FAS Sync Active. Set while the synchronizer is searching for
alignment at the FAS level.
CASSA
SSR.1
CAS MF Sync Active. Set while the synchronizer is searching
for the CAS MF alignment word.
CRC4SA
SSR.0
CRC4 MF Sync Active. Set while the synchronizer is searching
for the CRC4 MF alignment word.
CRC4 SYNC COUNTER
The CRC4 Sync Counter increments each time the 8ms CRC4 multiframe search times out. The counter
is cleared when the DS2143 has successfully obtained synchronization at the CRC4 level. The counter
can also be cleared by disabling the CRC4 mode (CCR.0=0). This counter is useful for determining the
amount of time the DS2143 has been searching for synchronization at the CRC4 level. Annex B of
CCITT G.706 suggests that if synchronization at the CRC4 level cannot be obtained within 400 ms, then
the search should be abandoned and proper action taken. The CRC4 Sync Counter will rollover
