3.7. ETHERNET OVER SDH (EOS)
3.7.1. NEXT GENERATION SDH
The goal of Next Generation SDH is to transportdifferent type of services, both circuit mode andpacket mode at the same time. By incorporatingdifferent technologies the aim is to keep thestrong points and eliminate the weakness.The main points are:
- Multiservice transport based on SDH.SDH has efficient protection services as wellas mature technology.
- The flexibility of the “trail” creation is
carried by virtual concatenation andLCAS protocol. The virtual concatenationallows stacking of bandwidth of differentVC12,VC3 or VC4 containers, in order toget the virtual container to an adjustablebandwidth according to the needs. Thegranularity respects 2 Mb/s, 50 Mb/s or150 Mb/s. LCAS protocol insures theextremity synchronisation when there isan adjustable bandwidth, avoids themomentary interruption services.
- Choosing the best encapsulation modefor each services :
- The in circuit flow mode, as a flow of E1
PDH end E3/DS3 that are encapsulated in avirtual container (VC12/VC3) in following themultiplexing scheme proving SDH efficientquality.
- In flow packet mode using the new GFP-Fencapsulation mode which combine very lightoverhead, with the maintenance of the octetalignment and the packet size.
- The important innovation of thetranslater for “Ethernet in the firstmile” for transporting the flow ofEthernet packets: policing, shaping,double tagging, Ethernet Privat Line,Ethernet Virtual Private Lan.

FUNCTIONAL DESCRIPTION
DTC SAGEM– ADR622 – AET/SYS/2009-D0351 – 01/09 12 /23
4.5. PROTECTION
All the main protection modes are possible withthe SAGEM – ADR622:
• STM-n MSP 1+1 (for STM-1 and STM-4 incase of point to point)
• VC12, VC3 or VC-4 path protection (SNC-P)
4.5.1. MSP PROTECTION 1+1
STM-n line protection is obtained by doublingthe fibber optic cable and the STM-n interfacemodule (1+1):
transmission over two channels, main andbackup
Receiving-end selection from either channel.There is automatic switchover to the protectionlink in accordance with the criteria described inITU-T recommendation G.823. There is nointerruption to the orderwire and data flows withMSP 1+1 protection.
Protection switching is initiated upon:
• a line fault,
• STM-n interface module fault,
• an operator command.
When detected on the main channel, thefollowing fault conditions initiate MSP protection:
SF (Signal Fail): logic ORing of:
− STM-n incoming signal loss (LOS STM-n)
− STM-n loss of frame alignment (LOFSTM-n)
− STM-n multiplex section AIS detection(MS-AIS)
− Byte B2 excessive bit error rate (EBER-B2)
− STM-n interface module absence.
SD (Signal Degrade): B2 bit error rate greaterthan configurable threshold.
The SF and SD indications are processed andfiltered (fault persistency filter with configurabletime persistency). This activates the K1/K2protocol described in ITU-T recommendationG.783 to initiate the protection mechanism.
4.5.2. (SNC-P) 1+1 PATH PROTECTION
SNC-P path protection is used in ring topologies
and consists in using the two sides of the ring:one for the normal path, the other for the backuppath.
When detected on the main channel, thefollowing fault conditions initiate a switch:
SF (Signal Fail): logic « OR » of:
− AIS detection at path termination (LP- AIS)
− Byte B3 excessive bit error rate (EBER-B3)
SD (Signal Degrade):
B3 bit error rate greater thanconfigurable threshold.
The SF and SD indications are processed andfiltered (fault persistency filter with configurabletime persistency).
The switching process lasts approximately 50ms after confirmation of the originating fault, andthe switch status is maintained until tributarysignal restoration.

