Bit 4 = Battery. 1 = Fail
Bit 5 = RAM and ROM alarm flag. 1 = Fail
Bits 6 and 7 = Spares
Bit 0 = M&C processor fault 1 = Fail
Bit 1 = U IO card present alarm 1 = Fail, reserved in
RCS10/10L mode
Bit 2 = IF card present alarm 1 = Fail
Bits 3 - 7 = Spares
Bit 0 = Backward Alarm 1 IDR and IBS
Bit 1 = Backward Alarm 2 IDR only
Bit 2 = Backward Alarm 3 IDR only
Bit 3 = Backward Alarm 4 IDR only
Bits 4 - 7 = Reserved
0 = No, 1 = Yes

Bytes 1 - 2 = Binary value Raw BER 896 = 8.96
Bytes 1 - 2 = Binary value corrected BER
Binary value, 1 decimal point implied 700 = 7.00
Binary value, 1 Hz steps
Bytes 1 - 2 = Binary value test 2047 BER

Bit 0 = Raw BER and corrected BER status. 1 = Valid
Bit 1 = Test 2047 BER status. 1 = Valid
Bits 2 - 3 = EbNo status, 0 = EbNo is invalid, 1 = EbNo is valid,
2 = EbNo is smaller than indicated, value, 3 = EbNo is greater
than indicated value
Bit 4 = BER Counter Overflow. 1 = Overflow Condition
Bit 5 = Test 2047 BER Counter Overflow 1 = Overflow
