The channel loop-back is selected by LOOP.ECLB = 1.
Each of the 24 time slots can be selected for loop-back from the system PCM input (XDI)
to the system PCM output (RDO). This loop-back is programmed for one time slot at a
time selected by register LOOP. During loop-back, an idle channel code programmed in
register IDLE is transmitted to the remote end in the corresponding PCM route time slot.
For the time slot test, sending sequences of test patterns like a 1-kHz check signal
should be avoided. Otherwise an increased occurrence of slips in the tested time slot
disturbs testing. These slips do not influence the other time slots and the function of the
receive memory. The usage of a quasi-static test pattern is recommended.