FUNCTIONAL DESCRIPTION
DTC SAGEM– ADR622 – AET/SYS/2009-D0351 – 01/09 13 /23
4.6. SYNCHRONISATION
The SAGEM – ADR622:
uses its own timing source to synchronisetransmission via the STM-n interfaces,
can provide the synchronisation for otherequipment,
can be synchronised to an internal or anexternal source.
Synchronisation is performed by the Switchcard and therefore can be protected in 1+1.
4.6.1. SYNCHRONIZATION SOURCES
The SAGEM – ADR622 may be synchronised tothe following alternative timing sources:
• Tributary or aggregate STM-n signals,
• Tributary 2Mbit/s
• ITU-T G.703-compliant 2048 kHz externalclock signal,
• the internal local oscillator (+/- 4.6 ppm).
• Enabling the operator to plan thesynchronisation through all aggregates, alltributaries and external synchronisation of itsnetwork.
4.6.2. AUTOMATIC MODE
In the event of a failure of the active syncsource, synchronisation switches automaticallyto one of various prioritised standby syncsources. This switching mechanism can bereversible. Synchronisation information is carriedand processed by S1 byte.
4.6.3. MANUAL MODE
It is possible to force-manually to one of theavailable sources.
4.7. OVERHEAD
4.7.1. OVERHEAD BYTE PROCESSOR
Path overhead (POH) and section overhead(SOH) bytes, which are added to and droppedfrom the STM-1 frame, carry various items ofsupervisory information relative to the STM-1links:
• frame alignment bytes,
• parity check data,
• engineering orderwires and digital servicechannels interchanged by both ends of anetwork.
4.7.2. ENGINEERING ORDERWIRES ANDDIGITAL SERVICE CHANNELS
A digital channel (E1 or F1 overhead byte) in theSTM-n frame is reserved for transport of a digitalengineering orderwire (EOW). Digital servicechannel protection is as with 1+1 line protection.The E1 and F1 bytes are available over aSubD/HE5 connector on the AUX module frontpanel. One AUX module is needed per direction.To have a voice signal EOW, it is necessary tohave an external mechanism (SAGEM-
EOW300) which adapts the 64 kbit/s digitalsignal of the E1 and F1 interfaces.

In SDH networks, the system penalty does notaffect optical output power parameters becausethe latter include temperature variations(5°C/45°C) and above all ageing.

7.1. SUPERVISION
7.1.1. LOCAL SUPERVISION
The SAGEM ADR622 includes an HTTP serverenabling any PC with an Internet browser to beused as a Local Craft Terminal.
Local Management is performed with traditionalalarms, performances, configuration and Faultfeatures.
A VT100 console is connected to the RS232 (F)
interface which enters the IP address.The interface is serial asynchronous type - 8 bitswithout parity - supporting 19200-baud datainterchanges.
INFORMATION CONTENT
The screens are in English. The user hasaccess via a screen menu to sections relating to:
• hardware and software inventory,
• configuration of basic functions,
• basic functions alarms report,
• Performance monitoring.
Downloading
The SAGEM – ADR622 can be downloaded
locally and from the centralised managementsystem. This function is particularly useful whensoftware modifications are required, e.g., theaddition of new functions.

7.1.2. CENTRALIZED MANAGEMENTIONOS-NMS
SAGEM NETWORK MANAGEMENT SYSTEMIONOS NMS manages networks with SAGEM ADR155c, SAGEM ADR622, SAGEM ADR2500eXtra and SAGEM ADR10000.
The management network is composed of anEthernet LAN which includes a workstationsupporting IONOS-NMS (PC or SUN Server). Atleast one of the SAGEM - ADR155c or ADR622or SAGEM ADR2500 in the network (thegateway equipment) is linked to the manager.The ECC channel relays supervision information
to the SNMP manager.
ECC channel communications are protected inthe same way as the SDH line.
There are two possible centralised managementlevels:
network view:showing all network links,
Equipment view:showing modules in a particular equipment unit.
The functions available are identical to those
offered at local operating level.

7.2. MAINTENANCE
7.2.1. ALARMS
The SAGEM – ADR622 System providesoperators with various fault detection and faultycard isolation facilities for maintenancepurposes.
On the SAGEM – ADR622 equipment:
• Color-coded LEDs on each card,
• Two network management relay contactalarms.
• Via the NMS:
•
current alarms status,• alarm and performance event logs,
• network, link or equipment level view.
The SAGEM – ADR622 has four remotesignalling inputs ("TSIG") for external equipmentalarm notification.
7.2.2. SELF-TESTS
The SAGEM – ADR622 software carries out
software self-tests:
at start-up,
periodically,
upon insertion of a new module.
These routines are transparent to operationsand do not affect service.
7.2.3. LOOPBACKS
The SAGEM – ADR622 has integrated loopbackfunctions to aid the operator in diagnosing local
multiplexer or network faults.
STM-n Line Loopback
Equipment loopback applied to the main orstandby STM-n line is used for testing theequipment. Line loopback applied to far-endequipment via the main or standby STM-n line isused for testing the transmission path.
