STM-1
Monitoring Groomer
Non-Intrusive
STM-1 Monitoring Solution
Product Overview
Orion Telecom Networks
Inc. offers the VCL-STM-1 Monitoring
Groomer is a cost-effective monitoring and grooming equipment which
may be used to "non-intrusively" monitor "bi-directional" STM-1
links through a 80:20 optical splitter patch panel and allow the
user to select 64Kbps time-slots and groom them to E1 output ports,
which may be then connected to E1 probes, E1 signaling analyzers and
billing servers etc.
The equipment provides as many as 32
E1 output ports to which the selected / groomed 64Kbps time-slots
may be output.
The figure shown below, illustrates a
typical "non-intrusive", bi-directional monitoring application of an
STM-1 link in both east and west directions and the groomed
time-slots are output to E1 interfaces.

Note: The Optical signal is "tapped" through an
optical patch panel using a 80:20
optical signal
splitter.
