*BPV (Bi-Polar Violation) = Occurrence of pulses of same polarity as the previous pulse except
as part of the B8ZS substitution code.
*ExZ (Excessive Zero) = Occurrence of any zero string greater than "N" contiguous zeros,
where "N" = 7 for B8ZS or 15 for AMI (Alternate Mark Inversion).

AAL 1 LAYER
Indicates a count of AIS cells inserted into the data stream for stuffing
purposes in a 15-minute interval.
Indicates a count of cells discarded in a 15-minute interval.
A count of "Out of Sequence" transitions in a 15-minute interval.
A count of cells lost in a 15-minute interval.
Indicates a count of buffers that have overflowed in a 15-minute period.
Indicates a count of buffers that have under flowed in a 15-minute period.
ATM / TC
Suspect defines counts that are suspected to have errors but may have been
reset to zero by a user during the reporting period.
Suppressed intervals flag indicates that there was no data to report for an
interval (all counts are zero). This saves the user from having to look at a
bunch of zeros and also reduces the size of the PM data files.
Sets a count of errors in the ATM header that the system can incur before
notifying the system administrator.
A count of Operation, Administration, and Maintenance cells received in a
15-minute period, used for testing purposes such as loopback request
codes.
A total count of all of the cells that have been received on an interface.
This is for user information and not configurable.
A total count of all of the cells that have been transmitted out from an
interface. This is for user information and is not configurable.
Sets a count of Header Error Checksum violations that the system can
incur before notifying the system administrator.
Sets a count of Out of Cell Delineation anomalies that the system can incur
before notifying the system administrator.
