CAUTION:
Execution of switch commands may affect service. Check local
procedures before performing switch commands.
NOTE:
If this transmission test is to be performed for each path in the end-to-end
network, the switch-path-sts1: or switch-path-vt1: command
must be used at some of the DDM-2000 nodes to switch paths for each
test. If FT-2000 is part of the network, the FAULT-Switch-Path-STS3
command must be used at the FT-2000 Primary DRI node(s) if the
FT-2000 secondary path and the DDM-2000 DRI connections to the
FT-2000 secondary node are to be tested. Up to four tests may have to
be performed for each DS1 circuit if all protection paths are required to be
tested. See Figures 3 through 14.
NOTE:
For configurations not shown in the examples, local procedures should
be developed to test the DS1 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 DS1 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 DS1 path tests for the
same configuration would be set up as follows (Figures 4 through 6)]:
5. Are you using CIT and test-trmsn-t1: 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.
