DS3 Verification Procedure
The activity in the following procedure is performed from the CO location. Perform
this procedure on all DS3 circuit packs installed.
1. At the CO, change the DS3 violation monitoring mode from VMR to VM by
entering the following command:
set-t3:all:md=cc;
2. Establish a remote login from the CO to the RT site, using the
rlgn-tid
command.
3. Change the violation monitoring mode from VMR to CC in the same man-
ner as at the CO (Step 1).
4. Perform a DS3 or EC-1 loopback on all DS3/EC-1 groups at the RT by issu-
