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.
