In Frame State:
This READ-ONLY bit indicates whether the Receive E1 Framer block is
currently declaring the “In-Frame” condition with the incoming E1 data-
stream.
0 - Indicates that the Receive E1 Framer block is currently declaring the
LOF (Loss of Frame) Defect condition.
1 - Indicates that the Receive E1 Framer block is currently declaring itself
to be in the “In-Frame” condition.

0
TBR4 Standard
Setting this bit will force the XRT86VL32 to be compliant with the TBR-4
standard for “Loss of CRC-4 Multiframe Alignment Criteria”.
0 - Backward compatible with XRT86L38 for Loss of CRC-4 Multiframe
Criteria. When CRCC[1:0] (from register 0xn10B) is set to’11’, Loss of
CRC-4 Multiframe Alignment will declare if 915 or more CRC-4 errors
have been detected in 1 second.
1 - “TBR-4 Compliant” Loss of CRC-4 Multiframe Alignment Criteria -
When CRCC[1:0] (from register 0xn10B) is set to’11’, Loss of CRC-4 Mul-
tiframe Alignment will declare if 4 consecutive CRC-4 Multiframe Align-
ment have been received in error OR if 915 or more CRC-4 errors have
been detected in 1 second.

CAS Multi-Frame Yellow Alarm
This READ ONLY bit field indicates the value of the most recently
received CAS Multiframe Yellow Alarm Bit (bit 6 within timeslot 16 of
frame 0 of the signaling multiframe).
0 = Indicates that the E1 receive framer block is NOT receiving the CAS
Multiframe Yellow Alarm.
1 = Indicates that the E1 receive framer block is currently receiving the
CAS Multiframe Yellow Alarm.
