Description
Facility Alarm Condition Indication (FACI).
A 1 indicates a facility alarm occurred (go read SR1).
Remote Alarm Condition (RAC).
A 1 indicates a remote alarm occurred (go read SR2).
Facility Alarm Event (FAE).
A 1 indicates a facility alarm occurred (go read SR3 and SR4).
PAC Diagnostic Event (PACDE).
A 1 indicates a PAC system event occurred (go read SR5).
Transmit Signaling Superframe Event (TSSFE).
A 1 indicates the transmission of a MOS (or CCS for
CEPT) superframe block has been transmitted and the transmit signaling data buffers are ready for new
data.
Receive Signaling Superframe Event (RSSFE).
A 1 indicates a MOS (or CCS for CEPT) superframe
block has been received and the receive signaling data buffers must be read.
Excessive CRC Error (ECE).
A 1 indicates the receive framer detected an excessive CRC error
condition. The ESF threshold is 32 out of 33 errored CRC checksum blocks. The CEPT threshold is 915
out of 1000 errored CRC checksum blocks.
This Bit Is Reserved and Set to 0.
