This section describes the performance monitoring parameters that are applicable to SONET EC-1 signals.
The following table lists the SONET EC-1 line performance parameters that Alcatel-Lucent 1665 DMX monitors, including the default and ranges for the 15-minute and 1-day (24-hour) registers.

When an individual performance monitoring parameter threshold is provisioned as zero (0), TCA reporting for the affected parameter is disabled.
Alcatel-Lucent 1665 DMX monitors the following near end SONET line parameters on incoming (from the local cross-connect) EC-1 signals. The parameters are measured at the input of the 12DS3/EC1 circuit pack on the EC-1 line side (also referred to as facility, customer terminal, or STSX-1 side).
The Near-End Line Coding Violation (CVL) parameter for each SONET Line is monitored. The Near-End CVL parameter increments once for every occurrence of a BIP error detected at the Line layer (i.e. using the B2 byte in the incoming SONET signal). Up to 8*N BIP errors can be detected per STS-N frame.
The Near-End Line Errored Seconds (ESL) parameter for each SONET Line is monitored. The Near-End CVL parameter increments once for every second that contains at least one BIP error detected at the Line layer (at any point during the second), or an AIS-L defect was present.
The Near-End Line Severely Errored Seconds (SESL) parameter for each SONET Line is monitored. The Near-End SESL parameter increments once for every second that contains at least K BIP errors detected at the Line layer (at any point during the second), or an AIS-L defect was present. The value of K is hard-coded, see table 7 for a list of the values
The Near-End Line Unavailable Seconds (UASL) parameter for each SONET Line is monitored. The Near-End UASL parameter increments once for every second that the Line was considered unavailable (at any point during the second). A Line becomes unavailable at the onset of 10 consecutive seconds that qualify as Near-End SESLs, and continues to be unavailable until the onset of 10 consecutive seconds that do not qualify as Near-End SESLs.
The Far-End Line Failure Counts (FC-L) parameter for each SONET line is monitored. The Far-End FC-L parameter increments once for the beginning of each RFI-L event (RFI-L detected and cleared). A failure that begins in one period and ends in another period, is counted in the period in which it begins.
This is a calculation of the absolute value of the PJC parameters listed under the headings below. PJCDIFF-P is used to calculate the difference between calculate the difference between the PPJC-PGEN, NPJC-PGEN and between PPJC-PDET and NPJC-PDET. Alcatel-Lucent 1665 DMX monitors the first cross-connected STS. From this STS, the calculation is to (A) calculate the difference between the PPJC-PGEN, NPJC-PGEN. (B) Calculate the difference of the PPJC-PDET, NPJC-PDET. The resulting PJC is the absolute value of the difference between A and B.
This parameter summarizes all Negative Pointer Justifications detected by the system. Alcatel-Lucent 1665 DMX monitors negative line Pointer Justifications on an STS-1 within the OC-n line in 1 second intervals. (Users may select which STS-1 to monitor by provisioning the PJC Monitoring point parameter using the Performance → Provision PM command.) The count increments for each incoming negative STS pointer justification.
This parameter summarizes all Positive Pointer Justifications detected by the system. Alcatel-Lucent 1665 DMX monitors positive line Pointer Justifications on an STS-1 within the OC-n line in 1 second intervals. (Users may select which STS-1 to monitor by provisioning the PJC Monitoring point parameter using the Performance → Provision PM command.) The count increments for each incoming positive STS pointer justification.
This parameter summarizes all Negative Pointer Justifications generated by the system. Alcatel-Lucent 1665 DMX monitors negative line Pointer Justifications on an STS-1 within the OC-n line in 1 second intervals. (Users may select which STS-1 to monitor by provisioning the PJC Monitoring point parameter using the Performance → Provision PM command.) The count increments for each outgoing negative STS pointer justification.
