Starting a Data Channel Loopback

The Data Channel Loopback command (DCLB) loops the data received from the network interface, for all DS0 channels allocated to the selected port, back to the network. The loopback occurs after the data passes through the port circuitry but before it is sent out the data port.

"Procedure

To perform a Data Channel loopback:

1.From the Main Menu screen, select Test.

2.From the Test screen, select Sync Data Port Tests.

3.In the Port field (near the top of the screen), enter either 1 or 2 depending on the synchronous data port that you want to test.

4.For the Data Channel Loopback command (under Local Loopbacks), select Start.
