The illegal pointer justification request (ILLJREQ) signal is set high when a positive and/or
negative pointer adjustment is received within three frames of a pointer justification event
(inc_ind, dec_ind) or an NDF triggered active offset adjustment (NDF_enable). This bit is
only valid for master timeslots. It is not valid for slave (concatenated) timeslots.
The CONCAT bit is set high if the H1 and H2 pointer bytes received matches the
concatenation indication (one of the five NDF_enable patterns in the NDF field, don't care in
the size field, and all-ones in the pointer offset field).
The discontinuous change of pointer alignment (DISCOPA) signal is set high when there is a
pointer adjustment due to receiving a pointer repeated three times. This bit is only valid for
master timeslots. It is not valid for slave (concatenated) timeslots.
