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
U
NIVERGE
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.
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.)

IPS DM (
Internet Protocol Server Distributed Model)
is equipped with all
the features and functions of the
U
NIVERGE
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
U

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

NIVERGE
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
