-1 PRBS pattern. Connect the PDH analyzer to
TP1.1. Start a BER test.

Check if the slot and port number of the ES alarm source corresponds with the physical
position on the ODF to which the optical loop is connected.

Set the Line Ports to “
Monitored
”.

Connect the optical power meter to the fiber returning from the ODF (LP1.1 input) (refer
to
Figure 7-2, “Line port connection to optical distribution frame test” (p. 7-8)
