PDH option card test
...................................................................................................................................................................................................................................
Overview
This test verifies that the option card has been installed properly and that its function is
correct.
If a DDF is applicable then the cabling and connections of the option card ports with
complementary wiring is tested according to the site depending information, and the
port labeling is tested on the DDF whether it matches the correct port number.
This test includes a BER test for each option card tributary port, and a port alarm test.
Estimated duration
20 minutes.
Remarks
If the installation includes a DDF then the interface test must be done from the DDF.
For 1.5 Mbit/s (DS1) and 45 Mbit/s (DS3) ports: since the pulse shape for these
signals is defined at the DDF, the cable length between the port and the DDF can be
compensated for each port output (menu: Port Provisioning, Cable length). By default
the cable compensation is set to 0-131 feet (DS1) or 0-120 feet (DS3). In this test the
PDH analyzer receiver will deal with the cable loss, only because it is connected close
to the DDF. However for each port the length between port and DDF should be
estimated and compensated by selecting the proper length range before the other side is
connected.
Test setup
The following figure illustrates a possible test setup.
Note: For a long haul laser (L11, L12, L41 or L42) a 10 dB attenuator with applicable
connector is required in the loop
