Perform DS3 Transmission Test
1.
NOTE:
This procedure may be used to perform DS3 transmission tests in the
mux
(toward the fiber) or
demux
(toward the DSX ) direction. When this
procedure is being used to perform end-to-end DS3 tests, it is assumed
that the complete end-to-end system has already been tested and that
only a particular DS3 channel is being tested at this time. Transmission
tests in the
mux
direction may be local or end-to-end tests (See Figure 1).
Transmission tests in the
demux
direction are local cross-connect tests
User/Service Manual, under TEST-TRMSN-T3, gives an explanation of
commands.
NOTE:
This test can be performed either with a CIT and the automated test
command test-trmsn-t3 or with a DS3 test set or M13 test set.
NOTE:
When this procedure is used to do end-to-end tests, one DDM-2000 shelf
will be referred to as the near end and the other shelf as the far end.
These designations are arbitrary; either shelf can be the near-end or the
far-end shelf.
NOTE:
Proper cross-connections must be made at each shelf to establish the
complete end-to-end path for the DS3 circuit being tested. Release 3.0
has no default cross-connections and supports only manual VT1.5
cross-connections. Release 3.1 and later has 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 User/Service Manual:
dlt-crs-vt1, dlt-crs-sts1, ent-crs-vt1, ent-crs-sts1,
rtrv-crs-vt1, rtrv-crs-sts1, set-ne, and rtrv-ne. See
Cross-Connection Provisioning
in the "Administration and Provisioning"
section of this User/Service Manual for more information on
cross-connection provisioning.
NOTE:
A CIT is required to make cross-connections for this test.
Is a CIT available?.
If YES, continue with Step 2.
If NO, proceed to Step 3.
