Parameter
line-number
: T1 channel number in the range of 1 to 28.
local
: Enable local loopback on the T1 channel.
remote
: Enable external remote loopback on the T1 channel.
Description
Using the
t1 set loopback
command, you can enable T1 loopback or configure the
loopback mode of an T1 sub-interface on the T3 interface. Using the
undo t1 set
loopback
command, you can disable T1 loopback.
By default, E1 loopback is disabled.
If the link layer protocol of an E1 channel is PPP and setting loopback on it, it is
normal that the link layer protocol is reported as “DOWN”.
Loopback is usually used for some special detection. It should not be enabled in
normal working condition.

# Enable the local loopback on the first T1 channel of T3 0.
