Tx Mod Inverted Spectrum (only if BB-Modem is connected to ODU Narrowband)

This parameter inverts the transmission spectrum of the modem and it must be properly set for the Narrowband

ODUs, in accordance to what reported in the hardware manual. In case of wrong configuration of the parameter,the traffic is interrupted.The operator can choose one of the two values: Inverted and Not Inverted. (Normally is the Not Invertedselection).

XPIC Status

It indicates the status of XPIC canceller: ON or OFF (on in case of Co-channel system)

XPIC

This parameter is meaningful only for co-channel systems. It allows cancelling the residual of the orthogonal. Theoperator can choose between one of the two values: ON (canceller running, manual operation) and Forced OFF(canceller disabled).

Note that the allowing of field for IF power and Tx Spectrum Inversion depend to the system SVR andsystem type.The allowing of Co-Channel is allowing only in case of Co-Channel configuration.

4.9. Set the ODU configuration data value.

4.9.1. Frequency mode and Tx / Rx frequencies.

Once the IF level is adjusted, it is possible to set the Tx / Rx frequency and power settings.

In order to set the frequency, it is necessary to select in which frequency mode the link will work: Continuous

mode orFreq Plan mode.

In the Continuous mode the frequency value are entered directly in KHz.

In the Freq Plan mode enter the Freq Plan value (Channel ID), preset the values of the first channel IDand last channel ID (see the OMN manual for more info).

Note that the Frequency Plan modality, allows determining the transmission frequency with the number ID of thechannel.To use this modality, it is necessary to define the frequency plan intended to be used.In particular, it is necessary to specify the identifier (numeric) of the first ID and last ID channel intended to beused, the frequency transmission of the first channel and the spacing among the different channels.

Note that, for Frequency RF value, set the proper value, in accordance to the RF bandwidth of ODU andsystem Config.

The RF bandwidth depends to the type of ODU and the Modulation Type (selected from the system config data(32 or 128).For more info see the UMN Manual in the electrical characteristics chapter.

For the Frequency setting, select from the main Status and configuration menu, the ODU configure field.According with the frequency plan select in which frequency mode will work the link, continuous mode or FreqPlan mode.

On the same menu, select the channel spacing according with the planning. Note that this field applies thespacing filter in the ODU but not all the bandwidth. For a properly values refer to the following reference value(except other condition depending to the frequency planning):

28000 Khz for system at one STM-1 and 128 TCM modulation value

55000 Khz for system at one STM-1 and 32 TCM modulation value

56000 Khz for system at two STM-1 and 128 TCM modulation value.

All other value depends to the Frequency planning for network.

In order to execute the properly settings for channel spacing, it is necessary proceed as follows before(in case the frequency mode are in Continuous):

1. Enable the Freq Plan Activation On;2. Set the parameters of the frequency plan: Freq Ch. #1, First Channel ID and Last Channel ID;3. Disable the Freq Plan Activation Off;

Note that if any data for Tx Freq. Plan Parameter are set the system dont accept the related data forChannel spacing setting.

Once described the frequency plan, in order to transmit on a given channel, it is sufficient to write the identifier ofthe chosen channel into the RF Channel ID field.

Set the Frequency parameter for all ODU

Note that for Narrowband ODU the frequency setting is not applicable, the ODU is with a fixed frequencyvalue.

4.11.3. Configuration of Co-Channel operation

The SRA 4 radio equipment allows setting the co-channel operation for the system, only for System Type (2+0).This functionality is supported only by Co-channel Wideband ODU. It is possible to configure each BB-Modem unitto operate with a given polarization at RF frequency: one of the two ODUs will be configured as master sync(synchronization source), while the other ODU will be configured as slave sync (the synchronization source istaken by the other ODU).

In case of co-channel configuration, the transmission frequencies of the two ODUs must be the same(F_TX_ODU1=F_TX_ODU2; F_RX_ODU1=F_RX_ODU2).The equipments with (1+1) FD System Type and enabled co-channel functionality do not protect againstthe selective fading.

The operator must configure one of the two BB-Modem units with a given polarization:the other unit will automatically configured with the orthogonal polarization.A configuration change from alternate polarization to co-channel polarization (in the System Types which supportthis functionality) is refused if:

at least one of the two ODUs is a Narrowband ODU; at least one of the two ODUs does not support the co-channel operation.

