5. NOTE:
If one terminating end is equipped with STS1E circuit packs to provide
EC-1 service and the other terminating end is equipped with
DS1/DS1PM or T1EXT circuit packs, the DS1 transmission test is
performed from the DS1 terminating end. If the CIT and
test-trmsn-t1: command is being used to perform the test and you
are at the EC-1 terminating end, log into the DS1 end to perform the test
using the test-trmsn-t1: command.
NOTE:
When both terminating ends are equipped with STS1E circuit packs, one
end may be temporarily equipped with either DS1/DS1PM or DS3 circuits
packs and the procedures of DLP-510 or DLP-511 used to perform the
transmission tests.
NOTE:
Local tests cannot be performed in the DEMUX direction for STS1E
circuit packs.
NOTE:
If one terminating end is equipped with a TMUX circuit pack to provide for
bidirectional termination of one M13 or C-bit formatted DS3 signal and
the other terminating end is equipped with DS1/DS1PM or T1EXT circuit
packs, the DS1 transmission test can be performed from the DS3
terminating end using the test-trmsn-t1: command after using the
opr-lpbk-t1: command at the far end equipped with DS1/DS1PM or
T1EXT circuit packs to loop back the test signal. The DS1 transmission
test can also be performed from the DS1 terminating end using the
test-trmsn-t1: command after using the opr-lpbk-t3: command
at the far end equipped with a TMUX circuit pack to loop back the test
signal.
See Figures 1 and 2. If local tests are being performed, the fiber loopbacks at
the near-end OLIUs must be in place. If end-to-end tests are being performed,
do ONE of the following:
a. Connect a patch cord from the OUT jack to the IN jack at the far-end
DSX-1, STSX, DSX-3 cross-connection or T1 interface associated with
the DS1 channel to be tested.
b. Use the rlgn command to log in to the far-end shelf and use the
opr-lpbk-t1:address, opr-lpbk-ec1:address, or
opr-lpbk-t3:address command to loop back the DS1, EC-1, DS3, or
T1 port(s) at the far end. Use logout or toggle (ctrl t) command to
return control of CIT to near end.
