INVERSE MULTIPLEXING OVER ATM
VLDLBEN
The indirect virtual link based diagnostic loopback enable bit (VLDLBEN)
reports the loopback enable flag read from the timeslot provision RAM after
an indirect read operation has been completed. The loopback enable flag to
be written to the timeslot provision RAM in an indirect write operation must be
set up in this register before triggering the write. When VLDLBEN is set high,
the current receive data byte is to be over-written by data retrieved from the
loopback FIFO of the virtual link as indicated by VLINK[2:0]. When VLDLBEN
is set low, the current receive data byte is processed normally. VLDLBEN
reflects the value written until the completion of a subsequent indirect read
operation.