It is possible to select the IF/RF synchronization between the ODUs among:

ODU 1 (connected to the upper BB-modem card) master, ODU 2 slave; ODU 2 (connected to the lower BB-modem card) master, ODU 1 slave;

Note that in case of Co-Channel system type, is required a properly IDU cabling connection and ODUsinterconnection cable Kit. For more detail refer to UMN Manual.

4.12. Configuration of the network parameters.

The new IDU coming from factory doesnt have any project specified IP address. A default address was set fromfactory, this address is 10.10.10.10Independently of the local IP Address of equipment, the local connection using the Localne.map file (using thedial-up modem connection) supply the access in all systems; this access is only a local access.After the activation of system is suitable set a specific IP address, in order to manage the equipment from remotestation (after the alignment).

In a stand-alone link scenario it is not necessary to define a complete IP planning, but is suitable to set only twovalid IP addresses:

Use this Net mask on both radios 255.255.255.0 (same value for both stations)

Use this IP address 150.166.X.Y

Suggested IP Address for stands alone Link:

Station A Station B

IP Address 150.166.16.2 150.166.8.4

Net Mask 255.255.255.0 255.255.255.0

The above mentioned rules are only indicative and only for stand alone link, for different rule refer to the IP plan ofproject.In case of stand alone link (without IP network Plan), dont connect any Network cables or other network theequipments (Switch, Hub, Router etc).

Note that never set these IP addresses:

0.x.x.x (network address = 0) 127.x.x.x (addresses reserved to loopback) 192.168.255.x (network addresses 192.168.255) Y.x.x.x con 224

For the Alarm unit replacement procedure, verify before to start this measure, if the system is in the SVR 4.5 orhigher, if the related Plug In SW are matching with the system SVR and if the Alarm controller unit support this

feature.

If the system support this functionality operate with the following procedure:

Pressing the Maintenance push-button in the Equipment Status & Configuration window, the Maintenancewindow opens, where the operator can execute the procedure for the replacing of the alarm unit without trafficloss.

In order that this functionality is supported, it is necessary that at least a BB-modem unit is of the HWversion that supports this procedure and that this BB-modem unit is supplied (Vpow connectorconnected to power supply). Other wise, the Start push-button will remain inactive and the extraction ofthe alarm unit will cause the switching off of the whole IDU and of the ODUs.

Ifthis functionality is supported, push-buttons Key in Plug-in Windows

Press the Start push-button and verify that Switch Status changes from Open to Closed. Extract the hardware key from the alarm unit Extract the front panel from the unit Re-Insert the alarm unit Install the front panel Insert the hardware key.

All the steps must be completed within 3 minutes. Otherwise, the IDU unit, after 3 minutes, switches off.

Check on the BER Instrument that after the simulation of Alarm unit management, the STM1 signal workingproperly.

5.1.3.4. Rx Power Value

At the end of alignment phase, check the received power level from main menu Measurements > View field.

Remember that:

Theoretical Nominal Received Signal: insert the value calculated from the Path calculation (ifavailable).

Readed Received Power: insert the value showed from the LCT SW.

The values of Prx are applicable only in case of normal propagation condition, without interference /fading and with the MW link in complete path clearance.

The value showed on PC has a accuracy at about 3 dB, but is necessary considering same a tolerancefor Ptx Value. Refer to the UMN manual for more indication.

For system 1+1 FD the Rx value must be the same (within the equipment tolerance, indicate in the fieldtest sheets).

For system 1+1 HSTBY with unbalanced Mounting Kit the PRx value for ODU 2 (Stand-By Channel)must be 10 12 dB lower than the ODU 1 (Main) (refer to the mounting frame data sheet).

To optimize the AGC response and detection from the system set a properly value of Channel SpacingData on the ODU configuration.

5.1.4.1. Protection Test

Purpose of this test is checking the switching functionality of system.Apply the Local test in Station A and Station B

Prepare the test bend in figure.


Note that, for HSBY system and system up to 1+1, you have three basic choices:

Note thet the protection scheme which can be used on the SRA 4 equipment are:

(1+1) Hot Stand-by, for the protection against hardware failures of the reception and transmission failures(RF and IF sections)

(1+1) Frequency Diversity, to add a protection also against the unbalancing in the propagation of theradio signal as fading and multipath interferences (the hitless switching is required in the receptionsection)

2x(1+1) Frequency Diversity, it is a protection scheme identical to (1+1), but with two (1+1) independentsystems within the same Network Element.

The window layout and the displayed parameters depend on the System Type configured on theequipment.

