(1888PressRelease) August 21, 2012 - Gaithersburg, Maryland, USA - Speaking to reporters, Mr. Vijay Kulkarni CEO of the company said, "LinkTest™ DUAL E1 is a user-friendly, hand-held, battery operated, E1 test and measurement device with standard basic features plus sophisticated Jitter, Wander, and Datacom testing options and comes with a very low cost. One unit provides most if not all the testing features you may need in the field to make troubleshooting easy and quick."

He added, "GL's LinkTest™ DUAL E1 is a hand-held dual-port tester for E1 and data communications (V.11 / X.24, V.24/RS232, V.35, V.36/RS449, EIA-530, EIA-530A) interfaces. Port A is full-featured 2048 kb/s interface. Port B usage is configurable (2048 kb/s TX/RX, co-directional, or for clock input). It has an external DC input and internal rechargeable batteries. This makes the tester suitable for field-testing applications.

With the support of a large range of software options for E1 services and sub-rate multiplexing, the LinkTest™ DUAL E1 unit provides a scalable test solution for E1 and datacom testing. It provides a large, clear screen with a full set of physical layer tests for E1 balanced and unbalanced circuits including BERT, VF, round trip delay and signal level."

Mr. Kulkarni further added, "The tester is simple to use and rugged - perfect for installation, commissioning and maintenance of digital networks. The unit is an excellent tester for network operators, contractors and enterprise users who have to manage fixed and mobile networks that are using E1 and Datacom back-haul circuits.

The main applications include digital voice and data testing, jitter measurement, wander measurement, and pulse mask compliance. The tester can be used for maintaining and troubleshooting PDH, synchronization, and datacom links."

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) 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.
