIRING

The electrical wiring must be done using appropriate cables thus assuring the equipment responds to theelectromagnetic compatibility standards.

The cable terminates to flying connectors which have to be connected to the corresponding connectors onthe equipment front.

Position and pin-out of the equipment connectors are available in this section.

8.4 CONNECTIONS TO THE SUPPLY MAINS

During the final installation, protect the ODU by a magneto-thermal switch (not supplied with the equip-ment), whose characteristics must comply with the laws in force in one’s country.

The disconnection from the supply mains is made disconnecting the auxiliary connector M12P5 from theODU or disconnecting the LAN PoE cable.

The typical magneto thermal switch has characteristics at least 48Vdc @1.5A with overcurrent relay class“C” or “K” tripping curve.

Seal the auxiliary power connector when the radio is powered via PoE, in order to avoid the removal of thecover without tools.

8.11 USER CONNECTORS

ALFOplus provides an auxiliary connector and 2 types of Amphenol connector, which guarantee Ethernetport compatibility for both version: Gigabit electrical and optical.

8.11.1 Auxiliary connector

The auxiliary 5 pin circulator connector has various functions and it is used when:

• the Power over Ethernet injector through the data Lan cable is not available or as additional powersupply source (48Vdc in 1+1 configuration)

• during the alignment of antenna (remember to enable received signal strength indicator inEquipment menu - General preset RSSI.It is recommended after the alignment to set RSSI as Disable not to overload CPU.

• In case of emergency, if ALFOplus IP address is unknown, connect it with serial console (F03594),as shown in Fig.56 using hyperterminal 115200 8, N, 1 and press any button o access in the login

The available auxiliary cables already assembled:

• F03594 cable for laboratory use only (see Fig.56)

• F03608 2xM12 5P pointing cable (remove it after commissioning pointing) (see Fig.57)

9.6 OPTIMIZING ANTENNA ALIGNMENT WITH RX MEASUREMENT

When the whole radio link is on, antenna alignment can be optimised. Antenna alignment optimization isperformed depending on the Rx signal power at local and remote equipment and evaluating both local andremote S/N value maximizing them.

There are two possibilities to see the Rx signal power level:

• through WebLCT interface

• through a voltmeter connected to Auxiliary connector on the ODU (F03608 cable - see Fig.57).

In order to get the Rx signal power level by means of software, connect the PC to serial input of ALFOplus(LAN2) and start the communication towards the ODU microcontroller with SCT/WebLCT supervisory pro-gram.

Into WebLCT is shown in the top status bar (Rx1A=-value dBm) see Fig.73.

If you’re using a voltmeter the Rx signal power level is available on the auxiliary connector of ODU, themeasurement can be performed with a proper cable (see Fig.57).

Following this last procedure, the voltage you’re reading with the voltmeter is proportional to Rx powerlevel, refer to Tab.27.

Tab.27 - Voltage measured in auxiliary port

Typical Rx signal power level: -40dBm. It is the most important item to optimise the antenna alignment,but in a situation of interference Rx level can be good, BER acceptable but BER margin low. This meansthat when Rx fields will decrease then BER will increase fast. The situation can be easily shown with SCT/WebLCT software looking at Signal Quality level.

Into WebLCT Software select:

• Equipment menu

• Maintenance

• S/N Meas. card (see Fig.75)

Refer to the “ALFOplus operator” manual for parameter evaluation.

- horizontal ± 15° operating on the nut (3) shown in Fig.76, only after having loosenthe nuts (7), (8), (9), (10) of Fig.77.

- vertical ± 15° operating on vertical adjustment worm screw (2) shown in Fig.76only after having loosen nuts (1), (2), (11) of Fig.77 and (4) of Fig.76For adjustment from 0° to +30° extract nut (1) Fig.77 and position it inhole (4), extract nut (2) Fig.77 and position it in hole (6). Operate on vertical adjustment worm screw (2) after having loosen nuts (1), (2), (11) ofFig.77 and (4) of Fig.76.For adjustment from 0° to –30° extract nut (1) of Fig.77 and position it in hole(3), extract nut (2) of Fig.77 and position it in hole (5). Operate on verticaladjustment worm screw (2) after having loosen nuts (1), (2), (11) of Fig.77and (4) of Fig.76.

For vertical adjustment some markers, every 10°, are available on support. The bigger marker gives 0°starting aiming position. Once the optimum aiming position is obtained, tighten firmly the four nuts (1),(2), (11) of Fig.77 and (4) of Fig.76 for vertical adjustment and the four nuts (7), (8), (9), (10) of Fig.77for horizontal adjustment. Tighten with 15 mm wrench and 32 Nm torque.

