SR1.7
Receive Signaling All Ones.
Set when the contents of timeslot
16 contains less than three 0s over 16 consecutive frames. This
alarm is not disabled in the CCS signaling mode.
Receive Distant MF Alarm.
Set when bit 6 of timeslot 16 in
frame 0 has been set for two consecutive multiframes. This
alarm is not disabled in the CCS signaling mode.
Receive Signaling All 0s.
Set when over a full MF, timeslot 16
contains all 0s.
Receive Side Elastic Store Slip.
Set when the elastic store has
either repeated or deleted a frame of data.
Receive Unframed All Ones.
Set when an unframed all ones
code is received at RPOS and RNEG.
Receive Remote Alarm.
Set when a remote alarm is received at
RPOS and RNEG.
Receive Carrier Loss.
Set when 255 consecutive 0s have been
detected at RPOS and RNEG.
Receive Loss of Sync.
Set when the device is not synchronized
to the receive E1 stream.
