STM-1 Monitoring Groomer, Hi-Z Non-Intrusive Hi-Impedance
STM-1 Monitoring Solution

Product Overview

Aries Telecom 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.
