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 D
term IPs 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 D
term IP/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 IVS 2 ” and in UK as “NEAX 2000 INTEGRATED
VOICE SERVER.”
