Type
The LOS in TS16 is detected on the base of Basic frame synchronization.
= 0: The LOS in TS16 is cleared when 16 consecutive TS16 are not all received as ‘0’.
= 1: The LOS in TS16 is detected when 16 consecutive TS16 are all received as ‘0’.
The AIS in TS16 is detected on the base of Basic frame synchronization.
= 0: The AIS in TS16 is cleared when TS16 contains more than 3 zeros in a 16-consecutive-Basic-frame period.
= 1: The AIS in TS16 is detected when TS16 contains less than 4 zeros in each of two 16-consecutive-Basic-frame periods.
The Remote Signaling Multi-Frame alarm is detected on the base of CAS Signaling Multi-Frame synchronization.
= 0: The Remote Signaling Multi-Frame alarm is cleared when a single Y bit is received as ‘0’.
= 1: The Remote Signaling Multi-Frame alarm is detected when 3 consecutive Y bits are received as ‘1’.
