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, use the following command to perform a test of the DS1 loop
in the fiber direction:
test-trmsn-t1:address:dirn=mux:dur=( );
Where address = address identifier of the DS1 or T1 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.
8. Was the test successful (error free)?
If YES, then proceed to Step 12.
If NO, then proceed to Step 34.
9.
NOTE:
The DS1/DS1PM circuit packs are connected to a DSX-1 cross connect,
T1EXT circuit packs are connected to a T1 interface, and the TMUX
circuit pack is connected to a DSX-3 cross connect.
See Figure 2. At the near-end DSX-1, DSX-3 cross-connection, or T1 interface
associated with the DDM-2000 being tested, connect a patch cord from the
OUT jack to the IN jack for the DS1 or T1 channel to be tested.
10. Use the following command to perform a DS1 transmission test in the demux
direction to test the DS1 loop in the DSX or T1 interface direction:
test-trmsn-t1:address:dirn=demux:dur=( );
Where address = address identifier of the DS1 or T1 signal.
dirn = direction of the test. If dirn=demux, direction is
toward DSX.
dur = duration of the test in minutes (1-120); default is 1.
11. Was the test successful (error free)?
If YES, then continue with Step 12.
If NO, then proceed to Step 34.
