1SEC
One Second Timer Status.
This bit
changes state once every 0.5
second and is synchronous with the
2SEC timer.
6
2SEC
Two Second Timer Status.
This bit
changes state once every second
and is synchronous with the 1SEC
timer.

T1
Timer One.
This bit will be high
after a signal has been received,
that
consists
operation frames, and persists for
100 msec. This bit shall be low
when T2 becomes high. Refer to
I.431 Section 5.9.2.2.3.

400T
400 msec. Timer Status.
This bit
changes state when the 400 msec.
CRC-4 multiframe alignment timer
expires.
2
8T
8 msec. Timer Status.
This bit
changes state when the 8 msec.
CRC-4 multiframe alignment timer
expires.

CALN
CRC-4 Alignment.
This bit changes
state every msec. When CRC-4
multiframe alignment has been
achieved state changes of this bit
are synchronous with the receive
CRC-4 synchronization signal.
0
KLVE
Keep Alive.
This bit is high when
the AIS status bit (page 03H,
address 19H) has been high for at
least 100msec. This bit will be low
when AIS goes low (I.431).

RIU1
Receive International Use 1.
This
bit is received on the PCM 30 2048
kbit/sec. link in bit position one of
the non-frame alignment signal. It is
used
for
CRC-4
alignment or international use.

RNFAB
Receive Non-frame Alignment
Bit.
This bit is received on the PCM
30 2048 kbit/sec. link in bit position
two of the non-frame alignment
signal. This bit should be one in
order
to
differentiate
frame alignment frames and non-
frame alignment frames.

RALM
Receive Alarm.
This bit is received
on the PCM 30 2048 kbit/sec. link in
bit position three (the A bit) of the
non-frame alignment signal. It is
used as a remote alarm indication
(RAI) from the far end of the PCM
30 link (1 - alarm, 0 - normal).

RNU4-8
Receive National Use Four to
Eight.
These bits are received on
the PCM 30 2048 kbit/sec. link in bit
positions four to eight (the S
a
bits)
of the non-frame alignment signal.
