NEAX 2000 Internet Protocol Server (IPS) is a full-featured IP-based
communications system providing a rich feature set of existing NEAX 2000 IVS
with pure Voice over IP (VoIP) communications (Peer-to-Peer connections), across
corporate Local and Wide Area Networks (LAN and WAN).
Dterm IP telephones are designed to provide a converged infrastructure at the desktop,
with a 100 BASE-T Ethernet connection to the LAN and built-in hub for a PC
connection to the telephone itself. The system can provide Peer-to-Peer connections
between Dterm IP telephones with voice compression, offering existing Dterm Series
E telephone features. In a WAN, the system can provide Peer-to-Peer connections
over IP networks with voice compression through CCIS (CCIS over IP).
The NEAX 2000 IPS can provide Legacy station/trunk interfaces to support the
existing Time Division Multiplexing (TDM) based infrastructure, such as analog
telephones, analog networks, and digital networks (T1/E1 and ISDN). The Legacy
station/trunk interface cards (LT and AP cards) can be accommodated in the Port
Interface Module (PIM), in the same manner as the NEAX 2000 IVS
configuration, the NEAX 2000 IPS supports 512 LT ports which can be 448 Dterm IP
telephones and 64 Legacy LT ports, and 256 ports for Legacy AP cards.
Communications between Legacy stations/trunks and Dterm IP telephones/IP
networks are made via IP PAD, that converts packet-based voice data to TDM-based
voice data, and vice versa. The new Main Processor (MP) card controls both
Peer-to-Peer connections and TDM-based connections. The new MP card
incorporates a built-in Device Registration Server (DRS) and single interface point of
IP connections to IP telephone, MATWorX, and OAI/ACD servers.

Highlights
NEAX 2000 IPS highlights are as follows:
•Hybrid System of IP (Peer-to-Peer connection) and TDM Switching
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 Dterm IP telephones and for CCIS network with
another NEAX 2000 IPS/2400 IPX (CCIS over IP). On the other hand, the TDM
switching is provided for communications between Legacy stations/trunks.
Connections between Dterm 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.

•One-board Main Processor (MP) with Integrated Functionality
NEAX 2000 IPS Main Processor (MP) is the heart of pure IP connections and
TDM-based connections. The MP employs a high-speed CPU, which is
equivalent with Pentium. With this processing power and System On Chip (SOC)
technology, the MP integrates Device Registration Server (DRS), AP01 (OAI)
functions, which are provided by an additional card in the previous NEAX 2000
IVS series. Also, by means of LSI technology, the MP card size is minimized and
an Ethernet Interface Card is mounted on the MP without using an additional slot
space in the PIM. This interface card is linked with LAN for call control
processing of Dterm IP and inter-work with MATWorX and OAI server.

