“GL’s VQuad™ 24-port HD FXO system is an all-in-one 2U rack supporting full call control and FXO special services on 24 FXO ports along with both Wide Band (WB) and Narrow Band (NB) Audio.  VQuad™ HD FXO platform offers an automated, scripted, remote-access, multi-user, multi-protocol, and high capacity FXO test solution”, said Robert Bichefsky Director of Engineering at GL Communications.

“In addition, the VQuad™ solution supports DTMF digits, single and dual-frequency tones, energy detection, and Fax emulation with Fax analysis. VQuad™ FXO services include Call Forwarding, Three-Way Calling, Call Waiting with Call ID, Call Transfer, and Call Hold. Tests include KPIs for Call Failure and Call Drop, One Way Delay and Round-Trip Delay measurements, and analysis of the incoming audio to determine if WB was sustained. In other words, the VQuad™ FXO solution provides full automation with enhanced scripting for testing multiple FXO ports for both functionality and voice analysis.  When combined with the 
WebViewer™ Central System all results and events can be saved directly to a Central Database and accessed using the WebViewer™ (direct access to the database tables is also available)”.

He further added, “The VQuad™ Command Line Interface (CLI) now supports remote accessibility and thus it facilitates controlling individual VQuad™ nodes located at various destinations. Also included is an API (SDK) for remote controlling the individual VQuad™ Nodes from within any application. The supporting commands include all Call Control functions as well as traffic generation/reception functions. Analysis is provided using GL’s Voice Quality Analysis (both POLQA and PESQ supported), Echo Measurement Utility (EMU), Fax Analysis, and Voice Band Analyzer (VBA)”.
