NEWPTR:
The new pointer (NEWPTR) signal is set high when an incoming pointer satisfying the
new_point indication is received.
This bit is only valid for RHPP STS-1/STM0 #1.
ILLJREQ:
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 RHPP STS-1/STM0 #1.
CONCAT:
The CONCAT bit is set high if the H1, H2 pointer byte 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).
