A CIT is required to make cross-connections for this test.
At the near-end
DDM-2000
, connect the CIT to the
CIT
jack on the User Panel,
if required.

2. If this test is being performed on a shelf that has the
OLIU
s looped back, use
the rtrv-sync and switch-sync:s=
mode
:pri=manual commands to
verify/switch timing mode to
holdover
.
3.
NOTE:
Work orders, office records, or CIT ent-crs-{sts1 or vt1} or
rtrv-crs-{sts1 or vt1} commands may be used to make or verify
cross-connections.
At each shelf in the network, make/verify that proper STS-1/VT1(DS1)
terminating and pass-through cross-connections have been made for each
DS1 circuit being tested, as required.
4. Are you using CIT and test-trmsn-t1 command to perform this test?
If
YES
, continue with
Step 5
.
If
NO
, proceed to
Step 22
.
5.
NOTE:
If one terminating end is equipped with
STS1E
circuit packs to provide
EC-1 service and the other terminating end is equipped with
DS1
,
DS1PM
, or
T1EXT
circuit packs, the DS1 transmission test is performed
from the DS1 terminating end. If the CIT and test-trmsn-t1:
command is being used to perform the test and you are at the EC-1
terminating end, log into the DS1 end to perform the test using the
test-trmsn-t1: command.
See Figures 1 and 2. If local tests are being performed, the fiber loopbacks at
the near-end
OLIU
s must be in place. If end-to-end tests are being performed,
do ONE of the following:
a. Connect a patch cord from the
OUT
jack to the
IN
jack at the far-end
DSX-1, STSX, DSX-3 cross-connection, or T1 interface associated with
the DS1 channel to be tested.
