Parameters
line-number: Specifies a T1 line number in the range of 1 to 28.
local: Enables internal loopback.
payload: Enables payload loopback mode.
remote: Enables external loopback.
Usage guidelines
Loopback is intended for testing only. Disable the feature when the interface is operating correctly.
If a T1 line encapsulated with PPP is in loopback mode, the state of the link layer protocol is reported as
down.
Examples
# Enable internal loopback on T1 line 1 on T3 2/4/0.
<Sysname> system-view
[Sysname] controller t3 2/4/0
[Sysname-T3 2/4/0] t1 1 loopback local
t1 sendloopcode
Use t1 sendloopcode to set the loopback mode of a far-end T1 line.
Use undo t1 sendloopcode to remove the corresponding setting.

inband-line-up }
undo t1 line-number sendloopcode { fdl-ansi-line-up | fdl-ansi-payload-up | fdl-att-payload-up |
