Receive LAPD Control
These bits select which one of the three Receive LAPD controller will be
configured to use D/E time slot (Octets 0-23) for receiving LAPD messages.
NOTE: All three LAPD Controller can use D/E timeslots for receiving LAPD
messages. However, only LAPD Controller 1 can use datalink for
reception.
NOTE: Register 0xn360 represents D/E time slot 0, and 0xn377 represents
D/E time slot 23.

The RxDE[1:0] bits in the Receive Signaling
and Data Link Select Register (RSDLSR -
Address - 0xn10C) determine the data
source for Receive D/E time slots.

Receive LAPD Controller 3
RXZERO[1:0]
TYPE OF ZERO CODE SUPPRESSION
SELECTED
00
No zero code suppression is used
01
AT&T bit 7 stuffing is used
10
GTE zero code suppression is used. If GTE
zero code suppression is used, bit 8 is
stuffed in non-signaling frame. Otherwise,
bit 7 is stuffed in signaling frame if signaling
bit is zero.
11
DDS zero code suppression is used. The
value 0x98 replaces the input data
