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 top-level menu screen, select Test.
2. From the Test screen, select Lpbk.
3. From the Loopback screen, press the key until the DCLB selection
appears on the screen.
4. Select DCLB.
