Force Resynchronization
A transition from low to high initiates a resynchronization procedure
of the pulse frame and the CRC-multiframe (if enabled via bit
FMR2.RFS1) starting directly after the old framing candidate.
Note:FRS is not reset automatically.
Only double violations are detected.
Extended code violation detection: 0000 strings are detected
additionally. Thereafter, next increment of Code Violation
Counter CVC is done after receiving additional four zeros.
The AIS alarm is detected according to ETS300233.
Detection: An AIS alarm is detected if the incoming data stream
contains less than 3 zeros within a period of 512 bits and a Loss
of Frame Alignment is indicated.
Recovery: The alarm is cleared if 3 or more zeros within 512
bits are detected or the FAS word is found.
The AIS alarm is detected according to ITU-T G.775
Detection: An AIS alarm is detected if the incoming data stream
contains for two consecutive doubleframe periods (1024 bits)
less than 3 zeros for each doubleframe period (512 bits).
Recovery: The alarm is cleared if within two consecutive
doubleframe periods 3 or more zeros for each period of 512 bits
are detected.
