Performance Monitoring for Electrical Cards Chapter 8 Performance Monitoring Table 8-26 Near-End SONET Path PMs for the DS3XM-6 Card Parameter STS CV-P STS ES-P STS FC-P STS SES-P STS UAS-P Definition Near-End STS Path Coding Violations (CV-P) is a count of BIP errors detected at the STS path layer (i.e., using the B3 byte). Up to eight BIP errors can be detected per frame; each error increments the current CV-P second register. Near-End STS Path Errored Seconds (ES-P) is a count of the seconds when at least one STS path BIP error was detected. An AIS-P defect (or a lower-layer, traffic-related, near-end defect) or an LOP-P defect can also cause an STS ES-P. Near-End STS Path Failure Counts (FC-P) is a count of the number of near-end STS path failure events. A failure event begins when an AIS-P failure, an LOP-P failure, a UNEQ-P, or a TIM-P failure is declared. A failure event also begins if the STS PTE that is monitoring the path supports ERDI-P for that path. The failure event ends when these failures are cleared. Near-End STS Path Severely Errored Seconds (SES-P) is a count of the seconds when K (2400) or more STS path BIP errors were detected. An AIS-P defect (or a lower-layer, traffic-related, near-end defect) or an LOP-P defect can also cause an STS SES-P. Near-End STS Path Unavailable Seconds (UAS-P) is a count of the seconds when the STS path was unavailable. An STS path becomes unavailable when ten consecutive seconds occur that qualify as SES-Ps, and it continues to be unavailable until ten consecutive seconds occur that do not qualify as SES-Ps. Table 8-27 Far-End CP-bit Path PMs for the DS3XM-6 Card Parameter DS3 CVCP-P DS3 ESCP-P DS3 SASCP-P DS3 SESCP-P DS3 UASCP-P Definition Code Violation (CVCP-PFE) is a parameter that is counted when the three FEBE bits in a M-frame are not all collectively set to 1. Errored Second (ESCP-PFE) is a count of one-second intervals containing one or more M-frames with the three FEBE bits not all collectively set to 1 or one or more far-end SEF/AIS defects. SEF/AIS Second (SASCP-PFE) is a count of one-second intervals containing one or more far-end SEF/AIS defects. Severely Errored Second (SESCP-PFE) is a count of one-second intervals containing one or more 44 M-frames with the three FEBE bits not all collectively set to 1 or one or more far-end SEF/AIS defects. Unavailable Second (UASCP-PFE) is a count of one-second intervals when the DS3 path becomes unavailable. A DS3 path becomes unavailable when ten consecutive far-end CP-bit SESs occur. The ten CP-bit SESs are included in unavailable time. Once unavailable, the DS3 path becomes available when ten consecutive seconds with no CP-bit SESs occur. The ten seconds with no CP-bit SESs are excluded from unavailable time. 8-32 Cisco ONS 15454 Installation and Operations Guide November 2001
