NEAX 2000 IPS General Description Page 13
NDA-24345, Issue 3
Enhanced Built-in Firmware Processor (FP) on MP
The Firmware Processor card (FP) provides Line/Trunk interface, Memory (RAM 768 KB), and
inter-module BUS interface. BUS interface functions as a driver/receiver of various signals, adjusts
gate delay timing and cable delay timing, and monitors I/O Bus and PCM BUS. When the system
consists of three PIMs or more, one each of this card is mounted respectively in PIM 2, PIM 4, and
PIM 6.
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 AP cards such as T1/E1 digital link cards can be used in the
system.
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 limitation. This makes easy quotation and
installation, and more AP cards can be mounted in one PIM.
Unified Circuit Card Size
All circuit cards for the 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
The major line/trunk cards used in the NEAX 2000 IPS are provided with 8 circuits per card. This
allows the physical system size to be compact.
DC/DC Power Supply for –48V
The PIM houses optional DC/DC Power Supply for the cards which require –48V power such as the
CSI card used for interface of Zone Transceiver of wireless system. Since this power supply is
mounted in the space under the AC/DC power, no additional Power Module/card slots are required.
Built-in DRS (Device Registration Server) on MP
The NEAX 2000 IPS incorporates DRS (Device Registration Server) on the MP. DRS provide Log-
in/Log-out management of DtermIP including Registration and Authentication. Also, the built-in
DRS can be inter-worked with DHCP server to provide easy administration on IP address.
Office Data Backup Enhancement
The office data of the NEAX 2000 IPS is stored in Flash ROM; therefore the backup period is
extended compared with previous IVS series which were using RAM with battery.
Various Installation Methods
To meet the specific needs of the customer’s environment, the NEAX 2000 IPS provides the
following installation methods:
 Floor Standing Installation
 Wall-mounting Installation
 IEC standard 19 inch Rack-mounting Installation
