NAME AND DESCRIPTION
Receive Remote Alarm. Set when bit 3 of timeslot 0 in non-align
frames set for three consecutive non-align frames.
Receive Distant Multiframe Alarm. Set when bit 6 of timeslot 16
in frame 0 is set for three consecutive multiframes.
Receive Signaling All Ones. Set when the contents of timeslot 16
have been all 1's for two consecutive frames.
Receive Unframed All Ones. Set when less than three 0s have
been received in the last two consecutive frames.
Frame Resync Criteria Met. Set when the frame error criteria are
met; also the frame resync is initiated if RCR.1=0.
CAS Multiframe Resync Criteria Met. Set when the CAS
multiframe error criteria are met; also, the frame resync is initiated
if RCR.1=0.
Receive Loss of Sync. Set when resync is in progress.
Error Counter Saturation. Set when any of the on-chip counters
at FECR, CECR or BVCR saturates.
