Unified Circuit Card Size
All the circuit cards for 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 NEAX 2000 IPS are provided with 8 circuits per card. This allows the
physical system size to be compact.
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 NEAX 2000 IPS provides a maximum of 256 AP ports and it is independent of the 512 phyical
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.)
Remote PIM over IP with Survivability
The NEAX 2000 IPS can have a PIM installed at a remote site through an IP network. At the main site,
the NEAX 2000 IPS/NEAX IPS
installed at the remote site. The main site controls call processing and service feature access for
station users located at both the main and remote sites. When the Remote PIM cannot be connected
with main site due to the IP network and/or main PBX failure, the Remote PIM initializes the system and
re-starts operation by its own Main Processor (survival mode). In the survival mode, almost all service
features are provided to the station users accommodated in Remote PIM. When the IP network/main
PBX recovers, the Remote PIM can be restored to normal mode with a system initialization by manual
operation or automatically (Selectable by system data setting).
