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 signalling data source for Time Slot 16
(TS16) as follows:
SIGEN DLEN MODE
0
0
Signalling insertion disabled. TS16 data is taken
directly from the input BTPCM TS16.
0
1
CCS enabled. TS16 data is taken directly from the
TDLSIG input or from the HDLC transmitter.

1
Reserved.
CAS enabled. TS16 data is taken from either BTSIG
stream or from the TPSC Data Contol byte as selected
on a per timeslot basis via the SIGSRC bit. The
format of the BTSIG input data stream is PMC
compatible.
When channel associated signalling (CAS) is enabled, the format of the input
BTSIG stream is selected by the DLEN bit. A logic 1 in the DLEN bit position
selects the PMC compatible format in which the BTSIG stream contains the
PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS’ INTERNAL USE
