T3 Alarm Criteria Table 5.3A
Alarm/
Condition
Definition
Set Criteria
Clear Criteria
AIS
Alarm Indication Signal
Properly framed 1010...
pattern which is aligned
with the 1 just after each
overhead bit and all C Bits
are set to zero
In each 84 bit information
field, the properly aligned
10... pattern is detected with
less than 4 bit errors (out of
84 possible) for 1024
consecutive information bit
fields (1.95ms) and all C
Bits are majority decoded to
be zero during this time
In each 84 bit information
field, the properly aligned
10... pattern is detected
with 4 or more bit errors
(out of 84 possible) for
1024 consecutive
information bit fields
(1.95ms)
LOS
Loss Of Signal
192 consecutive zeros
No EXZ events over a 192
bit window that starts with
the first one received
LOF
Loss Of Frame
Too many F Bits or M Bits
in error
3 or more F bits in error out
of 16 consecutive or 2 or
more M bits in error out of
4 consecutive
Synchronization occurs
RAI
(note: RAI
can also be
indicated via
FEAC codes
in the C-Bit
Parity Mode)
Remote Alarm Indication
(this is also referred to as
SEF/AIS in Bellcore GR-
820)
X1 = X2 = 0 (active)
X1 = X2 = 1 (inactive)
X1 and X2 = 0 for 4
consecutive M frames
(426us)
X1 and X2 = 1 for 4
consecutive M frames
(426us)
Idle Signal
Properly framed 1100...
pattern which is aligned
with the 11 just after each
overhead bit and the C Bits
in Subframe 3 are zero
In each 84 bit information
field, the properly aligned
1100... pattern is detected
with less than 4 bit errors
(out of 84 possible) for
1024 consecutive
information bit fields
(1.95 ms) and the C Bits in
Subframe 3 are majority
decoded to be zero during
this time
In each 84 bit information
field, the properly aligned
1100... pattern is detected
with 4 or more bit errors
(out of 84 possible) for
1024 consecutive
information bit fields
(1.95 ms)
