Performance Monitoring

P
ERFORMANCE
In addition to the standard features of the HRU-402, its functionality has been
enhanced to produce unique Performance Monitoring (PM) and testing
capabilities.
Network surveillance is a key maintenance strategy. Real-time monitoring of
performance through sectionalized analysis allows maintenance personnel to
quickly locate a service degradation or failure. This also makes it easier to
determine if the customer or network operator must bear responsibility for
service and repair.
The Performance Monitoring screens analyze the T1 transmission by tracking
the four transmission legs shown in

PPLICATIONS
When installed individually on one end of a T1 circuit, the remote unit
provides the following special network benefits:
•
Real-time performance monitoring of DS1 signals in both directions of
transmission
•
Non-intrusive access to real-time performance monitoring data
(CPE-provided ESF signal)
