Automated VED Testing Method 1

The Auto VED Test Software is a feature rich application that uses GL Communications' T1 E1 Analyzer products to perform Automated Voice Enhancement Device testing in accordance with G.160 and G.169 ITU test requirements

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 Automatic Voice Enhancement Device Compliance Testing Solutions Per G.160 and G.169.

Speaking to media persons, Mr. Vijay Kulkarni CEO of the company said, ” The Auto VED Test Software is a feature rich application that uses GL Communications' T1 E1 Analyzer products to perform Automated Voice Enhancement Device testing in accordance with G.160 and G.169 ITU test requirements.”

He added, “There are two methods of testing voice enhancement devices, and are: File Based Approach, and Real-time Approach. The file-based approach method transmits files to Sin and Rin of the VED and captures responses at Sout and Rout. With this method, the Sin is pre-created from the Rin signal. This method assumes that Rout is identical to Rin. This works perfectly for TDM based Line Voice Enhancement Devices. This could also be used to test VEDs within Gateways in VoIP or VoATM environments as long as the delay between gateways is constant and Rout=Rin is valid. When testing VEDs within Gateways, a configuration of back-to-back Gateways is necessary to access the TDM side of each Gateway. The Real-Time Approach method creates Sin in real-time from the Rout. It is applicable to TDM, VoiP, and VoATM Networks. Windows Client Server (WCS) Software is used to perform real-time functions.”

Important Features:

·MS-Windows OS (Win 2000 or NT) with User-Friendly Graphical User Interface
·Compatible with GL's well proven UltraT1 E1 PCI Cards or Laptop T1 E1 Portables
·Real-time as well as off-line analysis
·Auto analysis of the response according to G.160 and G.169 requirement
·Tabular Pass/Fail Results
·Detailed graphical results for individual test, overall test

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, OC-12, STM-1, STM-4, 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, LTE, etc.), and with capacities up to thousands of channels. Our newest products provide astonishing capacity and capture capability up to and including gigabit speeds.

GL’s VoIP and IP products generate / analyze thousands of calls and traffic simultaneously with traffic types such as frames, packets, voice files, digits, video, tones, noise, and fax. Almost all codecs are supported including G.711, G.729, AMR, EVRC-A,B,C, GSM, iSAC, and many more. 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 accepted solution for assessing voice quality in the telecom industry. Voice Quality Testing across multiple networks (T1, E1, T3, E3, OC-3, OC-12, VoIP, Wireless, and Landline) is available.

GL’s Wireless Products perform protocol analysis and voice quality assessment on GSM, CDMA, UMTS, and LTE 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 line and acoustic echo. GL’s compliance testing per G.168. G.167 and P.340 across TDM, IP, VoIP and Wireless networks is widely accepted in the industry.

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 characteristics. Centralized or distributed access, efficient transport and database loading allow compatibility with 3rd party and standards based monitoring systems.
