GL Announces T1 E1 Quad and Octal Cards

Gaithersburg, Maryland, USA - GL Communications Inc. announced today the release of its newest T1 E1 Quad and Octal Analysis and Emulation hardware.

Speaking to reporters, Mr. Jagdish Vadalia Product Development Manager said, "GL's Octal & Quad T1 E1 boards are high density and provide Four (4) or Eight (8) RJ-48 T1 E1 ports and multiples thereof. For example, configurations of 8, 12, 16, and up to 64 T1 E1s in a single rack are possible."

He added, "The cards are available with user-friendly GUI for Windows® XP and Windows® 7 operating systems with support for almost all existing T1 E1 Analyzer applications including Comprehensive Analysis / Emulation of Voice, Data, Protocol, Digital, and Echo Testing."

Mr. Vadalia further added, "GL also offers other popular forms of T1 E1 analysis hardware such as Portable USB T1 E1 Analyzer with dual T1 E1 ports & smallest form factor, tProbe(TM) T1 E1 Analyzer Unit - an enhanced version of USB based T1 E1 VF & Serial Data analyzer with expansion capabilities, Universal T1 E1 Analyzer Boards - a dual port PCI based T1 E1 analyzer offering higher speed and smaller dimensions."

Important Applications/Features:

o T1 or E1 interfacing - Software Selectable

o TDM, ISDN, SS7 - High Density Voice

o VoIP, Frame Relay, Multi-Link Frame Relay, PPP, IMA, and Multi-Link PPP, HDLC

o Most all "basic applications" and "special applications" are available for Quad and Octal T1 E1 cards

o Call Recording, Generation, and Monitoring for hundreds to thousands of calls in one platform

o Windows® and Linux Drivers for Open Source Applications

o Media (VoIP) Gateway, IP PBX, and IVR Applications i.e. Asterisk (TM)

o Router with Multi T1 E1 WAN Interfaces i.e. ML-PPP (Multi Link PPP)

o PCI Express x1 Lane/Board

o "Cross-Port Through" and "Cross-Port Transmit" Modes - these configurations make cabling with Drop/Insert and Fail-Safe Inline Monitoring very easy

o High Density and High Speed - The boards (with Direct Memory Access) are significantly faster and significantly more efficient

o Octal boards are compatible with dual, quad, and higher core motherboards and software that simulate dual and quad cores (hyper-threading)

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.
