Description

Syntax Description
portlist
inband
Default
By default, loopback detection is off.
Usage Guidelines
When inband loopback detection is enabled, a specific sequence of data in the signal payload from the
remote end of the T1 link will cause the local end to enter network line loopback mode and send any
received signal back to the remote end.
Inband loopback detection is only possible if facility data link (FDL) is enabled and configured as
"ATT". See the command "config ports t1 fdl" on page 1330 for more information.
Example
The following command enables inband loopback detection:
config ports 4:1-4:2 t1 lbdetect inband
