1 • Introduction Model LRA2900A RAS Getting Started Guide

Software overview

The Black Box Model LRA2900A supports all common remote access services as well as integrated routing and forwarding (see table 3). Authentication and network management offer control and detailed monitoring from any web browser. From the PSTN, the Model LRA2900A RAS will accept either T1/E1 or PRI connections, with support for both channel associated or common channel signaling.
