INTRODUCTION
Extended Application Processor (AP) Port Capacity
The NEAX 2000 IPS provides a maximum of 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 the 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.
Various Power supply system
AC Input system
The PIM houses the AC/DC power supply with various AC (100V/200V) input that outputs various DC
voltage required for several internal cards.
The AC/DC power supply has function of Battery charger. Thus, system can be backed up with battery
according to necessity.
The PIM also houses optional DC/DC power supply for the cards that require -48V power such as CSI
card used for interface of cell station/zone transceiver.
DC Input system
NEAX 2000 IPS also provides the DC/DC power supply with -48V DC input house in the PIM that
outputs various DC voltage required for several internal cards.
Thus, NEAX 2000 IPS can be installed at various powering environment.
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
