GL Releases Enhanced T1 E1 Products and Software

Gaithersburg, Maryland, USA – GL Communications Inc. announced today the release of T1 E1 Analyzer Software Version 5.08 with new features and enhancements. Addressing a press conference, Mr. Vijay Kulkarni, CEO of the company said, “The T1/E1 Analysis Suite of products provides comprehensive analysis and emulation capabilities for voiceband analysis and signaling protocol analysis. The additions to the T1 E1 Analyzer product suite now include new features: Enhanced Bit Error Rate Tester, Multi-Channel Trau Emulation and Analysis using Client-Server, Near Real-Time Voice Band Analyzer (VBA), and MC-MLPPP Emulation using Client-Server”.

Mr. Kulkarni added, “A host of new features and enhancements are also added to the existing applications and are: Inverse Multiplexing in the ATM Protocol Analyzer, Multi-Channel HDLC Emulation / Analysis and File Based High Throughput HDLC Record/Playback, MC-MLPPP bundle decode capability in MLPPP Analyzer, AMR-WB codec support in TRAU Emulator, and Enhancements to T1E1 Client-Server application”. He further added, “With the introduction of the new applications and enhancements, the T1E1 Analyzer Product suite adds significant value to T1 E1 testing needs of customers”.

A brief summary of the new features in the T1E1 Analyzer - 5.08 Release are provided below:

•Enhanced BERT

This application differs from basic BERT by allowing the users to perform error testing on multiple cards simultaneously. Users can define the bit pattern, and error rate (Ranging from 0.01 to 1e-009). It provides detailed view of result including total errors, error rate, degraded minutes, and so on

•Multi-Channel TRAU Transmit/Receive Emulation and Analysis using Client-Server

The Multi-Channel TRAU Emulation and Analysis (TrauTerr) module allows testing of TRAU frames. The frames will be generated based on the codec type, impairments, time alignment (if specified), and then transmitted through the 16 or 8 kbps channels.

•Near Real-Time Voice-Band Analyzer (VBA)

The Near Real-Time Voice-Band Analyzer (VBA) is an analysis tool for monitoring voice band traffic over VoIP, TDM, and Wireless networks. VBA instantly detects voice file captures and with appropriately installed analysis modules, monitors speech levels, noise levels, line echo, and acoustic echo.

•WCS MC-MLPPP Emulator

The Multi-Class extension to Multi-Link PPP emulator allows a sender to fragment packets of various priorities into multiple classes, and send high-priority packets between fragments of lower priorities.

Other significant enhancements Introduced to the following applications:

•ATM Analyzer

ATM Analyzer is enhanced to capture & reassemble frames that were transmitted with Inverse Multiplexing applied. IMA combines multiple T1 or E1 links to form a single high-speed connection. IMA provides flexible bandwidth options to achieve rates between the DS1/E1 and DS3/E3.

•Multi-Channel HDLC Emulation Analysis and File based High Throughput HDLC Record/Playback

GL's HDLC Analyzer now supports both contiguous and non-contiguous transmission and reception of signals that include CRC-NONE, CRC16, and CRC32 options, and also BITSYNC, and OCTETSYNC options. More sample scripts are included for assisting users in analysis & emulation.

•MLPPP Analyzer

The MLPPP Analyzer application has been now added with MC-MLPPP decoding ability. It provides the option to add or delete one or more bundles under stream/interface selection feature.

•TRAU Emulation

The TRAU Toolbox™ now supports AMR -WB codec with data rates of 6.60 kbps, 8.85 kbps, and 12.65kbps. There are also sample scripts included for assisting users in emulation.

•T1E1 Analyzer Enhancements

The T1E1 Analyzer software supports HD PCI cards and portable USB units. Every USB board is required to be licensed with T1 (or E1) basic software for executing the Analyzer Software.
