Intermediate-Path Performance Monitoring Reference

8.2 Intermediate-Path Performance Monitoring Reference

Intermediate-path-performance monitoring (IPPM) allows transparent monitoring of a constituent
channel of an incoming transmission signal by a node that does not terminate that channel. In addition
to the path-terminating equipment (PTE) on the XTC, such as DS1s and DS3s, an ONS 15327 can
terminate optical
the Provisioning > STS tabs for an OC-3 card.

Software R3.0 and higher allows LTE cards to monitor near-end PM data on individual STS payloads by
enabling IPPM. After enabling IPPM provisioning on the line card, service providers can monitor large
amounts of STS traffic through intermediate nodes, thus making troubleshooting and maintenance
activities more efficient.
