GL Communications' PC Based OC-3/STM-1 solution allows the user to turn his PC or Laptop into a powerful OC-3 or STM-1 analyser.  These high performance analysis cards can add and drop T1, E1, T3 or STS-1/STM-0 signals to or from an OC-3/STM-1 signal.  Able to monitor and generate Sonet and SDH Alarms and Errors, as well as internally generate BERT patterns in all frame modes, GL's OC3/STM1 card is a valuable tool for developers and integrators.

Capabilities

• OC-3/STM-1, STS-1/STM-0, T3, T1, E1 Interfaces.
• Generate and Monitor SDH/Sonet Alarms and Errors.
• Add/Drop selected PDH Signals (T1, E1, T3, STS-1/STM-0).
• Internally Generated BERT patterns in all modes.

Tests Performed

Capable of utilising internal, external and recovered clock signals, the GL OC-3/STM-1 PC based solution provides real time monitoring control of all the major Sonet and SDH overheads, alarms and errors.  GL's STM-1 Ultra Card is capable of selecting individual T1/E1's to be added/dropped or transmitting on user defined E1 or T1 trunks whilst all the remaining E1's or T1's within the STM-1/OC-3 are either looped or broadcast.

Summary

GL's Ultra OC-3/STM-1 Card (PCI) plugs into a PC expansion slot for analysing, testing, simulating, and monitoring OC-3/STM-1 and STS-1/STM-0 signals.  SONET/SDH Alarm generation, Error injection and detection capability, overhead monitoring features and its many other features make GL's Ultra OC-3/STM-1 Analyser a complete SONET and SDH testing solution.
