7.8 DS3/E3 Performance Error Counters
There are six internal error counters and six corresponding error count registers in the DS3/E3 framer. All of the
error counters and count registers are 16 bits in length. The framer can be configured to update the count registers
with the latest counter values automatically once a second or manually through either the MECU bit in the MC1
register or the RECU input pin. When the count registers are updated through any of these methods, the internal
error counters are reset to 0. All the error counters saturate when full and do not roll over. When any of the error
counters are saturated, the COVF bit is set in the MSR register.

Bits 0 to 15: Bipolar Violation Count (BPV[15:0]). This count register contains the value of the internal BPV/CV
error counter latched during the last error counter update. In DS3 mode, the internal counter counts bipolar
violations (BPV). In the E3 mode, the counter can be configured through the E3CVE bit in the T3E3CR2 register to
count BPVs or code violations (CV). A BPV is defined as consecutive pulses (or marks) of the same polarity that
are not part of a B3ZS/HDB3 codeword. A CV is defined in ITU O.162 as two consecutive BPVs of the same
polarity. When the line interface is in binary mode (BIN = 1 in the MC1 register), the internal counter increments for
each RCLK clock cycle that the RLCV pin is active. The RLCV pin is normally active high but can be inverted using
the RNEGI bit in the MC5 register. The BPV counter ignores the RLCV pin when the device is in diagnostic
loopback (DLB = 1 in register MC2).

Bits 0 to 15: Excessive Zero Count (EXZ[15:0]). This count register contains the value of the internal EXZ error
counter latched during the last error counter update. The internal counter counts excessive zero occurrences
(EXZ). An EXZ occurrence is defined as three or more consecutive 0s in DS3 mode and four or more consecutive
0s in E3 mode. As an example, a string of eight consecutive 0s is a single EXZ occurrence and would only
increment this counter once.
