The digital loopback loops the received digital time slot (DS0) from the receive
data line to the transmit data line. Signal settings in the configurator do not
affect the loopback. The analog loopback is a full SLAC loopback which loops
the receive analog channel to the transmit analog channel and includes the
affects of the attenuation, impedance, and cable equalization settings.
