Performance Monitoring; Fibre Channel Extended Reach - Nortel NTRN10AN Planning Manual

Performance Monitoring

Performance monitoring (PM) refers to the in-service, non-intrusive
monitoring of transmission quality. The 2xGigE/FC-P2P circuit pack will
support the PM counts shown in
be monitored and binned for Ethernet and WAN signals.
Binning is supported for counts:
•
•
•
Various counters are also binned:

Fibre Channel Extended Reach

Fibre Channel extended reach avoids throughput degradation for distances up
to approximately 980 kilometers (kms) at full rate or about 18000 kilometers
(kms) at sub-rate (STS1), see
means the ability to use 100% of the available WAN bandwidth.
