NEC 2000 IPS manual Universal Slot, DC/DC Power Supply for, Dual MP System

Chapter 1 Introduction

Universal Slot

One PIM provides 12 card slots for Line/Trunk (LT). Also, these card slots can be used for Application Processor (AP) cards without complicated limitations. As this makes easy quotation and installation, more number of AP cards can be mounted in one PIM.

DC/DC Power Supply for –48V

The PIM houses optional DC/DC Power Supply for the cards which require –48V power such as CSI card used for interface of Cell Station (CS) of wireless system. Since this power supply is mounted in the space under the AC/DC power, additional Power Module/card slots are not required.

Extended Application Processor (AP) Port Capacity

The UNIVERGE NEAX 2000 IPS provides a maximum of 256 AP ports and it is independent of the 512 physical ports for legacy Line/Trunk (LT), therefore, more AP cards can be used in the system such as T1/E1 digital link, etc.

Dual MP System

The system complies with dual control system on Main Processor.

Note: Since the system employs Cold Standby processing in MP changeover, the calls in progress are terminated as a result of the MP changeover. Also, during the MP changeover, the call originating/receiving and service feature access are not effective. (It takes about 30 to 60 seconds to complete the MP changeover.)

UNIVERGE NEAX IPS DM

The UNIVERGE NEAX IPS DM (Internet Protocol Server Distributed Model) is equipped with all

the features and functions of the UNIVERGE NEAX 2000 IPS, with a smaller space requirement. It is a full-featured PBX that supports advanced networking, pure peer-to-peer IP telephony connectivity and traditional TDM switching capabilities. Designed primarily for pure

converged IP networks, the UNIVERGE NEAX IPS DM can also accommodate a mixed (i.e., TDM and IP) converged IP network or standalone solution.

The UNIVERGE NEAX IPS DM supports up to 952 peer-to-peer IP stations and 56 TDM ports in a single modular chassis. Up to two chassis can be stacked providing maximum capacity of 112 legacy TDM ports while still supporting as many as 888 peer-to-peer IP stations or more depending on the amount of TDM stations used. It uses the same CPU, line/trunk cards,

application processor cards and software of the UNIVERGE NEAX 2000 IPS and comes equipped for 19” rack mounting. It offers superior port density; each chassis only occupies two Rack Units (2RU).
