Newsletter: GL Announces T1E1 Quad & Octal Analysis & Emulation Hardware

Welcome to a February 2012 issue of GL Communications’ Newsletter providing information and insight into our latest T1 E1 Quad and Octal Analysis and Emulation Boards.

Overview

GL's Octal & Quad T1 E1 boards are high-density boards that provide Four (4) or Eight (8) RJ-48 T1 E1 ports and multiples thereof. For example, configurations of 8, 12, 16, …64 T1 E1s in a single rack are possible.

Important Applications / Features:

  • T1 or E1 interfacing – Software Selectable

  • TDM, ISDN, SS7 – High Density Voice

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

  • Most all “special applications” are available for Quad and Octal T1 E1 cards

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

  • Windows® and Linux Drivers for Open Source Applications

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

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

  • PCI Express x1 Lane/Board

  • “Cross-Port Through” and “Cross-Port Transmit” Modes – these configurations make cabling with Drop/Insert and Fail-Safe Inline Monitoring very easy

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

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

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.

Comparison and advantages of the new Quad and Octal Cards over Dual T1 E1 Universal Cards are given in the following table.
