Chapter 15 Performance Monitoring
Due to memory limitations and the number of TCAs generated by different platforms, you can manually
add/modify the following two properties to the platform property file (CTC.INI for Windows and .ctcrc
for UNIX):
•
•
If the number of the incoming TCA is greater than the hiwater mark, the node will keep the latest lowater
mark and discard older ones.

15.2 Intermediate Path Performance Monitoring

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. Many large
networks only use line terminating equipment (LTE), not path terminating equipment (PTE).
shows ONS 15454 cards that are considered LTE.

1. An OC-48 IR card used in a bidirectional line switched ring (BLSR) does not support IPPM during a protection switch.
ONS 15454 Software R3.0 and higher allows LTE cards to monitor near-end PM data on individual
synchronous transport signal (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 that have IPPM enabled, and TCAs are raised only for PM parameters
on the IPPM enabled paths. The monitored IPPM parameters are STS CV-P, STS ES-P, STS SES-P,
STS UAS-P, and STS FC-P.

ctc.15xxx.node.tr.lowater=yyy where xxx is the platform and yyy is the number of the lowater
mark. The default lowater mark is 25.
ctc.15xxx.node.tr.hiwater=yyy where xxx is the platform and yyy is the number of the hiwater
mark. The default hiwater mark is 50.
