monitoring the received data stream. If there are any framing bit errors,
CAS Multi-Frame alignment pattern errors, CRC Multi-Frame alignment
pattern errors or CRC errors, the Frame Processor will indicate these
errors. The status of loss of frame, loss of Signaling Multi-Frame and
loss of CRC Multi-Frame can also be detected and declared based on
user-selectable criteria. A software reset can also make the Frame Pro-
cessor reframe.
output the extracted data on a separate pin. The Frame Processor also
extracts the contents of the International bits (from both the FAS and the
NFAS frames), the National bits and the Extra bits (from TS16 in the
frame 0 of the Signaling Multi-Frame), and stores these data in registers.
The CRC Sub Multi-Frame alignment 4 bit codeword in the National bit
positions Sa4 to Sa8 can also be extracted and stored in registers, and
updated every CRC Sub Multi-Frame.

Remote Alarm and Remote Signaling Multi-Frame Alarm can be indi-
cated if the corresponding bit has been a certain logic for 1 or 4 consec-
utive times. The AIS (Alarm Indication Signal) Alarm can also be
detected. The Frame Processor can also declare a Red Alarm if the out-