Chapter 1 IntroductionNEAX 2000 Internet Protocol Server (IPS)
•Built-in Device Registration Server (DRS) on MP
The NEAX 2000 IPS incorporates the DRS on the MP, which provides
Log-in/Log-out management of the Dterm IP including Registration,
Authentication. Also, the built-in DRS can communicate with the DHCP server to
provide easy administration of IP address.
•Enhanced Built-in Firmware Processor (FP) on MP
NEAX 2000 IVS2 requires FP card in PIM 0 when the system configured with
three or more PIMs. In the case of the NEAX 2000 IPS, an FP in PIM 0 is not
required since the Built-in FP function in the MP has been improved, providing
more call processing capability. (FP is used in PIM 2, 4 and 6.)
•Migration Path for NEAX 2000 IVS2
For the customers who are using NEAX 2000 IVS2, the migration path is
supplied. By replacing the existing MP card to a new one, the NEAX 2000 IVS
can be upgraded to IP/TSW Hybrid System including new and enhanced service
features introduced with the NEAX 2000 IPS. If a user wants to implement
Peer-to-Peer connection services, it is available by adding the IP PAD to the
existing system with the new MP.
•Reduced Hardware with IP based Architecture
The Dterm IP telephones accommodated in LAN do not require a DLC card
because they can be interfaced directly with LAN and have Peer-to-Peer
connection. When a Dterm IP is connected with a station/trunk, which is
accommodated in the TSW, the speech path between LAN and TSW is made via
IP PAD under the call processing control of MP. The Dterm IP can be expanded
by adding the terminal itself and IP PAD if traffic volume is increased. With this
system architecture, the hardware (DLC, PIM, and Power Supply) is reduced.
This makes moves, adds, and changes easier.
•Office Data Backup Enhancement
The office data of NEAX 2000 IPS is stored in Flash ROM. Therefore the backup
period is extended compared with previous NEAX 2000 systems that used RAM
with battery.
To meet the specific needs of the customer’s environment, NEAX 2000 IPS
provides the following installation methods:
•Floor-standing Installation
•Wall-mounting Installation
•IEC standard 19-inch Rack-mounting Installation
All the circuit cards for NEAX 2000 IPS are designed in one size (PN-type), and
installed in the PIM. This ensures that slot space is used efficiently within the
PIM.
Page 5
NEAX 2000 Internet Protocol Server (IPS)Chapter 1 Introduction
•High Density Line/Trunk (LT) Cards
Major Line/Trunk cards used in NEAX 2000 IPS are provided with eight circuits
per card. This allows the physical system size to be compact.
•Universal Slot
One PIM provides 12 card slots for Line/Trunk (LT). These card slots can also be
used for Application Processor (AP) cards without complicated limitation. As this
makes easy quotation and installation, more number of AP cards can be mounted
in one PIM.
•DC/DC Power Supply for -48 V
The PIM houses an optional DC/DC Power Supply for the cards that require -48 V
power (such as the CSI card, used as the interface for a wireless system’s Zone
Transceiver). Since this power supply is mounted in the space under the AC/DC
power, no additional Power Module/card slots are required.
•Extended Application Processor (AP) Port Capacity
The NEAX 2000 IPS provides maximum 256 AP ports and it is independent of
the 512 ports for the Line/Trunk (LT). Therefore, more number of AP cards can
be used in the system such as T1/E1 digital link.

Chapter 2System Configuration
Port Interface Modules (PIMs)
NEAX 2000 IPS consists of a number of Port Interface Modules (PIMs) depending on
the system configuration. There are two types of PIMs:
•Physical PIM
•Virtual PIM
The Physical PIM is a hardware PIM and is used to accommodate an MP, FPs, IP
PADs, Legacy LT and AP cards, and power supply units. One Physical PIM provides
up to 64 LT ports.
The Virtual PIM is a software PIM and is used to assign Dterm IP telephones by
system programming (The Physical PIM can be used to assign Dterm IP telephones,
but is not essential.). One Virtual PIM provides up to 64 Dterm IP telephones. The
system consists of up to eight PIMs, by the combination of Physical PIMs and Virtual
PIMs, thus providing a total of 512 ports for Dterm IP telephones and Legacy LT
cards. Total number of ports for Dterm IP telephones and Legacy LT cards must be
less than 512, so the number of Physical PIMs decreases when that of Virtual PIMs (=
number of Dterm IP telephones) increases.
Example: When 256 Legacy LT ports are required (= four Physical PIMs), the
maximum number of Dterm IP telephones is 256.
Figure 2-1 shows examples of 512-port configuration by the combination of Legacy
The NEAX 2000 IPS is an IP communication system that integrates the voice
terminals to the IP network through Peer-to-Peer connection.
The system is a hybrid system to accommodate both IP multi-line terminals (Dterm
IP) and the terminals used in Legacy PBXs (Legacy terminal).
Line/Trunk cards and Application Processor cards can be mounted in the system to
provide the features that are provided by Legacy Time Division Switch (TDSW)
PBXs.