9.7 ODU ACCESSING AND REMOTE MANAGEMENT

Local ALFOplus ODU and its remote ODU can be accessed at LAN2 or LAN1 ports (depending on supervi-sioning parameters). Once the radio link has been configured, connect to the local ODU and specify thenetwork password too. SCT/WebLCT window shows also a field referred to the remote ODU:

• double click on this field -> remote ODU is opened in monitor mode

• if it’s necessary to act on remote ODU you have to login on remote ODU (IP address is known be-cause you can read it from monitor windows).

If the remote element list has been done correctly, into WebLCT software press button Open Far End toopen and manage the Remote Radio window.

11 ALFOPLUS MAINTENANCE AND TROUBLESHOOT-ING

11.1 GENERAL

In the following pages are listed all the procedures to follow for ALFOplus maintenance.

When corrective maintenance is necessary, a troubleshooting procedure helps the operator to identify thefailure unit to replace it with a spare one.

11.2 MAINTENANCE

Maintenance consists of two stages:

1. periodical checks to be carried out using SCT/WebLCT

2. corrective maintenance.

Periodical checks serve to detect correct radio performance without the presence of any alarm condition.

Corrective maintenance takes place as soon as one or more alarm conditions are in existence. Operationsequence to be carried out is shown in “Troubleshooting” paragraph.

11.2.1 Periodical checks

System routine maintenance consists in a series of routine checks aiming to verify correct operating modeof an alarm–free system.

These checks are made through SCT/WebLCT program, installed on a PC.

The items to be checked are:

• Tx power (i.e., attenuation value in dB vs. nominal value)

• Rx field (value measured must comply with that resulting from hop calculation)

• S/N (presence of possible interference)

• BER (values measured must comply with hop calculations)

How these operations are carried out is specified in “Line–up” section or, more widely, in ALFOplus softwaremanual.

140 MN.00273.E - 004

11.2.2 Corrective maintenance (troubleshooting)

Corrective maintenance starts as soon as one or more alarm indication become active.

Corrective maintenance purpose is to locate the faulty unit and replace it with spare after having verifiedthat the cause of faulty is not external to the equipment.

Corrective maintenance does not include malfunction due to a wrong or incomplete configuration of thesystem or to failure due to alarm indication system itself or any other cause external to the system, i.e.:cabling damage, main voltage loss, antenna misalignment and propagation problems.

See paragraph 11.3 TROUBLESHOOTING for details.

11.3 TROUBLESHOOTING

Main purpose of troubleshooting is to declare an unit faulty or not.

After this step alarms are caused by bad configuration and/or external causes.

11.3.1 Faulty condition detection

Alarms can be pointed out through unit LEDs and/or through SCT/WebLCT software:

Unit LEDs

Near the circular connector of the ODU it’s shown the status of a LED, which can be green or red. The in-formation provided are:

• Red light

- ON – An internal alarm is active. Connect SCT/WebLCT for troubleshooting.


• Green light

- Flashing – No radio connection with remote ODU. In this case, if remote equipment is on andproperly oriented, it is necessary to evaluate the alarm list with SCT/WebLCT software.

- ON – Radio connection with remote ODU is active.

SCT/WebLCT

Alarms are divided in classes to refer to a particular hardware or software functionality and are character-ized by their programmable gravity.

A window with alarm classes list is available for local ODU (the unit PC is physically connected to) and forremote ODU.

The presence of a current alarm is pointed out by SCT/WebLCT program, see software manual.

The presence of an historical alarm is pointed out in the event log window of SCT/WebLCT program (seeFig.81 and Fig.82).

MN.00273.E - 004 141

11.3.2 Troubleshooting of a faulty unit

Into SCT/WebLCT software, in Equipment menu select View Current Alarm menu.

In this window they are displayed the current alarm and their severity. Depending on which alarm classesare active, following situation can arise.

ODU alarm classes active

ALFOplus is made up by a single unit, the ODU. This is the minimum spare part.

If one or more of the following conditions occur, the ODU is faulty:

• One or more alarms inside the ODU hardware class are active

• One or more alarms inside ODU link class are active

If the following condition occurs a further investigation is necessary:

• Sw config alarm in ODU software class is activeEvery log window has to be inspected. In the window are present additional information about Swconfig alarm; if it is impossible to clear through restart, the unit is not able to work properly andneeds to be tested again in SIAE final test department.

Troubleshooting on remote ODU

With SCT/WebLCT program the alarm on the Remote ODU are displayed the same way as for the local one.The above described troubleshooting can be carried out for the remote ODU too.

