Performance Monitoring
...................................................................................................................................................................................................................................
Overview
•
Performance monitoring is in accordance with ITU-T G.826 and G.784
•
The following four parameters are available to estimate the error performance of a
path:
–
SES: number of Severely Errored Seconds in the received signal
–
ES: number of Errored Seconds in the received signal
–
BBE: number of Background Block Errors in the received signal
–
UAS: number of UnAvailable Seconds in the received signal
•
For termination points, Near-End Performance Monitoring can be done on the
incoming MS16, MS4, MS1, VC-4, VC-3, and VC-12 signals. Non-intrusive
monitoring is only possible for AU-4 signals.
•
Bi-directional and unidirectional performance monitoring
•
Performance monitoring data is stored in one current and sixteen recent 15 minutes
registers, and one current and one recent 24 hours registers. Detailed information
about Performance Monitoring are provided in the following sections.
•
Threshold reports are generated when user-settable performance parameters are
exceeded during 15 minutes and 24 hours periods
•
Ethernet performance monitoring information can be derived from the General
Purpose Ethernet Port Monitor, Ethernet Service Monitor, Ethernet Congestion
Monitor, Ethernet High Priority Traffic Monitor, Ethernet Low Priority Traffic
Monitor, and Ethernet Frame Delay Monitor.. This information is available in 15
minutes or 24 hours registers. For more information about Ethernet Performance
Monitoring features, see
“Advanced TransLAN® Features” (p. 2-57)
Capacity for 200 Monitoring Points per Tributary Slot
In addition to the capacity limit for the number of simultaneously active PM points at
the system level (600 in Release 4.0), there is a limit of 200 performance monitoring
points for each slot in the system. For more information, refer the Metropolis

AMU
User Operations Guide.