For all system up to 1+1 the basic displayed menu are showed in the following figure:

5.1.4.3. ATPC Functional Test

Purpose of this test is checking the functionality of ATPC Feature.

Being a system split, the measure it is feasible with some limitations, it is possible only a functional test.In order to perform a properly ATPC function the link must be installed in laboratory.

SRA 4 equipment supports the ATPC (Automatic Transmit Power Control) function both in HSBY systems and inFD systems.All the processing is executed by the FPGA present on the BB-Modem. The ATPC information is exchangedbetween the far ends via byte S(2,2).Note that the ATPC function has a different implementation between Narrowband ODU and Wideband ODU.Refer to the UMN and OMN manual for more specification.

Pmin and ATPC Range values are set in such a way to respect the hardware range of the transmissionpower values for ODU. The control on these values is executed by ODU that refuses the settings if theyare not correct.The limitations that must be respected are:

Pmin + ATPC_Range less or equal to TX Power max Pmin TX Power min

In order to verify the ATPC feature set in the Tx Power Setting field the ATPC Management value in Enabledstatus. Verify (with a properly value of ATPC Threshold and P-min Start value) if the value of Prx signal changerelated to the threshold value.Return to the value of P-min Start with the nominal Tx power and set the ATPC Management in Disabled status.Verify that the Prx value return with a nominal value.

Note that the Prx value is related to Local Station but the Ptx setting must be change in the remotestation. For more information related the ATPC function refer to the UNM and OMN Manual.

At the end of test set the ATPC status related to the project specification.

Test Instrument mode.

Use the test bench showed in above figure. Set the SDH BER Test instrument with the basic setting parameter for

a STM 1 frame BER Test.

Connect a BER meter on the main radio channel under test.

The test should be done with no errors during a recording time of 2 or 3 hours (suggested short term time forreserve or stand-by channel) and minimal 12 hours (suggested long term time for working or main channel) for thelong term evaluation, the result should be better than 10

-10.

LCT or Netviewer mode.

With the LCT engine 6.0 or Higher (using the properly plug in SW for SRA 4 SVR 4.5 or higher), is possible start ameasure of performance for long period time and showing the related result in a txt format files.

The Commissioning Report application allows displaying and saving to file the report of the measures of the longperiod performances.The measures of the long period performances are generally enabled and collected for maintenance purposesduring the execution of commissioning tests.The long period performances are made by a set of 192 consecutive quarter intervals of performance monitoring(performance G.821/G.826 like, RSPI, RPS).The measures of the long period performances are stored in the non volatile memory of the Controller of the NE.The measures of the long period performances are collected using a XML file incompressed format, which is transferred via FTP when the request arrives from LCT.

To start the test following this two step:

a. Start the Long PM Recording from the specified test menu from the SW applicationb. At the end of the PM Recording apply the Functionality of Commissioning report of system.

Long PM Recording

Pressing the Testing push-buttons in the Equipment Status & Configuration window, the Testing windowopens. Pressing the Long PM Recording field.

On SRA4 there is a command that allows enabling/disabling the recording of the long period performances (bydefault, this recording is disabled).

To define the time window for the recording, it is necessary to configure: Recording Type,defines the the relevant position of the time window: From Start Time o Continuous Mode:

Note that the NE Controller resets the content of the long period performance records:

at start-up;

after a manual reset command;

in correspondence ofStart Time (start of the data recording)

The window displays a counter that shows how many 15 minutes intervals have been already recorded (ExpiredQuarters field).

If the Long PM Recording Start setting is From Start Time, the NE writes a file as soon as it ends to record thelast 15 minutes interval.IfLong PM Recording Start is set to Continuous Mode, the file of the recordings is created on-fly when the FTPrequest is made.

The operator, after the configuration of all the recording parameters, can enable it clicking twice on the LongPeriod PM Recording field: the following Field Editing window opens.

The Get PM Recorded File push-button opens the PMCommReport window for the recording of the long periodperformance file.

Commissioning report

The procedure for the execution of the Commissioning Report is the following one:Run from the plug-in of NE the Commissioning Report tool.

The PmCommReport window opens.

Click on Browse and specify the name of the file and the relevant path where save the report.

Click on Start to transfer via FTP the measures of the long period performances stored into the NE; if a file withthe same name already exists in the folder, a confirmation for overwriting the existing file is required.It is always possible anytime to stop the transfer of the long period performance measures and close the

Commissioning Report tool clicking on Close.During the transfer, the Start and Show push
