NOTE:
For configurations not shown in the examples, local procedures should
be developed to test the DS3 circuits being equipped. A sketch of the
network may need to be made and the paths to be tested should be
determined as shown in the examples in this procedure.
Use the necessary switch commands to set up the DS3 path being tested. [For
example, if the configuration looks like Figure 3, use the
switch-path-sts1:
command for test 1 to make Ring 1 active at both
terminating nodes and all DDM-2000 DRI nodes. Other DS3 path tests for the
same configuration would be set up as follows (Figures 4 through 6)]:
5. Are you using CIT and
test-trmsn-t3:
command to perform this test?
If YES, then continue with Step 6.
If NO, then proceed to Step 23.
6. Are you doing this test in the mux or demux direction?
If MUX direction, then continue with Step 7.
If DEMUX direction, then proceed to Step 9.
7. At the near end DDM-2000, use the following command to perform a test of
the DS3 loop in the fiber direction:
test-trmsn-t3:address:dirn=mux:dur=( );
Where
address
" = address identifier of the DS3 signal.
dirn = direction of the test. If
dirn=mux
, direction is toward
fiber.
dur = duration of the test in minutes (1-120), default is 1.
