Force Reframe
A ‘0’ to ‘1’ transition will force the Receive E1 Framer to restart the syn-
chronization process. This bit field is automatically cleared (set to 0)
after frame synchronization is reached.

Loss of CAS Multiframe Alignment Defect Declaration Criteria
Select [1:0]
These two bits permit the user to select the “Loss of CAS Multiframe
Alignment” defect declaration criteria. Loss of CAS Multiframe Align-
ment defect is declared based on the number of consecutive CAS mul-
tiframes with Multiframe Alignment signal received in error as indicated
in the table below.

These bits are active only if CAS Multiframe Alignment is
enabled.

Loss of CRC-4 Multiframe Alignment Defect Declaration Criteria
Select [1:0]
These two bits permit the user to select the “Loss of CRC-4 Multiframe
Alignment” defect declaration criteria for the Channel. The following
table presents the different CRC-4 Multiframe Algorithms in terms of
the number of consecutive erred CRC-4 multiframe alignments that the
E1 Receiver Framer will receive before it declares the “Loss of CRC-4
Multiframe Alignment” defect condition.
N
OTE
:
These bits are only active if CRC Multiframe Alignment is
enabled. If CRC multiframe alignment is not found in 8ms, the
E1 receive framer will restart the synchronization process.
N
OTE
:
TBR-4 standard is enabled by writing to 0xn112, bit 6.
