RxSa8ENB
R/W
0
This Read/Write bit is used to specify whether or not data link information will
be transported via National Bit Sa8 (bit 7 within timeslot 0 of non-FAS frames)
0 = Sa8 does not carry data link information
1 = Sa8 carries data link information
N
OTE
:
This bit-field is valid only if the RxSIGDL[2:0] = “000” or “001”. (The
National bits have been configured to carry data link bits).

RxSa7ENB
R/w
0
This Read/Write bit is used to specify whether or not data link information will
be transported via National Bit Sa7 (bit 6 within timeslot 0 of non-FAS frames)
0 = Sa7 does not carry data link information
1 = Sa7 carries data link information
N
OTE
:
This bit-field is valid only if the RxSIGDL[2:0] = “000” or “001”. (The

RxSa6ENB
R/W
0
This Read/Write bit is used to specify whether or not data link information will
be transported via National Bit Sa6 (bit 5 within timeslot 0 of non-FAS frames)
0 = Sa6 does not carry data Link information
1 = Sa6 carries data link information

RxSa5ENB
R/W
0
This Read/Write bit is used to specify whether or not data link information will
be transported via National Bit Sa5 (bit 4 within timeslot 0 of non-FAS frames)
0 = Sa5 does not carry data link information
1 = Sa5 carries data link information

RxSa4ENB
R/W
0
This Read/Write bit is used to specify whether or not data link information 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

RxSIGDL(2)
R/W
0
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
