5.6 T3/E3 Performance Error Counters
There are six error counters in the DS3112. All of the errors counters are 16 bits in length. The host has
three options as to how these errors counters are updated. The device can be configured to automatically
update the counters once a second or manually via either an internal software bit (MECU) or an external
signal (FRMECU). See Section 4.2 for details. All the error counters saturate when full and will not
rollover.

Note: Bits that are underlined are read-only; all other bits are read-write.
Bits 0 to 15: 16-Bit BiPolar Violation Counter (BPV0 to BPV15). These bits report the number of BiPolar
Violations (BPV). In the E3 Mode, this counter can also be configured via the E3CVE bit in the T3E3 Control
Register (Section 5.2) to count 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.161 as consecutive BPVs of
the same polarity.

Bits 0 to 15: 16-Bit EXcessive Zero Counter (EXZ0 to EXZ15). These bits report the number of EXcessive Zero
occurrences (EXZ). An EXZ occurrence is defined as three or more consecutive zeros in the T3 mode and four or
more consecutive zeros in the E3 mode. As an example, a string of eight consecutive zeros would only increment
this counter once.
