NEC 2000 IPS manual Built-in DRS Device Registration Server on MP, Office Data Backup Enhancement

Chapter 1 Introduction

Hybrid System of IP (peer-to-peer connection) and TDM Switching

The UNIVERGE NEAX 2000 IPS supports both pure IP switching (peer-to-peer connections) and Time Division Switching (TDM). The pure IP switching is provided for communications between DtermIPs and for CCIS/Remote PIM connections with another UNIVERGE NEAX 2000 IPS/IPS DM/IPS DML/2400 IPX (CCIS over IP or Remote PIM over IP). On the other hand, the TDM switching is provided for communications between legacy stations/trunks. Connections between DtermIP/CCIS or Remote PIM 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.

Built-in DRS (Device Registration Server) on MP

The UNIVERGE NEAX 2000 IPS incorporates DRS (Device Registration Server) on MP, which provides

aLog-in/Log-out management of DtermIP including Registration, Authentication. Also the built-in DRS can be inter-worked with DHCP server to provide easy administration of IP address.

Reduced Hardware with IP based Architecture

The DtermIPs accommodated in a LAN do not require a DLC card because they can be interfaced directly with the LAN and connected on a peer-to-peer basis. When a DtermIP is connected with station/trunk, which is accommodated in TSW, the speech path between LAN and TSW is made via IP PAD under the call processing control of MP. The number of DtermIPs can be simply expanded by adding the terminal itself, an IP Seat License and IP PADs if traffic volume is increased. With this system architecture, the hardware such as DLC, PIM, Power Supply etc. is reduced and easy cost effective move, add, change is realized.

Office Data Backup Enhancement

The office data of UNIVERGE NEAX 2000 IPS is stored in Flash ROM.

Various Installation Methods

To meet the specific needs of the customers’ environment, the UNIVERGE NEAX 2000 IPS provides the following installation methods:

Floor Standing Installation

Wall-mounting Installation

IEC standard 19-inch Rack-mounting Installation

Unified Circuit Card Size

All the circuit cards for UNIVERGE NEAX 2000 IPS are designed in one size (PN-type), and installed in the PIM. This maximizes the efficiency of slot utilization of the PIM.

High Density Line/Trunk Cards

Major line/trunk cards used in UNIVERGE NEAX 2000 IPS are provided with 8 circuits per card. This allows the physical system size to be compact.
