Bit
Name
Functional Description
7
CRCS1
Receive CRC Error Status One
. If one, the evaluation of the last received submultiframe 1
resulted in an error. If zero, the last submultiframe 1 was error free. Updated on a
submultiframe 1 basis.
6
CRCS2
Receive CRC Error Status Two
. If one, the evaluation of the last received submultiframe 2
resulted in an error. If zero, the last submultiframe 2 was error free. Updated on a
submultiframe 2 basis.
5
RFAIL
Remote CRC-4 Multiframe Generator/Detector Failure
. If one, then 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 alignment has been maintained). If zero, indicates normal operation.
4
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 excess consecutive bit
periods are zero. The threshold for this condition is set by the control bit L32Z. If L32Z is set
high the threshold is 32 successive zeros. If L32Z is set low the threshold is 192 successive
zeros. 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.
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 control bit ASEL.
1
RAIS
Remote Alarm Indication Status
. If one, there is currently a remote alarm condition (i.e.,
received A bit is one). If zero, normal operation. Updated on a non-frame alignment frame
basis.
0
RCRS
RAI and Continuous CRC Error Status
. If one, there is currently an RAI and continuous
CRC error condition. If zero, normal operation. Updated on a multiframe basis.
