PMON (PERFORMANCE MONITORING)
The PMON module uses counters for performance monitoring and
failure/alarms integration. Table-51 shows the performance parameters
that the IDT82V2616 implements. Table-53 lists the failure/alarm signals
sent by alarm messages.

SES-IMA
Link
Count of NE Severely Errored Seconds.
GetLinkPerf command
SES-IMA-FE
Link
Count of FE Severely Errored Seconds.
UAS-IMA
Link
Count of NE UnAvailable Seconds.
UAS-IMA-FE
Link
Count of FE UnAvailable Seconds.
Tx-UUS-IMA
Link
Count of NE Tx Unusable seconds.
Rx-UUS-IMA
Link
Count of NE Rx Unusable seconds.
Tx-UUS-IMA-FE
Link
Count of FE Tx UnUsable Seconds.
Rx-UUS-IMA-FE
Link
Count of FE Rx UnUsable Seconds.
OCD_TC
Link
Count of link out of cell delineation entrances.
HCS_ERR_TC
Link
Count of Cell header sequence error.
IV-IMA
Link
Count of ICP Violations.
Three types of ICP invalid signals will cause the IV-IMA. They are: Errored ICP, invalid ICP and
missing ICP. (See Table-52 for definitions). The IV-IMA is counted only during Non-SES-IMA or
Non-UAS-IMA period.
Rx-Stuff-IMA
Link
Count of received Stuff ICP cells over one link.
Tx-Stuff-IMA
Link
Count of transmitted Stuff ICP cells over one link.
OIF-IMA
Link
Count of Out of IMA Frame anomalies except during SES-IMA or UAS-IMA conditions.
GR-UAS-IMA
Group
Count of Seconds when GTSM is down.
GetGrpPerf command
Table-52 Definitions of Different ICP Cells
ICP Cell Type
Definition
Errored ICP
Cell with a HEC or CRC-10 error at expected ICP frame position and is not a Missing ICP cell.
Invalid ICP
Cell with good HEC and CRC-10 and CID=ICP at expected frame position but with one of the following unexpected errors:
Unexpected IMA label
Unexpected LID
Unexpected IMA ID
Received M
≠ expected M
Unexpected IMA frame sequence number
Unexpected ICP cell offset
Missing ICP
Cell located at ICP cell location with:
No HEC error but without IMA OAM cell header or
No HEC error and with IMA OAM cell header but the CID
≠ ICP.
