LLOS
LIU Loss of Signal indication
. This
bit will be high if the received signal is
below the threshold selected by ELOS
(page 2, address 10H) for a period of
at least 1 msec. This bit will be low for
normal operation.

JACS
Jitter Attenuated Clock Slow
. If one it
indicates that the dejittered clock
period is increased by 1/16 UI. If zero
the clock is at normal speed.

JACF
Jitter Attenuated Clock Fast
. If one it
indicates that the dejittered clock
period is decreased by 1/16 UI. If zero
the clock is at normal speed.

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 multiframe alignment or
international use.
6
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
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).
4-0 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 Sa bits) of
the non-frame alignment signal.
