GAITHERSBURG, Md., Aug. 31, 2021 (GLOBE NEWSWIRE) -- GL Communications Inc., announced today the release of its latest T1 E1 Emulation/Analyzer products and software covering new applications, enhancements and added features.

Speaking to the press, Mr. Vijay Kulkarni, CEO said, “The T1 E1 Analysis Suite of products provides comprehensive analysis and emulation capabilities for voiceband analysis and signaling protocol analysis. The new application is added to support unframed mode in “Frame Relay Emulator” where the user can include Timeslot 0 for transmission/reception and enhanced T1 E1 BERT commands to give error insertion rate and bit inversion capability. Now, Packet Data Analysis has been introduced for offline protocol analyzers – CAS, SS7, ISDN, and GSM. Supported protocols include AIN, CAMEL, MAP, ANSI TCAP, and CNAM over the ATM layer in our MAPS™ application.”


He further added, “There are some significant enhancements in the T1 E1 Protocol Analyzers, it permits the user to create aggregate column priority groups, and aggregate column items user interface for reversing order src->dst or dst->src and rearrange it in any order using GUI. We also, added protocol decode errors and data link errors for searching and filtering criteria.”

Latest enhancements on the following applications include:


  • MAPS™ Command Line Interface (CLI):
    • Updated CLI with Python client and parser files for 32/64-bit versions and Python versions 2 and 3
    • Support for decoding UK caller ID
  • MFR-IP-PacketCheck™:
    • Bandwidth Configuration and Transmission Rate Control is now applicable to per stream instead of per virtual channel
    • Selection of Packet Mode for each stream is provided based on the default values that are selected and loaded to the respective configuration fields. Customization of those configuration values is also provided
    • Supported Packet Mode selection options are FR-Route, FR-Bridge, FR-Q.933, PPP-IPV4, PPP-LCP, and Custom
    • Transmit and Receive option now supports for Non-MFR Frames
    • Default flags between frames have been changed from 100 to 1
  • Datacom Analyzer:
    • Included WCS scripts for Datacom interface and enhanced BERT WCS script for Datacom, T1, and E1 analyzer
  • MAPS™ Analog Phone/Line Simulator (APS):
    • The Voiceband Measurement (VBM) synchronization mechanism uses single-frequency tone instead of DTMF
    • Debug option has been included to show on/off time for detected call progress tones and to record call setup
