2. NOTE:
If one terminating end is equipped with STS1E circuit packs to provide
EC-1 service and the other terminating end is equipped with DS3 circuit
packs, the DS3 transmission test is performed from the DS3 terminating
end. If the CIT and
test-trmsn-t3:
command is being used to
perform the test and you are at the EC-1 terminating end, the
rlgn
command may be used to log into the DS3 end to perform the test using
the
test-trmsn-t3:
command.
NOTE:
When both terminating ends are equipped with STS1E circuit packs,
either DS1 or DS3 transmission tests may be performed. For DS3 tests,
one end may be temporarily equipped with DS3 circuits packs to perform
the transmission tests. To perform transmission tests for this
configuration, remove the STS1E at the near end, perform an update
(
upd
), and install the DS3 circuit pack(s). This configuration may only be
tested in the MUX direction. After the tests are completed, remove the
temporary circuit packs, perform an update, and reinstall the STS1E
circuit packs.
NOTE:
If one terminating end is equipped with TMUX circuit packs to provide for
bidirectional termination of one M13 or C-bit formatted DS3 signal and
the other terminating end is equipped with DS1/DS1PM circuit packs,
either DS1 or DS3 transmission tests may be performed. For DS3 tests,
both ends may be temporarily equipped with TMUX circuits packs to
perform the transmission tests. To perform transmission tests for this
configuration, remove the DS1 circuit packs at the far end, perform an
update (
upd
), and install TMUX circuit pack(s). This configuration may
only be tested in the MUX direction. After the tests are completed,
remove the temporary circuit packs, perform an update, and reinstall the
DS1/DS1PM circuit packs.
At the near-end DDM-2000, connect the CIT to the CIT jack on the User Panel,
if required.

3. NOTE:
Work orders, office records, or CIT
ent-crs-sts1
or
rtrv-crs-sts1
commands may be used to make or verify STS-1 cross-connections.
At each shelf in the network, make/verify that proper STS-1 cross-connections
have been made for each DS3 channel being tested.
