GL Announces Simplified VoIP Testing
Gaithersburg, Maryland, USA - September 15, 2009 - GL Communications Inc., announced today the release of VoIP Testing Solution with VQuad(TM)- an easy, automated, or manual means to testing end to end VoIP performance. Speaking to media persons, Mr. Robert Bichefsky, senior manager said, "Testing at the end-points of a VoIP network is a true reflection of the voice quality that an end user is actually experiencing. The VQuad(TM) with Dual UTA can connect and test VoIP networks at endpoints in many ways:
Direct Ethernet connection using SIP (Session Initiation Protocol)
Dual UTA / 2Wire connection to an ATA or router
Dual UTA / RJ-22 (curly cord) handset interface
Dual UTA / 4-Wire sound card interface for IP Softphones
Bluetooth to a mobile phone
He added, "VQuad(TM) can perform manual or automated tests on up to eight VoIP sessions simultaneously. Important features include: automatic call control (SIP protocol), automatic traffic generation/reception, and path confirmation using digits or frequency tones".
Mr. Bichefsky further added, "VQuad(TM) along with the Dual UTA can connect to a VoIP network in several ways including through an ATA (the Dual UTA simulates the analog phone), through a Softphone (the Dual UTA provides Balanced I/O ports), via wireless (the Dual UTA connects to any mobile phone using Bluetooth® technology), and through the customer's phone itself (the Dual UTA can replace the handset of ANY analog, digital, or VoIP phone). The VQuad(TM) can also act as an end point and directly connect to the VoIP network via SIP protocol".
He added, "When simulating VoIP end points, as a user agent or thru the analog 2-wire interface, VQuad(TM) supports full call control including supplementary services such as 3-Way Calling. VQuad(TM) also supports path confirmation, send/record voice synchronously for VQT PESQ results and full scripting of the test. Additional measurements include Round Trip Delay, One Way Delay and a variety of functions for echo testing".
Important features
Connect and simulate any endpoint
Connect directly to ATA, Router, Softphone, Phone Handset, or Wireless via Bluetooth®
Connect at using SIP protocol with user-defined parameters for Authentification and Proxy
Connect up to eight interfaces with a single VQuad(TM) system
Connect manually or automatically with SIP call control and user-defined parameters for authentification and proxy
Perform numerous measurements including PESQ, latency (including RTD and OWD), Post Dial Delay (PDD), and Signal to Noise Ratio (SNR), and many others
About GL Communications Inc.
Founded in 1986, GL Communications Inc. is a leading supplier of test, monitoring, and analysis equipment for TDM, Wireless, IP and VoIP networks. Unlike conventional test equipment, GL's test platforms provide visualization, capture, storage, and convenient features like portability, remotability, and scripting.
GL's TDM Analysis & Emulation line of products includes T1, E1, T3, E3, OC-3, STM-1, analog four-wire, and analog two-wire interface cards, external portable pods, and complete system solutions. Capabilities include voiceband traffic analysis and emulation across all traffic types (voice, digits, tones, fax, modem), all protocols (ISDN, SS7, GR-303, Frame Relay, HDLC, V5.X, ATM, GSM, GPRS, etc.), and with capacities up to thousands of channels.
GL's VoIP and IP products generate / analyze thousands of calls / traffic simultaneously with traffic types such as frames, packets, voice files, digits, video, tones, noise, and fax using G.711, G.729, AMR, EVRC, GSM and a range of other codecs. Additional features include visual analysis, real-time listening, and recording. 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 excepted solution across the telecom industry. Voice Quality Testing across multiple networks (T1, E1, T3, E3, OC-3, VoIP, Wireless, and Landline) are all available.
GL's Wireless Products perform protocol analysis and voice quality assessment on GSM, CDMA and UMTS 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 compliance testing per G.168 and G.160 across TDM, IP, VoIP and Wireless networks. 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 intelligence. Centralized or distributed access, efficient transport and database loading allow compatibility with 3rd party and standards based monitoring systems.
