Loopback Mode
Loopback mode is a transmission state in which the signal
received by the port is returned to the sender. Use this mode
when the remote end (the Telco, for example) is testing your
line; all information sent is returned to the remote end.
Two loopback settings are available:
•
Line loopback—The signal returned to the loopback
command source consists of the full signal. Bit
sequence integrity is maintained. No change in framing
occurs, and no bipolar violations are removed. This is
the default loopback setting.
•
Payload loopback—The signal returned to the loopback
command source consists of the payload of the received
signal and newly-generated ESF framing.
To change the default loopback mode setting:
1.
