Disclosing to the news media, Mr. Vijay Kulkarni, CEO of the company, said, "GL Communications has a broad range of testing solutions for echo cancellers (EC) in any network environment - TDM, VoIP, and Wireless. Echo can be heard on 2-wire POTS lines, mobile phones, VoIP calls, and speaker phones. The diagram below provides a glimpse of echo possibilities and locations".
He added, "Our platforms for testing EC software can be Universal T1 E1 Cards, portable USB Based T1 E1 Units, Ethernet Interfaces, or no hardware whatsoever".
- 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, voice activity, noise levels, and many other voice metrics

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.
GL's 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.
GL's Echo Canceller testing solutions provide the broadest range of simulation and analysis, including line and acoustic echo. GL's compliance testing per G.168. G.167 and P.340 across TDM, IP, VoIP and Wireless networks is widely accepted in the industry.
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 characteristics. Centralized or distributed access, efficient transport and database loading allow compatibility with 3rd party and standards based monitoring systems.
