CSYN
CRC-4 Synchronization.
If zero,
basic
CRC-4
processing is activated, and TIU0
bit and TIU1 bit programming will
be overwritten. If one, CRC-4
synchronization is disabled, the
first bits of channel 0 are used as
international use bits and are
programmed by TIU0 and TIU1.

AUTC
Automatic CRC-interworking.
If
zero, automatic CRC-interworking
is activated. If one, it is deactivated.
See Framing Algorithm section for
a detail description.

TIU1
Transmit International Use One.
When CRC-4 operation is disabled
(CSYN=1), this bit is transmit on the
PCM 30 2048 kbit/sec. link in bit
position one of time-slot zero of
non-frame-alignment frames. It is
reserved for international use and
should normally be kept at one. If
CRC processing is used, i.e., CSYN
=0, this bit is ignored.

TALM
Transmit Remote Alarm
. This bit is
transmitted on the PCM 30 2048
kbit/sec. link in bit position three (A
bit) of time slot zero of NFAS
frames. It is used to signal an alarm
to the remote end of the PCM 30
link (one - alarm, zero - normal).
This control bit is ignored when
ARAI is zero (page 01H, address
11H).

These bits are

TMA1-4
Transmit Multiframe Alignment
Bits One to Four.
These bits are
transmitted on the PCM 30 2048
kbit/sec. link in bit positions one to
four of time slot 16 of frame zero of
every signalling multiframe. These
bits are used by the far end to
identify specific frames of a
signalling multiframe. TMA1-4 =
0000 for normal operation.

X1
This bit is transmitted on the PCM
30 2048 kbit/sec. link in bit position
five of time slot 16 of frame zero of
every multiframe. X1 is normally
set to one.
2
Y
This bit is transmitted on the PCM
30 2048 kbit/sec. link in bit position
six of time slot 16 of frame zero of
every multiframe. It is used to
indicate the loss of multiframe
alignment to the remote end of the
link. If one - loss of multiframe
alignment; if zero - multiframe
alignment acquired. This bit is
ignored when AUTY is zero (page
01H, address 11H).
