Press Release: GL Announces Automated
Network-Wide Voice Quality Monitoring

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.

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.
