Bipolar
Violation
Integer tally of
violation count
since last reset.
Two successive pulses of the same polarity
have been received and these pulses are not
part of zero substitution. On an AMI-encoded
line, this represents a line error. On a B8ZS
line, this may represent the substitution for a
string of 8 zeroes.
Receive Slip Tally since last
reset.
A receive slip (positive or negative) has
occurred. Slips indicate a clocking mismatch
(or lack of synchronization) between T1/E1
devices. When slips occur, data may be lost or
repeated.
