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. All ones are inserted into the DS0 channels allocated to that port.
