NOTE:
Local tests cannot be performed in the DEMUX direction for STS1E
circuit packs.
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 or STSX cross-connection associated with the DS1 channel
to be tested.
b. Log into the far-end terminal and use the opr-lpbk-t1:address
or opr-lpbk-ec1:address command to loop back the DS1 or
EC-1 port(s) at the far end. Use logout or toggle (ctrl t) command
to return control of CIT to near end.
