Overview of GL’s range of Echo Canceller Compliance Testing Solutions

•For testing ECs in a TDM environment, both manual, scripted, and automated EC testing solutions are provided for Line Echo Cancellers. Interfaces can be T1 E1 or Analog.
•For manual testing – simple echo generation and measurement tools with graphical output
•For automated testing – the full G.168 compliance test suite can be run at press of a button
•For testing ECs in a VoIP environment, manual and automated solutions are provided for ECs in an ATA
(Analog Telephone Adapter) or a VoIP Gateway
•RTP Toolbox™ and the Dual UTA provide a platform for EC testing on the IP side or 2-Wire side. Gateways with T1 E1 interfaces can also be tested manually or automatically.
•Simulating acoustic echo into a mobile phone or speaker phone
•Simulate acoustic echo for small, medium, or large rooms with "dynamic DSP operators"
•For testing your developmental EC software without any hardware
•Automated EC Testing software can be used to verify compliance of developmental EC software to G.168 standards
•For monitoring and measuring the quality of hundreds and thousands of voice calls over any network
•Voice Band Analyzer with built-in algorithms provides voice quality metrics including: active voice level, line echo, acoustic echo, voice activity, noise levels, and many other voice metrics

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 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.

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.
