Reframe

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 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 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.

A “0” value for LOF_TOLR is internally blocked. A LOF_TOLR
value must be specified.

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.
N
OTE
:
A “0” value for LOF_RANG is internally blocked. A LOF_RANG
value must be specified.
