STS tab for enabling IPPM
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.
IPPM occurs only on STS paths which have IPPM enabled, and TCAs are raised only for PM parameters 
on the selected IPPM paths. The monitored IPPMs are STS CV-P, STS ES-P, STS SES-P, STS UAS-P, 
and STS FC-P. For detailed information about provisioning cards and the procedure for enabling IPPM, 
see 
Note
The far-end IPPM feature is not supported in Software R3.1. However, SONET path PMs can be 
monitored by logging into the far-end node directly.
The ONS 15454 performs IPPM by examining the overhead in the monitored path and by reading all of 
the near-end path PMs in the incoming direction of transmission. The IPPM process allows the path 
signal to pass bidirectionally through the node completely unaltered.
For detailed information about specific PMs, locate the card name in the following sections and review 
the appropriate definition.
