Press Release: GL Enhances T1 E1 Analyzer Products / Software

Gaithersburg, Maryland, USA - February 9, 2011 - GL Communications Inc. announced today the release of T1 E1 Analyzer Software Version 6.0 along with new T1 E1 Hardware. Addressing the media, Mr. Vijay Kulkarni, CEO of the company said, "Our T1 E1 Analysis suite of products provides comprehensive analysis and emulation capabilities for voiceband analysis and signaling protocol analysis”.

He added, “Our new hardware called tProbe™ is an enhanced version of our USB based T1 E1 Analyzer. New software applications were also introduced to the T1 E1 line of products including ATM BERT, Simplified Audio Client (SAC), WCS - Client Data Tx Rx, and ASCII–TS Display Application to name a few. Significant enhancements were also introduced to existing applications, and they include Jitter Measurement & Pulse Mask, MAPS, Protocol Analyzers, and other Windows Client Sever based applications”.

Mr.Kulkarni further added, “The tProbe™ incorporates all the same features of the previous analyzer such as portability, USB interface, remote accessibility, scripting, and a vast set of optional applications. tProbe™ comes with “basic software” for basic testing needs and optional features that extend the capability far beyond the most expensive T1 E1 testers.

The new software application ATM BERT permits BER testing over ATM layer. It allows an ATM virtual circuit to be tested by sourcing test traffic and verifying at the receive end. Other features are: Bit Error Insertion, Looping back incoming traffic (using T1 E1 Loopback), and configuring ATM headers for UNI & NNI interfaces.

The newly added Simplified Audio Client (SAC) application supports a Simplified Audio (VF) Client (SAC) application to perform non-intrusive and intrusive VF monitoring, VF recording, and VF testing. SAC provides an alternate & simple GUI to perform analog Tx/Rx functions.

Our latest Client Data Tx Rx is an optional WCS Server side module that provides the capability for clients to Tx Rx T1 E1 data to from the Server. Now the client can transmit and receive files or T1 E1 data directly to the server. Its main functions are: receives raw data from T1/E1 line and sends it to the client as task data messages and receives data from the client via task data messages and transmits this data on T1/E1.

The new ASCII - TS Display application permits viewing of real-time ASCII events that are present on the T1 or E1. The ability to display the ASCII events for a particular port and timeslot is provided. Each event is properly time-stamped for tests that require time correlation. Logging real-time events to the hard drive is also possible”.

He added, “Enhancements introduced to Jitter Measurement & Pulse Mask , MAPS, Protocol Analyzers, Window Client-Server (WCS), WCS MLPPP Emulator, and MLPPPterr applications of the T1 E1 Analyzer product suite significantly enhances the user experience and adds value to the T1 E1 testing needs of the customers".

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) are all 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.
