CHAPTER 1 INTRODUCTION

This document provides an overview of the NEAX 2000 IPS (Internet Protocol Server) stored program control digital electronic PBX. An introduction to the technical characteristics is included, along with a description of available system applications.

System Overview

The NEAX 2000 IPS is a full-featured IP-based communications system providing a rich feature set of NEAX 7400 ICS M100MX*, with pure Voice over IP (VoIP) communications (peer-to-peer connections), across corporate Local and Wide Area Networks (LAN and WAN).

Figure 1-1 NEAX 2000 IPS

The NEAX 2000 IPS supports both pure IP switching (peer-to-peer connections) and Time Division Switching. The pure IP switching is provided for communications between DtermIPs and for CCIS connections with another NEAX 2000 IPS/2400 IPX (CCIS over IP). On the other hand, the TDM switching is provided for communication between legacy stations/trunks. Connections between DtermIP/CCIS over IP and legacy stations/trunks are made via IP PADs, which converts packet-based voice data to TDM-based voice data, and vice versa.

*“NEAX 7400 ICS M100MX” is marketed in North/Latin America and Australia as “NEAX 2000 IVS2” and in UK as “NEAX 2000 INTEGRATED VOICE SERVER.”
