6. Are you doing this test in the mux or demux direction?
If
MUX
direction, continue with
Step 7
.
If
DEMUX
direction, 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/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
, proceed to
Step 12
.
If
NO
, proceed to
Step 36
.
9.
NOTE:
The
DS1/DS1PM
circuit packs are connected to a DSX-1 cross connect
and
T1EXT
circuit packs are connected to a T1 interface.
See Figure 2. At the near-end DSX-1 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 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 direction:
test-trmsn-t1:
address
:dirn=demux:dur=( );
Where
address
= address identifier of the DS1/T1 signal.
dirn = direction of the test. If dirn=demux, direction is
toward DSX or T1 interface.
dur = duration of the test in minutes (1-120); default is 1.
11. Was the test successful (error free)?
If
YES
, continue with
Step 12
.
If
NO
, proceed to
Step 36
.
