Press Release: GL Releases Enhanced BERT Application

Gaithersburg, Maryland, USA - June 29, 2007 - GL Communications Inc. announced today the release of Enhanced Bit Error Rate Testing Application. Speaking to the media, Mr. Jagadish Vadalia, Senior Manager of Product Development at GL said, "The Enhanced Bit Error Rate Test Application measures the correctness of data received on T1/E1 lines (contiguous and non-contiguous timeslots, sub-channels) according to a repetitive fixed or pseudorandom pattern for a given transmission. It also supports sub-channel selection (fractional BERT within a timeslot) for finer control of testing on individual bits". He added, "The application generates/detects framed, unframed, fractional, and sub channel BER patterns with a variety of standard static and pseudorandom data patterns such as QRSS, All Zeros/ Ones, CSU and NIU Loop-Up/Loop, and user defined patterns".

Mr. Vadalia further added, "The Bit Error Rate Testing can be performed simultaneously in real-time or off-line mode on multiple cards along with a consolidated result view in tabular / graphical formats. The Tx and Rx settings can be independently controlled or set as coupled".

New Features and Enhancements

  • Non-contiguous timeslot and sub-channel selection (Fractional BERT within a timeslot)

  • Testing on multiple cards simultaneously with a consolidated result view

  • Independent settings for Transmit and Receive configurations (timeslot and sub-channel selection)

  • User defined patterns of size up to 32 bits

  • Enhanced error insertion capability

  • Real-time and offline graph view of events

  • Sophisticated logging feature using XML format
