Optical STM-1 option card test
...................................................................................................................................................................................................................................
Overview
This test verifies whether the installation of the optical STM-1 option card is done
correctly and the proper function by testing the port.
This test includes a BER test for each option card tributary port, and a port alarm test.
Estimated duration
10 minutes.
Remarks
This test is only applicable for 1643 AM NEs with two STM-4 line ports (S42 and
L42). For TM configurations (S4.1 and L4.1) the setup and procedure written in
section “PDH option card test” (p. 7-13) need to be followed, with the exception that
the PDH analyzer needs to be replaced by an SDH analyzer, and the STM1cNES alarm
must be set to
Reported.
Test setup
The following figure illustrates a possible test setup.
Note: Add a 10 dB optical attenuator in both connections between LP1 and LP2.
Start condition
Be sure the following start condition is fulfilled:
• The procedure in section “Preparation and test of the main unit” (p. 7-6) must have
been performed and the test results are correct.
• The ITM-CIT must be connected and logged-in to the NE.
• Test setup as shown in the figure above.
