1 Introduction

This document provides a configuration guide to assist Nortel Networks BCM

administrators in connecting to AT&T IP Flexible Reach service.

This document does not describe procedures to configure the BCM for

advanced functionality. For more information and procedures, please

refer to the Nortel technical documentation found on the Nortel

website.

1.1 Pre-IP PBX Configuration Activity

This guide assumes that the administrator is knowledgeable in IP PBX

programming and operations.

An important tool that the administrators should have at their disposal prior to

testing their IP PBX with IP Flexible Reach is the Wireshark network protocol

analyzer. This software can be used to run traces on problem calls so the

information can be shared with equipment and network engineers. This free

software can be obtained at http://www.wireshark.org/.

The customer may also use TCPDUMP which can be found on most UNIX and

Linux systems. The customer should have Wireshark or TCPDUMP loaded on a

server that is connected to a LAN switch or hub that can monitor both the

signaling and media packets on any calls between the customer PBX and the IP

Flexible Reach managed router.
