Press Release: GL Announces Enhanced T1 E1 Products and Software

Gaithersburg, Maryland, USA - May 18, 2010 - GL Communications Inc. announced today the release of T1 E1 Analyzer Software Version 5.32 with new applications and enhancements. In a statement issued to the press, Mr. Vijay Kulkarni, CEO of the company said, "Our T1 E1 Analysis suite of products provides comprehensive analysis and emulation capabilities for voiceband analysis and signaling protocol analysis. The new applications introduced into the T1 E1 version 5.32 are: Protocol Identifier, SS1 Analysis & Emulation (Includes SS1 Dialer and SS1 Analyzer), and Multi-Channel Audio Monitoring Bridge".

He added, "Protocol Identifier classifies all HDLC based, ATM, and TRAU protocols. And the application SS1 Analyzer detects and analyzes tone sequences that makes up SS1 dial digits and SS1 dialer allows users to setup and dial tone sequences that make up SS1 dial digits. The applications' interface includes options to set up and place a call, and control mask & space frequencies and duration, and other parameters related to the digit dialer.

The Multi-Channel Audio Monitoring application helps listening to T1 E1 timeslots directly on your PC speaker or for inserting Microphone or Line-In signals into T1 E1 timeslots. It provides a bridge between T1 E1 timeslots and single or multichannel sound card(s). The application can also interwork with other "sound card aware" applications like Goldwave, Cool Edit, Adobe Audition, Audacity, Matlab, LabView and many others. Audio can be transmitted or received using G.726 (40 kbps, 32 kbps, 24 kbps, or 16 kbps) codec format for direct insertion into T1 E1 timeslots, along with the usual u-law or A-law formats".

Mr. Kulkarni further added, "In addition to the above new applications, a host of significant enhancements were introduced to the following products: Multiple Call Capture, MAPS (Message Automation & Protocol Simulation), WCS ML-PPP Emulator, Protocol Analyzer and Windows Client server".

He emphasized , "The addition of the new applications and the enhancements to the existing applications of the T1 E1 Analyzer product suite enhances significantly the user experience and adds value to the T1 E1 testing needs of the customers".

A brief summary of the enhancements in the T1 E1 Analyzer - 5.32 Release are:

  • Multiple Call Capture
    • Added the option of prepending the "probe capture name" to the filename, as part of profile loading/saving
    • Added direction indicator, 'E' or 'W', to SS7 capture filenames

  • MAPS (Message Automation and Protocol Simulation)
    • Encoding support for CSN based classes has been added
    • ISDN - 5ESS variant has been added

    • Optional NCP negotiation

  • Protocol Analyzers
    • HDLC and PPP Protocol Analyzers support decoding of Cisco HDLC standard
    • INI Decode Option changed in ATM, UMTS, SaBit HDLC, and MLPPP Protocol Analyzers

  • Windows Client Server application

Founded in 1986, GL Communications Inc. is a leading supplier of test, monitoring, and analysis equipment for TDM, Wireless, IP and VoIP networks. Unlike conventional test equipment, GL's test platforms provide visualization, capture, storage, and convenient features like portability, remotability, and scripting.

GLís TDM Analysis & Emulation line of products includes T1, E1, T3, E3, OC-3, OC-12, STM-1, STM-4, analog four-wire, and analog two-wire interface cards, external portable pods, and complete system solutions. Capabilities include voiceband traffic analysis and emulation across all traffic types (voice, digits, tones, fax, modem), all protocols (ISDN, SS7, GR-303, Frame Relay, HDLC, V5.X, ATM, GSM, GPRS, LTE, etc.), and with capacities up to thousands of channels. Our newest products provide astonishing capacity and capture capability up to and including gigabit speeds.

GLís VoIP and IP products generate / analyze thousands of calls and traffic simultaneously with traffic types such as frames, packets, voice files, digits, video, tones, noise, and fax. Almost all codecs are supported including G.711, G.729, AMR, EVRC-A,B,C, GSM, iSAC, and many more. Additional features include visual analysis, real-time listening, and recording. The product line also includes Ethernet / IP Testing capability that simulates and checks frame transport and throughput parameters of Ethernet and IP networks, including delay, errors and other impairments.

GL's Voice Quality Testing (VQT) product line complements all of GL's products. Using ITU-standard algorithms (PAMS, PSQM, and PESQ), GL's VQT provides a widely accepted solution for assessing voice quality in the telecom industry. Voice Quality Testing across multiple networks (T1, E1, T3, E3, OC-3, OC-12, VoIP, Wireless, and Landline) are all available.

GLís Wireless Products perform protocol analysis and voice quality assessment on GSM, CDMA, UMTS, and LTE networks. Connections can be made to any wireless phone with automated call control, GPS mapping and real-time signal measurements.

GLís Echo Canceller testing solutions provide the broadest range of simulation and analysis, including line and acoustic echo. GLís compliance testing per G.168. G.167 and P.340 across TDM, IP, VoIP and Wireless networks is widely accepted in the industry.

GLís wireless VQT solutions help assessing impairments to voice quality such as poor mobile phone quality, voice compression and decompression algorithms, delay, loss and gain in speech levels, noise, acoustic and landline echo, and other distortions are easily assessed and accurately measured.

GLís Handheld data testers can test a wide variety of communications facilities and equipment including T1, fractional T1, E1, fractional E1, T3 and E3 modems, multiplexers, CSU, DSUs, T1 CSUs, DTUs, NTUs and TIUs and more. The testers provide convenience, economy, and portability for almost any interface, including RS232, RS-422, RS-530, X.21, T1, E1, T3, E3, and many others.

GLís Network Surveillance and Monitoring products include Probes for TDM, IP, VoIP, ATM, and Wireless networks. An open standards based approach provides a scalable, feature rich, real-time access to network characteristics. Centralized or distributed access, efficient transport and database loading allow compatibility with 3rd party and standards based monitoring systems.
