5.2 CRC4 Error Counter
CRC4 Count Register 1 (CRCCR1) is the most significant word and CRCCR2 is the least significant
word of a 10-bit counter that records word errors in the Cyclic Redundancy Check 4 (CRC4). Since the
maximum CRC4 count in a 1-second period is 1000, this counter cannot saturate. The counter is disabled
during loss of sync at either the FAS or CRC4 level; it will continue to count if loss of multiframe sync
occurs at the CAS level.

NOTE:
1.
The upper 6 bits of CRCCR1 at address 02 are the most significant bits of the 12-bit FAS error
counter.
5.3 E-Bit Counter
E-bit Count Register 1 (EBCR1) is the most significant word and EBCR2 is the least significant word of
a 10-bit counter that records Far End Block Errors (FEBE) as reported in the first bit of frames 13 and 15
on E1 lines running with CRC4 multiframe. These count registers will increment once each time the
received E-bit is set to 0. Since the maximum E-bit count in a 1-second period is 1000, this counter
cannot saturate. The counter is disabled during loss of sync at either the FAS or CRC4 level; it will
continue to count if loss of multiframe sync occurs at the CAS level.
