Gaithersburg, Maryland, USA - February 17, 2010 - GL Communications Inc. announced today the release of their Automated Network-Wide Voice Quality Monitoring solutions - These offer a complete solution for monitoring voice quality over PSTN, VoIP, TDM, and Wireless telecom networks. Speaking to the press, Mr. Robert Bichefsky, a senior manager at GL said, "Automated Network-Wide Voice Quality Monitoring solution provides remote control and analysis of many VQuad™ Nodes (termination points), either mobile or static, within the testing network. The individual VQuad™ nodes support many interfaces". He added, "Each VQuad™ node possesses the ability to control its far end termination point using TCP/IP for fully synchronous and flexible automation. Also, each VQuad™ node has a very flexible and complex scripting functionality that provides for most all types of network testing".

Mr. Bichefsky, further added, "The output of each VQuad™ node, including recorded voice files, call events, measurement results, error events, timestamps, call ID, and additional information regarding location and test scenario, are all sent to the Central Location via TCP/IP connections. The Central Location includes a database for maintaining the information, a Command Center for flexible control/scheduling of the Network tests, an email function for automated email generation based on errors or failures, and Analysis algorithms for Voice Quality along with delay and echo measurements".

He added, "GL's Automated Network Monitoring solutions are a significant addition to its Network Management Product portfolio considering the growing importance of managing modern day complex network systems".

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.
