Line port connection to optical distribution frame test
Overview
This test checks the connections of the optical (STM-1 or STM-4) Line Ports. The correct
labeling on the ODF is checked by monitoring the source of the reported alarm. The
quality of the physical optical connections to the ODF is checked by measuring the
optical power and by performing a receiver sensitivity test.
Estimated duration
10 minutes per port

The following figure illustrates a possible test setup:
Procedure
Proceed as follows to perform the test:
...................................................................................................................................................................................................
1
Provision a cross-connection from the first tributary port TP1.1 to Line Port 1.
...................................................................................................................................................................................................
2
Set the Line Ports to “
Not Monitored
”.
...................................................................................................................................................................................................
3
Set the Alarm Reporting/Severity of STM*cES (STM* ot Expected Input Signal)
alarm from reported “o” to “
Yes
”. (* stands for “1” or “4”, depending on the port type
under test).
...................................................................................................................................................................................................
4
Install a fiber loop on LP1.1 on the ODF.
