Chapter 15 Performance Monitoring
15.2 Intermediate Path 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):
• 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.
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). Table 15-2
shows ONS 15454 cards that are considered LTE.
