LOSS OF FRAME
NI unable to frame align with incoming FAS/NFAS framing pattern.
Remote Alarm (Bit 3 of NFAS word) is transmitted out the network
interface.
LOSS OF TS16 MF
NI unable to sync on TS16 multiframe signal. Valid only when CAS/
TS16 framing enabled. Remote Multiframe Alarm is transmitted out
the network interface.
LOSS OF CRC-4
NI unable to sync on CRC-4 multiframe signal. Valid only when CRC-
4 framing is enabled. Remote Alarm is transmitted out the network
interface.
AIS RECEIVED
Unframed ones being received at network interface.
TS16 AIS RCVD
Unframed ones being received in TS16 on network interface. Remote
Multiframe Alarm transmitted out network interface.
REMOTE ALARM
Remote alarm signal (Bit 3 of NFAS word) being received at
network interface.
REMOTE MF ALARM
Remote multiframe alarm signal (Bit 6 of TS16 for three consecutive
multiframes) being received at network interface.
EXT CLOCK ALARM
No external clock at DTE.
BPV/CV RCVD
Indicates that a bipolar violation has occurred when set for AMI
line coding. Indicates that a code violation has occurred when set
for HDB3 line coding.
FAS WORD ERROR
Indicates word errors have occurred in the Frame Alignment
Signal.
E-BIT ERROR
Indicates that a Far End Block Error (FEBE) has occurred. This is
