Implement a Loopback
Put the Line into Loopback
Complete each task to put the line into loopback.
Open a Command Line. Open a different command prompt (again select-
ing Run as administrator). This enables you to monitor the process at the same
time that you implement it.
Check the Line. First, check the line status:
For example:
wanpipemon -i wanpipe1_if1 -c Ta
The display indicates alarms on the line.
Next, check the line’s loopback mode:
The loopback mode should be disabled.
Syntax: wanpipemon -i <interface ID> -c Ta
Replace <interface ID> with the ID that you determined ear-
lier.
Syntax: wanpipemon -i <interface ID> -c Tlb
Replace <interface ID> with the ID that you determined ear-
lier.
