6. System Line Up and Commissioning

The Line Up test is a system control in order to verify if all configuration and functionality of equipmentworking properly.

We divide this test in local check and hop check.The local check is fundamentally the control of all setting and local functionality of system (ex. LocalLoop). The hop check is the control of the main Link functionality (system tests).

For Line test use the same testing reported in the “Field commissioning Test Sheets”.

Note that

Note that the Field commissioning tests sheets documents are composed by different protocolsdocuments related to the IDU Type and the Tributary access unit type.

To use the documents correctly, refer to the following table:

Doc Type Description

For the background BER test using the SW application, refer to the OMN manual to properly setting ofquality parameter.

Note that to start a recording from SW is necessary a permanent connection with the PC.It’s also possible from SW to retrieve the status of Link quality in the last 4 Hours (15 minutes step) orin the last 4 day (day by day). In this case the control from equipment is permanent.

The measurements must be done in normal propagation condit ions

Using the SW application, the system perform a analysis using the ITU-T G.826 recommendation.The Rec. G.826 foresees that the calculation of the quality parameters is based upon the counting of

the errored blocks.For the SRAL XD, the frame of the aggregate radio signal (proprietary format) has been madeequivalent with a block.The performance monitoring is executed only on point-point hops and it is realized according to thebase of the direct measurement of the detected “errored blocks”.The performance data are the following ones:

• UAS (Number of Seconds of Unavailability): it provides the unavailability seconds of theconnection into a specified observation period.

• SES (Number of Severely Errored Seconds): it represents the seconds during which it ispresent one of the following conditions:

o percentage of errored blocks equal to or higher than 30%o presence of at least a special event called “defect” (the classification of the “defects”

for the PDH systems is the following one: Loss of Signal (LOS), Alarm Indication

Signal (AIS), Loss of Frame Alignment (LOF)).• ES (Number of Errored Seconds): it represents the seconds during which it is present at least

one errored block.

• BBE (Number of Background Block Errors): it represents the number of errored blocks into anot SES second.

• OI (Number of Outage Intensity): it is the number of unavailability events into a definedobservation interval.

Permanent performance analysis (examplewith quarter steps)

Result of Performance monitoring inMS Excel application

At the end of test fill on the related table the resul of measure. If required attach to the fieldcommissioning report the Excel files of result.

Using the commissioning report application, from LCT SW.

This method is applicable only with engine 6.1 or higher and with a properly SVR of equipment andplugIn SW.

Fundamental is the same result of the performance monitoring (precedent method), but is possibledisconnect the PC from the equipment and download at the end of the test the result.

The test result are compatible with Notepad Windows application (txt), in this case on thecommissioning test sheet is required only the copy and past in the proper table the result.

6.2.7. Testing on ETH port

For ETH port in case of data tributaries card (available only for Plug In IDU) is suggested in field onlya functional tests in order to check the access functionality.

For this test is necessary 2 laptop (one for each station) connected on the ETH port under test.The test consists in:

• Ping test between two computer

• FTP functional test between two computer

For other test (and related tests instrument) refer to the particulars requirement on the projectspecification.

6.2.7.1. Ping test

Purpose of this test is verifying the basic communication between ETH interfaces in both stations.Use the test bench indicate in the next figure:

Station BStation A

On both Laptops, configure a valid IP Address in the same sub network (example 10.10.10.2 and10.10.10.4).

To configure the IP addresses search the properties of ETH card and on the “Internet Protocol(TCP/IP)” properties set the address (with the same Net mask).

Open the windows DOS prompt and write the following command:

ping x.x.x.x where x.x.x.x is the IP address of the remote computer.

If the communication is established there is reply information from the remote PC. Apply the test from station A to B and from B to A.Note that to apply this test is suitable disable the firewall installed on the PC (if there are).