Section 6.PROGRAMMING AND SUPERVISION

12 PROGRAMMING AND SUPERVISION

12.1 GENERAL

ALFOplus is programmed and supervised using a software tool: SCT/WebLCT. This subject is fully describedin the separated software manual (WebLCT ALFOplus - Software application for the management of ALFO-plus equipment).

12.2 SUPERVISION THROUGH ETHERNET

The provided structure for Ethernet traffic defines the management facilities of "ALFOplus" unit.

144 MN.00273.E - 004

Fig.83 - Traffic management of "ALFOplus" unit

12.2.1 General

In general you suppose that the equipment performs the "host" functionality in an Ethernet network andthat supervisory network follows the traffic routing, eventually separated by "VLAN tag". The managementcan be:

• Disable the Management by “Ge LAN1” can’t get access to the controller

• Local Access Only “Ge LAN2” may access only to the access only to the local controller. Supervisory network is not connected to radio side

• In-Band The management can access to the controller if it’s configured with “VLAN tag”

• Out-of-Band “Ge LAN2” can access to local controller and supervisory network is connected to radio side using “VLAN stacking” function to separate the traffic

• In-band-drop-node “Ge LAN2” can access to local controller and the port is considered as anode into the supervisory network “in-band” (with VLAN tag)

The modalities can be enabled/disabled by software to the LAN1 and LAN2 interface.

Supervisory network can be disable selectively line side and radio site.

Local access to the unit must be always guaranteed by "Ge LAN2".

12.2.2 Configurations

Possible configurations of supervisioning traffic are shown in Tab.30.

Tab.30 - Configurations

12.2.3 "Local Access only" management

This modality allows the access to "ALFOplus" unit only with the local "Ge LAN2" in the easiest possibleway, with frames without " VLAN tag" and therefore with IP domain shared. This modality can be used ifthe user is IP addresses owner and so the equipment is inserted into a traffic network level 3 (IP routing).For this reason, the Security management is defined by the operator using the function (Access ControlList).

12.2.4 "VLAN based in-band" management

This procedure allow the access of "ALFOplus" unit by "Ge LAN1" more safely, because the IP domain isindependent of payload traffic through dedicated "VLAN tag" (configurable). This mode can be used whenthe user is owner of "VLAN tag" and the equipment is interposed in a level 2 network traffic (switching).In that case the management routing is obtain to filtering of "VLAN tag".

Fig.85 - VLAN based in-band management

To reduce the visibility of the controller to line side (), radio side () and extent supervision network ()you can enable or disable the paths indicated in filtering "VLAN tag". The path () can be enabled only ifboth line ports, are enabled to "In-band" management.

In case of protection configuration through LAG or ELP, the path () cannot be enabled.

12.2.5 "VLAN based In-band" drop node

This particular way allows to introduce the supervision traffic "VLAN based In-band" (mandatory with"VLAN tag") using "Ge LAN2" obligatorily without "VLAN tag". The line ports are linked together using thefiltering "VLAN tag" (set as tagged the default port "Ge LAN2").

Fig.86 - VLAN based In-band drop node

This mode allows the supervision of outdoor units placed in the same site, but excludes the possibility ofsimultaneous monitoring "Out-of-band" in the network.

The insertion direction (on the line and radio side) can be selectively enabling or disabling the paths cor-responding ( and ). This mode is not available in the case of interfaces in a secure configuration.

12.2.6 "Out-of-band" management

This mode allows the access to the local "ALFOplus" unit of frame without "VLAN tag" and the extension ofthe supervision network to the remote terminal. The priority of management traffic is obtained with "VLANtag".

In remote terminal the payload and management traffic are again divided. This involves increasing thelength of traffic frame of four bytes.

Fig.87 - Out-of-band management

12.2.7 Configurability

The management mode of equipment affects the Ethernet Channel and on the Switch configuration (RSTP,OAM, …). Therefore it is important to decide the optimal configuration of traffic Ethernet and management,to avoid blocking traffic conditions.

12.2.8 Address

The unit uses a single IP address associated at the management port of controller and a single "defaultgateway". Depending on the configuration of these addresses are visible from supervision "in-band" and"Out-of-band".

12.2.9 Restore supervisioning access mode

The “RESTORE OF CPU ACCESS” command is available through Serial port (F03594 cable) via Hypertermi-nal (115200bps,n,8,1):

• Login SYSTEM

• Password SIAEMICR

• Type string: lao

This string restores the factory default of port configuration:

• LAN1 disable

• LAN2 local access only
