AMI:

The AMI bit enables AMI line coding when set to logic 1; when it is set to logic

0, the HDB3 line coding is enabled.

SIGEN, DLEN:

The SIGEN and DLEN bits select the signaling data source for Time Slot 16

(TS16) as follows:

SIGEN

DLEN

MODE

Signaling insertion disabled. TS16 data is taken

directly from the input BTPCM[x] TS16.

CCS enabled. TS16 data is taken directly from

the TDLSIG[x] input or from the HDLC/LAPD

transmitter.

Reserved.

CAS enabled. TS16 data is taken from either

BTSIG[x] stream or from the TPSC Data Control

byte as selected on a per-timeslot basis via the

SIGSRC bit. The format of the BTSIG[x] input

data stream is shown in the "Functional Timing"

section.
