Press Release: GL Announces Wireless Backhaul Testing Solutions

Gaithersburg, Maryland, USA - March 12, 2009 - GL Communications Inc., announced today the release of Wireless Backhaul Testing Solutions. In a statement release to the press, Mr. Jagadish Vadalia Senior Manager at GL said, "With the rapid rise in mobile communications, and as data and video penetrate the mobile market; wireless backhaul is gaining popularity due in large part to its cost efficiencies. IP and Ethernet backhaul over fiber, microwave, and even TDM (T1 E1 T3 E3 OC-3 and OC-12) is gaining momentum. Operators have chosen alternate backhaul solutions such as leased T1 E1, Ethernet, IP, Satellite, Microwave, and Fiber to minimize expenses". He added, "When traditional T1 E1 circuits from telco are not available, or too expensive, operators may resort to satellite or microwave transmission. Ethernet backhaul may also be considered. Each technology has differing delays, error performance, and reliability characteristics. A network operator must be equipped with proper tools to monitor, troubleshoot, and assess various types of backhaul options:

Assessing performance of legacy transmission (T1 E1) or Ethernet backhaul requires test tools that can measure clock accuracy, clock jitter, bit error rate, packet jitter, packet loss, round trip delay and throughput. All of these functions in a single test set is preferable
If the same tool can also be used for installation, maintenance, and performance monitoring, so much the better.

Mr. Vadalia further added, "GL provides various testing solutions to monitor and test backhaul networks. Our test gear helps test backhaul no matter what the media; are portable, hand-held, or PC based, and is used successfully by customers world-wide to monitor and troubleshoot deployed networks".

Main Features

Test T1 E1 T3 E3 cellular backhaul (delay, throughput, error free transmission)
Test cellular IP backhaul, carrier Ethernet backhaul, etc
Test point-to-point and multipoint circuits
Simulate backhaul systems in the convenience of your Lab

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 products generate / analyze thousands of calls simultaneously with traffic types such as 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 a Software Ethernet Testing capability that checks frame transport and throughput parameters of Ethernet and IP networks.

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, Landline, etc.) 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, RS422 / RS530, 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.
