Receive Signaling All Ones. Set when the contents of time slot 16 contains fewer
than three zeros over 16 consecutive frames. This alarm is not disabled in the
CCS signaling mode. Both RSA1 and RSA0 are set if a change in signaling is
detected.
Receive Distant MF Alarm. Set when bit 6 of time slot 16 in frame 0 has been set
for two consecutive multiframes. This alarm is not disabled in the CCS signaling
mode.
Receive Signaling All Zeros. Set when over a full MF, time slot 16 contains all
zeros. Both RSA1 and RSA0 are set if a change in signaling is detected.
Receive 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
RTIP and RRING.
Receive Remote Alarm. Set when a remote alarm is received at RTIP and
RRING.
Receive Carrier Loss. Set when 255 (or 2048 if CCR2.1 = 1) consecutive zeros
have been detected at RTIP and RRING.
Receive Loss of Sync. Set when the device is not synchronized to the receive E1
stream.
