Reframe
R/W
0
Force Reframe
A ‘0’ to ‘1’ transition will force the Receive T1 Framer to restart the syn-
chronization process. This bit field is automatically cleared (set to 0)
after frame synchronization is reached.

Framing with CRC

R/W
1
Framing with CRC Checking in ESF
This bit permits the user to include CRC verification as a part of the
“T1/ESF Framing Alignment” process. If the user enables this feature,
then the Receive T1 Framer block will also check and verify that the
incoming T1 data-stream contains correct CRC data, prior to declaring
the “In-Frame” condition.
0 - CRC Verification is NOT included in the “Framing Alignment” pro-
cess.
1 - Receive T1 Framer block will also check for correct CRC values
prior to declaring the “In-Frame” condition.

LOF Tolerance[2:0]
R/W
000
LOF Defect Declaration Tolerance[2:0]:
These bits along with the LOF_RANGE[2:0] bits are used to define the
LOF Defect Declaration criteria. The Receive T1 Framer block will
declare the LOF defect condition anytime it detects
“LOF_Tolerance[2:0]” out of “LOF_Range[2:0] framing bit errors within
the incoming T1 data-stream.
The recommended LOF_TOLR value is 2.
NOTE: A “0” value for LOF_TOLR is internally blocked. A LOF_TOLR
value must be specified.
2-0
LOF_Range[2:0]
R/W
011
LOF Defect Declaration Range[2:0]:
These bits along with the “LOF_Tolerance[2:0] bits are used to define
the “LOF Defect Declaration” criteria. The Receive T1 Framer block will
declare the LOF Defect condition anytime it has received
“LOF_Tolerance[2:0] out of “LOF_Range[2:0] framing bit errors, within
the incoming T1 data-stream.
The recommended LOF_ANG value is 5.
NOTE: A “0” value for LOF_RANG is internally blocked. A LOF_RANG
value must be specified.
