DEFINITION
SET CRITERIA
CLEAR CRITERIA
Four or fewer zeros in
two consecutive 1536-
bit frames
192 consecutive zeros
Five or more zeros in two
consecutive 1536-bit frames
LOS
Loss Of Signal
(See Note)
No EXZ events over a 192-
bit window that starts with
the first one received
Three consecutive good
FAS
Bit 11 = 0 for 4 consecutive
frames (6144 bits / 179μs)
LOF
Loss Of Frame
Too many FAS errors
Remote Alarm Indication
Inactive: Bit 11 of the frame = 0
Active: Bit 11 of the frame = 1
Four consecutive bad
FAS
Bit 11 = 1 for 4
consecutive frames
(6144 bits / 179μs)

Note:
Bits that are underlined are read-only; all other bits are read-write.
The status bits in the T3E3INFO cannot cause a hardware interrupt to occur.
Bit 0/Change Of Frame Alignment Detected (COFA).
This latched read-only event-status bit will be
set to a one when the T3/E3 framer has experienced a change of frame alignment (COFA). A COFA
occurs when the device achieves synchronization in a different alignment than it had previously. If the
device has never acquired synchronization before, then this status bit is meaningless. This bit will be
cleared when read and will not be set again until the framer has lost synchronization and reacquired
synchronization in a different alignment.
Bit 1/Zero Suppression Code Word Detected (ZSCD).
This latched read-only event-status bit will be
set to a one when the T3/E3 framer has detected a B3ZS/HDB3 code word. This bit will be cleared when
read and will not be set again until the framer has detected another B3ZS/HDB3 code word.
