DDM-2000 OC-3 MULTIPLEXER
NOTE:
Proper cross-connections must be made at each shelf to establish the
complete end-to-end path for the DS3 circuit being tested. TARP Release
13 and 15 have no default cross-connections and supports only manual
VT1.5 and STS-1 cross-connections. See the description of the following
commands in the Commands and Reports section of this manual:
cnvt-crs, dlt-crs-sts1, dlt-crs-vt1, ent-crs-sts1,
ent-crs-vt1, rtrv-crs-sts1, rtrv-crs-vt1, cnvt-crs-sts1,
set-ne,andrtrv-ne. See Cross-Connection Provisioning in the
Administration and Provisioning section of this manual for more
information on cross-connection provisioning.
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, 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). After the tests are completed, remove the
temporary circuit packs, perform an update, and reinstall the STS1E
circuit packs.
At the near-end DDM-2000, connect the CIT to the CIT jack on the User Panel,
if required.

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