BPVCR1.7
MSB of the bipolar violation count.
BV0
BPVCR2.0
LSB of the bipolar violation count.
Bipolar Violation Count Register 1 (BPVCR1) is the most significant word and BPVCR2 is the least
significant word of a 16-bit counter that records bipolar violations (BPVs). If the HDB3 mode is set for
the receive side via CCR.2, then HDB3 code words are not counted. This counter increments at all times
and is not disabled by loss of sync conditions. The counter saturates at 65,535 and will not rollover. The
bit error rate on a E1 line would have to be greater than 10**-2 before the BPVCR would saturate.

CRCCR2.0
LSB of the CRC4 error count.
CRC4 Count Register 1 (CRCCR1) is the most significant word and CRCCR2 is the least significant
word of a 16-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 sync occurs at the
CAS level.
