Note: Max value should be the number of cells received in a 15-minute period (or for
Congestion Lost Cells, multiply this by 2). Although 31 or 32 bits are allocated, only
4106.38 cells/sec are received on a T1. In a 15-minute period (900 seconds) only
3695744.68 cell are received. Therefore the max value for all AAL1 sequence errors for
a 15-minute period should be 3695745 (22 bits), and for Congestion Lost cells 7391440
(23 bits).

AAL1 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 underflowed in a 15-minute
period.
ATM / TC LAYER
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. These cells are 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 declaring an alert.
Sets a count of Out of Cell Delineation anomalies that the system can
incur before declaring an alert.
