Overview:

GL's VQuad™ along with the Dual UTA makes assessing Voice Quality between and within differing networks easy, portable, and convenient. The system provides all necessary capability for automatic measurement of Voice Quality and QOS for any desired network including Wireless, VoIP, Analog, and TDM. The VQuad™ VQT System provides multiple interfaces for connecting to the Network using a single box solution. The single box solution enhances the user friendliness and the portability.

Dual UTA is a low power USB device that has been fully tested with an ultra-portable Dual Core NetBook (no external power required), which allows both the VQuad and VQT to reside and operate simultaneously on the same NetBook.

Available VQuad™ Interfaces:

Full support is also available for remote access of the VQuad™ and an SDK directly to the Dual UTA hardware (VQuad™ not required to be running).

Up to 8 devices (interfaces) can be controlled simultaneously on a single portable system. The system allows for independent traffic and independent automated Call Control via script configurations. This VQuad™ is fully automated, and when coupled with the GL VQT, the resultant MOS scores are automatically delivered to a remote client. A GPS option permits time synchronization between two geographically separated systems as well as location information for drive testing. Thus, VQT MOS scores as well as the Call Control information can be plotted to local street maps (most all countries supported). Finally, Round Trip Delay and One Way Delay measurements are provided directly via the Dual UTA hardware.

VQuad™ Testing Solutions

Truly Portable platform for VQuad™ and Dual UTA – NetBook PC

VQuad™ with the Dual UTA can be purchased with a NetBook PC for a truly lightweight portable solution. The Dual UTA is fully compatible with the miniature NetBook and allows the VQuad™ software to be installed for full testing without any performance issues.

The Dual UTA connected to the NetBook running VQuad™ provides up to 2 telephony instrumentations (via data cable or Bluetooth®) simultaneously. Used in conjunction with GL's VQuad™ software application, the Dual UTA simplifies end-to-end testing of voice quality, echo, noise, call failure rates, and other impairments of TDM, VoIP, and Wireless networks. A GPS sync port on the Dual UTA permits precise synchronization of sending and receiving audio functions, one-way delay (OWD), and round trip delay (RTD). The Dual UTA can be directed to automatically send and record sample voice files between nodes of a telephony network.

NetBook PCs are smaller and less expensive than traditional notebook computers. This miniature version of a laptop could be coined as a mini-notebook computer optimized for simpler computing tasks. It has a smaller screen, it’s lighter, and it normally has a longer battery life.

GL’s VQuad with Dual UTA purchased along with the NetBook PC can be conveniently packaged as a complete voice quality testing unit and shipped to intended location. The Dual UTA can be simply plugged into the NetBook PC using the USB connection. Up to two devices can be supported simultaneously on a Dual UTA (mobile phone, Bluetooth phone, Analog FXO, Phone Handset, PTT Mobile Radio) and up to two Dual UTAs can be supported in a single NetBook (thus allowing a maximum of 4 simultaneous devices). Both the GL VQuad™ and GL VQT applications can be remotely accessed via the Internet.

Network Setup

Automated Testing of Mobile Radio and Wireless Phones (Wi-Fi, WiMax, Bluetooth) using Dual UTA

Wireless networks can impair voice quality by various means including poor mobile phone quality, voice compression and decompression algorithms, delay, loss or gain in speech levels, noise, acoustic and landline echo, and other distortions. GL provides a compact and portable solution for Wireless phone and Mobile Radio testing.

Testing mobile end-to-end voice quality and provide VQT measurement results along with VQT analysis results
Mobile Phone call control – supports Bluetooth™, and 2.5mm Audio Headset Jack interfaces
Control Mobile Radios with Push-to-Talk functionality; Supports radio keying and send/record audio
Automatic One-Way Delay (OWD) & Round Trip Delay (RTD) measurements with results sent to GL VQT database
Synchronized software for sending/recording of voice files

Automated Testing of 2-Wire Analog interface (PSTN, ATA, Media Gateway) using Dual UTA

GL's VQuad™ with Dual UTA provides the solution for testing analog 2-wire interfaces (PSTN, ATA, Media Gateway). The Dual UTA supports 2 Analog FXO interfaces (RJ11) and provides Off/On- Hook, DTMF Dialing, Flash Hook, Tone Detection (Dialtone, Ringback, Busy, Fast Busy, SIT) and CallerID. The Dual UTA Analog interface supports two-stage dialing, IVR testing, Voice Quality Testing, Delay Measurements, and Echo Measurements. The product can be configured to automatically send/record a multitude of voice files and to perform VQT algorithms immediately after the voice file recording is complete.

Two Analog ports per Dual UTA (RJ-11 interface).

Each analog port may be controlled independently for traffic and call control

Automated Testing of VoIP (SIP) Interface, Digital VoIP Phones, VoIP Softphones using Dual UTA

With the growing requirements for voice quality testing within VoIP networks, a major concern is testing the VoIP Network, VoIP phones, VoIP Softphones, and the Analog Telephone Adaptors (ATA).

GL's VQuad™ with VoIP option, along with VQT, provides the ability to perform manual or automated tests on the VoIP network. The VQuad™ provides direct connection to the VoIP network with up to eight instances connected simultaneously. VQuad™ with Dual UTA provides the ability to test ATA’s and Softphones while connected to the VoIP Network.

Automated Testing of TDM T1/E1 Interface (CAS/PRI ISDN) using USB T1/E1 Analyzer

Voice quality is essential for all Networks as well as Gateways and Switches. Providing the mechanism for VQT over T1/E1 trunks is essential. The VQuad™ with TDM option includes the Ultra T1/E1 Analysis cards (PCI) or Portable USB T1 E1 Analyzer for a truly portable solution. Using the T1/E1 Analyzer, the VQuad™ can generate and receive up to 8 simultaneous CAS or PRI ISDN or No Call Control (NOCC) calls on T1 or E1 trunks. Once the call is up, sending/recording voice is provided via the VQuad™ traffic configuration yielding in VQT MOS results. The T1/E1 option includes a script based CAS State Machine for creating any desired CAS protocol. Included with the PRI ISDN are all variants associated with ANSI and ETSI specifications.

T1/E1 Network Support
Supports Call Control for PRI ISDN and CAS Protocols
Also supports No Call Control (NOCC), where the T1/E1 call is connected without any call control required.
Voice File sending/recording for VQT analysis
