Setting Port and Clock Modes

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.Select Loopback mode on the Port Test Configuration dialog box (shown in Figure D-2 on page 165).

2.Click Options on the Line Test Configuration dialog box.

The Port Options dialog box appears:
