to use C-bit framing.
Use to enable or disable the router's ability to enter into a loopback initiated by
a remote device connected on a channelized T3 interface.
Specify one of the following loopback options:
customer Enables the router to enter into loopback when it receives an
appropriate signal from the remote interface
network Disables the router's ability to enter into loopback when it receives
an appropriate signal from the remote interface
