RxSa4ENB
R/W
0
This Read/Write bit is used to specify whether or not data link infor-
mation will be transported via National Bit Sa4 (bit 3 within timeslot 0
of non-FAS frames)
0 = Sa4 does not carry data link information
1 = Sa4 carries data link information
N
OTE: This bit-field is valid only if the RxSIGDL[2:0] = “000” or “001”.
(If the National bits have been configured to carry data link
bits).

These three Read/Write bits are used to specify the type of data that
is to be extracted via D/E channel, National Bits in timeslot 0 of the
non-FAS frames, and Timeslot 16 in the outbound frames.
D/E Channel
0xx = Fractional Output
1xx = Serial Signaling Output
National Bits (Sa4-8
)
000 = Data Link Data extracted from National bits
001 = Data Link Data extracted from National bits
010 = National bits forced to 1, not used to carry data link data
011 = None (forced to 1)
1xx = Data Link Data extracted from National bits
Timeslot 16
000 = Timeslot 16 is taken directly from PCM
001 = CAS Signaling bits A,B,C,D (per time slot)
010 = CCS Signaling bits A,B,C,D
011 = CAS Signaling bits A,B,C,D (per time slot)
1xx = Timeslot 16 is taken directly from PCM
