Overview:

The VQuad™ provides the one box active QoS solution for sending/recording voice over a variety of network interfaces in an automated and synchronized manner. Using the GL VQT, analysis of the recorded voice files can automatically be executed from the VQuad™ in an intrusive manner. The VQT utilizes the ITU algorithms PESQ LQ/LQO/WB, PSQM, and PAMS. In addition to sending/recording voice, the VQuad™ also supports automated call control for establishing calls and verifying the call is up prior to sending/recording voice.

The GL Passive Quality of Service testing allows one to monitor voice anywhere within a network (using the desired VoIP/TDM/Analog Network probe) and gather statistics and quality of service measurements. The various network probes utilize GL hardware and software applications to support T1/E1, Analog, and VoIP networks. All network probes are non-intrusive and require no active testing on either side of the call. Rather, the non-intrusive Passive Monitoring utilizes the metrics from the voice or VoIP RTP and provides statistics, analytical measurements, and in certain cases MOS results.
