Not used:
B Side Drop Bus Channel n FIFO Error (Unlatched): A 1 indicates
that the receive FIFO in the desynchronizer for channel n has overflowed
or underflowed for the VT/TU selected. The FIFO is reset automatically.
Line AIS will be sent for two multiframes when enabled.
B Side Drop Bus Channel n VT/TU AIS Detected (Unlatched): A 1
indicates that a AIS state has been detected in the V1/V2 pointer bytes
for the VT/TU selected.
B Side Drop Bus Channel n VT/TU Loss Of Pointer Detected
(Unlatched): A 1 indicates that a loss of pointer (LOP) has been
detected in the V1/V2 pointer bytes for the VT/TU selected.
B Side Drop Bus Channel n VT/TU New Data Flag Indication
Detected (Unlatched): A 1 indicates that a New Data Flag (1001 or
0001/1101/1011/1000) has been detected in the V1 pointer byte for the
VT/TU selected (i.e., bits 1-4 in the V1 byte are the inverse of the normal
0110 pattern or differ in only one bit, with a correct size indicator and a
valid pointer value).
B Side Drop Bus Channel n VT/TU Incorrect Pointer Size Detected
(Unlatched): A 1 indicates that the receive size indicator in the pointer
(Bits 5 and 6 in the V1 pointer byte) is not 11 (DS1) or 10 (e1) for the
VT/TU selected. The detection and recovery time is immediate.
Not used:
B Side Drop Bus Channel n J2 Trail Trace Mismatch (Unlatched)
Alarm: Enabled when control bit BRnJ2S1 and BRnJ2S0 are equal to
01. A 1 indication occurs when the alignment of the 16-byte J2 trace
identifier label (message) has not been established.
B Side Drop Bus Channel n J2 Loss Of Lock (Unlatched) Alarm:
Enabled when control bit BRnJ2S1 and BRnJ2S0 are equal to 01. A 1
indicates that the stable 16-byte message did not match for three mes-
sage time. Recovery occurs when the J2 state machine loses lock and
then acquires lock with a 16-byte stable J2 message that matches the J2
comparison message written by the microprocessor for three consecu-
tive times.
