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
(See Figure 2). The Commands and Reports section of this 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. TARP Release
13.0 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
manual:
cnvt-crs
,
dlt-crs-sts1
,
dlt-crs-vt1
,
ent-crs-sts1
,
ent-crs-vt1
,
rtrv-crs-sts1
,
rtrv-crs-vt1
,
set-ne
, and
rtrv-ne
. See Cross-Connection Provisioning in the Administration and
Provisioning section of this manual for more information on
cross-connection provisioning.
NOTE:
A CIT is required for this test if manual cross-connections have to be
made at any shelf.
Is a CIT available?
If YES, then continue with Step 2.
If NO, then proceed to Step 3.
