22. See Figure 1. If local tests are being performed, the fiber loopback at the
near-end
OLIU
must be in place. If end-to-end tests are being performed, at
the far-end DSX-1, STSX cross-connect point, or T1 interface associated with
the DDM-2000 being tested, connect a patch cord from the
OUT
jack to the
IN
jack for the DS1 channel to be tested.
23. At the near-end DDM-2000 cross-connect point, connect the DS1 test set to
the
IN
and
OUT
jacks associated with the circuit under test.
24. Use the DS1 test set to test for error-free transmission.
25. Was the test successful (error free)?
If
YES
, continue with
Step 26
.
If
NO
, proceed to
Step 36
.
26. Is this first service being placed on the group and is protection circuit pack
installed?
If
YES
, continue with
Step 27
.
If
NO
, proceed to
Step 31
.
27. Unseat the service
DS1
,
DS1PM
, or
T1EXT
circuit pack associated with the
circuit under test.
28. Repeat the DS1 transmission test with the DS1 test set.
29. Was the test successful (error free)?
If
YES
, continue with
Step 30
.
If
NO
, proceed to
Step 36
.
30. Reseat the
DS1
,
DS1PM
, or
T1EXT
circuit pack associated with the circuit
under test.
31. The
DS1
circuit under test has passed the DS1 transmission test. Remove the
looping patch cords from the cross-connections.
32. At the near-end (and the far-end) DDM-2000, momentarily depress the
UPD/INIT
button on the
SYSCTL
to update the
SYSCTL
.
