Gaithersburg, Maryland (PRWEB) October 04, 2012

GL Communications Inc. a leader in providing PC-based test, analysis and simulation products and consulting services to the worldwide telecommunications industry, conveyed today the availability of its software solution for Echo, Delay and Voice Quality Analysis of Voice Calls in VoIP, TDM, 2-Wire and Mobile Networks.

Speaking to media persons, Mr. Vijay Kulkarni CEO of the company said, GL's Echo Measurement Utility (EMU) software is an offline adjunct analysis application (under control of VQuad) that compares the source and received files to determine echoes and delay of echoes. EMU software assesses sidetone, line, and acoustic echo and the corresponding delays.

He added, GLs EMU Software measures Echo Path Delay (EPD) and Echo Return Loss (ERL) of voice calls. Echo can be as simple as sidetone, or more complex such as line, and acoustic echo. The EMU when combined with GL's VQuad, Dual UTA, T1/E1 Analyzers, RTP Toolbox, WEBViewer. or Voiceband Analyzer, additional voice quality metrics such as round trip delay (RTD), voice quality, and noise can also be measured.

Mr. Kulkarni further added, To provide a comprehensive assessment of voice quality irrespective of network type, GL has combined various tools together into one platform consisting of VQuad, Dual UTA, USB T1 E1, and WEBViewer. This platform provides the ability to make VoIP, TDM, and Mobile calls from any fixed or mobile location. All interface flexibility is provided (2Wire, 4Wire, VoIP, TDM, and Mobile) within the Dual UTA and USB T1 E1 Analyzers. In addition, VQuad provides algorithms for signaling, voice transmission, and voice quality assessment. WEBViewer provides the central point where voice metrics are stored and displayed through a WEB interface.
