Applications and Use
This section provides three common examples of telecommunication network applications. It
details how the
ST2400A 2.4 Gb/s SDH/SONET Test Set
can be used for:
•
Passive Monitoring (Receive-Only)
•
Active Analysis
•
Active Through Mode Analysis

applications such as field service
troubleshooting, engineering analysis, production testing and maintenance will be similar.
Passive Monitoring
The passive monitoring application monitors the 2.4 Gb/s signal. It uses a passive coupler to
connect and disconnect the ST2400A without disrupting live traffic.
This setup is used for non-intrusive network monitoring applications. It is perfect for LEC/IXC
(local exchange carrier / inter-exchange carrier) cross-boundary or other long-term, passive
performance monitoring. It does not allow optical line error injection testing.
This installation splits the STM-16 optical signal through a passive coupler, which can be mounted
in an optical cross-connect bay or other convenient location. Since there is no active regeneration
of the optical line, the system under test must have adequate margin to accommodate the coupler
insertion loss. Measurements are made with the ST2400A, as required.
The CTS850, ST112, or another SDH/SONET tributary test set can be used with the ST2400A to
expand its test capabilities. The ST2400A Receive-Only model is particularly economical for
passive monitoring applications.
