Press Release: GL's Fax, Modem, and
Voice Testing Solutions

Gaithersburg, Maryland, USA - November 16, 2009 - GL Communications Inc. announced today the release of an enhanced portfolio of its Fax, Modem, and Voice Testing solutions. In a statement released to the press Mr. Vijay Kulkarni, CEO of the company said, "GL's s voice, fax, and modem testing portfolio of solutions has been enhanced with an inclusion of T1 E1 Call Capture and Analysis, 2 Wire voice data/recorder, and PacketScan™ applications".

He added, "T1/E1 Call Capture & Analysis application non-intrusively records Voice/Fax/Modem traffic directly from T1/E1 lines and 2-Wire Voice/Data Recorder application used in conjunction with Dual Universal Telephony Adapter (Dual UTA) hardware device captures the voice/fax/modem data manually / automatically from the 2-wire Analog interfaces. And the application PacketScan™ supports capturing and decoding of Fax (T.38 data) calls over VoIP. PacketScan™ fax decodes can be viewed in the form of T.38 call graph and call summary with decoded information for all T.38 messages received on the call. The captured fax calls by PacketScan™ can also be analyzed using the application GLInsight™ by saving the fax calls directly in (*.PCAP) Ethereal file format".

Mr. Kulkarni further added, "To successfully deploy voice, fax, and modem services requires extensive network design, test and traffic engineering. Test equipment can prove valuable in this process, if it can:

  • Generate and receive voice, fax, and modem signals in bulk over wired and wireless networks,
  • Monitor and distinguish voice, fax, and modem signals in real time for traffic engineering and network design purposes,
  • Analyze voice, fax, and modem signals after capture for troubleshooting failed or poorly handled calls".

About GL Communications Inc

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.

GL's TDM Analysis & Emulation line of products includes T1, E1, T3, E3, OC-3, STM-1, 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, etc.), and with capacities up to thousands of channels.

GL's VoIP and IP products generate / analyze thousands of calls / traffic simultaneously with traffic types such as frames, packets, voice files, digits, video, tones, noise, and fax using G.711, G.729, AMR, EVRC, GSM and a range of other codecs. 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 excepted solution across the telecom industry. Voice Quality Testing across multiple networks (T1, E1, T3, E3, OC-3, VoIP, Wireless, and Landline) are all available.

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

GL's Echo Canceller testing solutions provide the broadest range of simulation and analysis, including compliance testing per G.168 and G.160 across TDM, IP, VoIP and Wireless networks. GL's wirelss 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.

GL's 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.

GL's 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 intelligence. Centralized or distributed access, efficient transport and database loading allow compatibility with 3rd party and standards based monitoring systems.
