Receive Multiframe Alignment Bits
One to Four
. These bits are received
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 bit should be 0000
for
proper

X1
Receive Spare Bit X1
. This bit is
received on the PCM 30 2048 kbit/
sec. link in bit position five of time slot
16 of frame zero of every signalling
multiframe.
2
Y
Receive Y-bit.
This bit is received on
the PCM 30 2048 kbit/sec. link in bit
position six of time slot 16 of frame
zero of every signalling multiframe.
The Y bit may indicate loss of
multiframe alignment at the remote
end (1 -loss of multiframe alignment;
0 - multiframe alignment acquired).

X2, X3
Receive Spare Bits X2 and X3.
These bits are received on the PCM
30 2048 kbit/sec. link in bit positions
seven and eight respectively, of time
slot 16 of frame zero of every
signalling multiframe.

Signal
. If one, indicates that a
valid AIS or all ones signal is
being received. If zero, indicates
that a valid AIS signal is not

AIS detection is determined by
the control bit ASEL.

channel 16. If zero, normal
operation. Updated on a frame

LOSS
Loss of Signal Status
. If one,
indicates the presence of a loss
of signal condition. If zero,
indicates normal operation. A
loss of signal condition occurs
when
192
consecutive
periods are zero. A loss of signal
condition terminates when an
average ones density of at least
12.5% has been received over a
period of 192 contiguous pulse
positions starting with a pulse.

AUXPS
Auxiliary Pattern Status
. This
bit goes high when a continuous
101010... bit stream (Auxiliary
Pattern) is received on the PCM
30 link for a period of at least 512
bits. If zero, auxiliary pattern is
not being received. This pattern
will be decoded in the presence
of a bit error rate of as much as
10-3.

MFALMS
Multiframe Alarm Status
. This
bit goes high in the event of
receipt of a multiframe alarm. It
goes low when the received
multiframe alarm bit goes low.
