Set Loopback Mode drop-down list, then clicking . Note
that the Alarm State color changes accordingly.
Selecting Network loopback allows the service provider to test
the T1 circuit.
Selecting Payload loopback allows the service provider to test
both the circuit and the T1 Gateway’s ability to encode and
decode the T1 data.

to cancel any loopback test mode.
Be sure to cancel loopback testing so that telephone calls
can again occur.
