Functional Description
7 - 6
RxTS1-0
Receive Time Slot. The two least sig-
nificant bits of a five bit counter that
indicates the number of time slots
between the ST-BUS frame pulse
and E8Ko.
5 - 3
RxBC2 -0
Receive Bit Count. A three bit
counter that indicates the number of
bits between the ST-BUS frame
pulse and E8Ko.
2 - 0
RxEBC2 -0 Receive Eighth Bit Count. A three bit
counter that indicates the number of
one eighth bit times there are
between the ST-BUS frame pulse
and E8Ko. These least significant
bits are valid only when the device is
clocked at 4.096 MHz. The accuracy
of the this measurement is approxi-
mately + 1/16 (one sixteenth) of a bit.

CRCS1
Receive CRC Error Status One. If
one, the evaluation of the last
received submultiframe one resulted
in an error. If zero, the last submulti-
frame one was error free. Updated
on a submultiframe one basis.
6
CRCS2
Receive CRC Error Status Two. If
one, the evaluation of the last
received submultiframe two resulted
in an error. If zero, the last submulti-
frame two was error free. Updated on
a submultiframe two basis.
5
RFAIL
Remote CRC-4 Multiframe Genera-
tor/detector Failure. If one, each of
the previous five seconds have an
E-bit error count of greater than 989,
and for this same period the receive
RAI bit was zero (no remote alarm),
and for the same period the SYNC bit
was equal to zero (basic frame align-
ment has been maintained). If zero,
indicates normal operation.
Table 58 - Alarm Status Word One
4
LOSS
Loss of Signal Status Indication. If
one, indicates the presence of a loss
of signal condition. If zero, indicates
normal operation. A loss of signal
condition occurs when there is an
absence of the receive PCM 30 sig-
nal for 255 contiguous pulse (bit)
positions from the last received
pulse. A loss of signal condition ter-
minates when an average ones den-
sity of at least 12.5% has been
received over a period of 255 contig-
uous pulse positions starting with a
pulse.
3
AIS16S
Alarm Indication Signal 16 Status. If
one, indicates an all ones alarm is
being received in channel 16. If zero,
normal operation. Updated on a
frame basis.
2
AISS
Alarm Indication Status 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
being received. The criteria for AIS
detection is determined by the con-
trol bit ASEL.
1
RAIS
Remote Alarm Indication Status. If
one, there is currently a remote alarm
condition. If zero, normal operation.
Updated on a non-frame alignment
frame basis.
0
RCRS
RAI and Continuous CRC Error Sta-
tus. If one, there is currently an RAI
and continuous CRC error condition.
If zero, normal operation. Updated on
a submultiframe basis.
