Karnataka, GL Communications Inc., announced today availability of its Wireless Backhaul Testing Solutions to Wireless and VoIP user community. Speaking to press, Mr. Vijay Kulkarni CEO of the company said, As data and video penetrate the mobile market, there is a rapid rise in the volume of traffic carried by wireless networks. An efficient wireless backhaul architecture is paramount if costs are to be contained. IP and Ethernet backhaul over fiber, microwave, and even TDM (T1 E1 T3 E3 OC3 and OC12) is gaining momentum as carriers look 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:
1. 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
*2. If the same tool can also be used for installation, maintenance, and performance monitoring, so much the better.
Mr. Kulkarni 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, GLs test platforms provide visualization, capture, storage, and convenient features like portability, remotability, and scripting.
GLs 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.
GLs 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.
GLs Voice Quality Testing (VQT) product line complements all of GLs products. Using ITU-standard algorithms (PAMS, PSQM, and PESQ), GLs 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.
GLs 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.
GLs 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. GLs 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.
GLs 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.
GLs 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.
