AdvantagesChapter 1  Introduction
3. Flexible Line Size-Innovative Modular hardware and software design allows the
NEAX2000 IVS2 to efficiently serve from 24 ports up to 512 ports. Modularity
gives the system the ability to expand from its minimum configuration to its
maximum capacity as the need arises. This unique expansion capability allows the
system to grow in a cost affective manner as the user requirements expand. Your
initial system investment is protected through growth capability.
4. Energy Saving and Space Savings - Through employment of state-of-the-art
technology in the system circuitry design, NEC has been able to reduce power
consumption. As a result, the current consumption of the system has been reduced
to 50% of that of any conventional electronic PBX systems. This energy saving
oriented system design allows for the use of much smaller capacity main power
equipment and air conditioning equipment. In parallel with the energy savings, the
space requirement for the system has been reduced to one third when compared
with that of a conventional electronic PBX system.
5. Building Block Configuration - In a conventional switching system, various kinds
of equipment are mounted in a cabinet group and are connected to each other by
use of connecting cables. The NEAX2000 IVS
2, however, uses a building block
modular design. When installing the system, the required blocks are placed on top
of each other in a building block formation and interconnected by round bus
cables.
6. Flexible Interface Ports - The NEAX2000 IVS
2 employs a Universal Port
architecture that has the flexibility to accommodate station terminal equipment,
trunks and adjunct processors. This universality allows the NEAX2000 IVS
2 to
maximize slot space use and lower expansion costs.
7. High Reliability - The NEAX2000 IVS
2 is designed and manufactured to provide
the highest level of system reliability. The NEAX2000 IVS2 is designed with such
features as: remote maintenance, distributed call processing, error-correcting
memory, battery backup, and automatic system alarm indications to ensure
unsurpassed reliability. Only the finest components have been used. In addition,
through the employment of LSI and custom LSI and VLSI technology, the
number of component parts has been greatly reduced, thus lessening possible
failures and insuring continuous operation.
8. Intelligent Attendant Console - The NEAX2000 IVS
2 attendant console, SN716
Desk Console, is a compact, desktop unit equipped with non-locking keys, Light
Emitting Diodes, and a 4 x 40 character Liquid Crystal Display.

The LEDs provide continuous information relative to the status of calls in
progress. The display provides station and trunk identification, class of service
and the number of calls waiting. The LCD changes with different call states and
instructs the user which Multifunction keys are available for each state. Keys such
as Busy Verify, DND Override, etc. only appear when needed. The Multi-function
Keys reduce the number of different buttons and greatly simply operation.
9. Intelligent Digital Multifunction Terminal - In addition to supporting
conventional station equipment, the NEAX2000 IVS
2 can be equipped with the
Dterm series digital electronic multifunction terminals. The Dterm terminals are
intelligent microprocessor controlled terminals, which enhance the feature
capabilities offered by the system and provide the service of conventional key
telephones over 1-pair wiring. The D
term instrument may be equipped with an
interface adapter to allow simultaneous voice and data switching, without
compromising the voice communication system.
10. Ease of Installation - Because the NEAX2000 IVS
2 uses pre-assembled modules
and plug-in type circuits packs, it is easy to install. Wiring connections, both
internal and external, are made through simple-to-use standard plug-ended cables.
In addition, with each unit and system having been fully factory tested prior to
shipment, potential obstacles to easy installation have been held to a minimum. 
11. Ease of Maintenance - Because the system is constructed with first quality
components, reliability is high and operation is trouble free. However, should a
minor fault occur, the self diagnostic programs will detect the fault, and
automatically make the needed corrections. If the problem is beyond the internal
correction capabilities of the system, the self diagnostic programs will
automatically print the nature of the fault and the involved unit is identified on the
man-machine interface equipment. The faulty plug-in unit can then be quickly
replaced with little or no interruption of service.
12. Flexible Numbering Plan - The NEAX2000 IVS
2 provides flexible numbering
assignment to meet all forms of network integration service.
13. Future Capabilities - Because the NEAX2000 IVS
2 uses a stored program control,
performance enhancements and new features can be easily incorporated by simple
changes in software. The NEAX2000 IVS
2 can be upgraded by using the most
current software release and, when necessary, additional hardware. This means
that the system will not become obsolete.

 Flexibility
 Capacity
 Reliability
 Optimum space use
 Minimal environmental requirements
 Ease of installation and maintenance
A unique modular design is employed throughout the NEAX2000 IVS
2. As additional
equipment modules are required, they are stacked on top of each other, rather than
mounting the equipment in conventional frames or cabinets. This innovative method
reduces installation time, avoids the use of bulky frames and provides for manageable
future expansion, virtually eliminating the possibility of outgrowing your
NEAX2000 IVS

Chapter 2 System Configuration
The NEAX2000 IVS2 consists of 1 to 8 Port Interface Modules (PIMs), each PIM will
support up to 64 interface ports to give a maximum capacity of 512 ports per system.
The PIMs are all the same with a universal back plane, which accommodates station
ports, trunk ports, I/O processors, and power supply boards. Each PIM measures 16.9
inches across by 16.4 inches high by 8.8 inches deep (includes front cover). This
compact frame allows the system to be mounted on a wall, in a 19 inch rack, on a
desk/bench, or bolted to the floor. 
PIM units contain the following components.
1. Line/Trunk Interface Slots
Line and trunk interface slots house the digital and analog interface cards. The
NEAX2000 IVS
2 uses the PIM-F.
 The PIM-F has 15 slots. 12 slots (LT00-LT11) each can be used for either LT
or AP cards. 1 dedicated slot (MP12) for MP or FP, 1 dedicated slot (PFT) for
Power Failure Transfer card, and 1 dedicated slot (VM) for voice mail card. 8
port Line/Trunk cards can be mounted in LT00 to LT07 slots. 4 port
Line/Trunk cards can be mounted in LT00 to LT10 slots. LT11 slot is
available for 4 port Line/Trunk cards only when the system is configured with
two or less PIMs.
2. Power Supply Board
Each PIM is equipped with a Main Power Supply card (PZ-PW121) which
converts AC120V/240V (50Hz/60Hz) to -27V DC (4.4A), +5V (7.2A), CR
(38mA), +90V (80MA).   
3. Application Processor (AP) and Common Control Slots
Application processor cards use AP slots in each PIM. The number of available
AP slots depends on the PIM number and which common control cards are needed
for that PIM. The PIM-F has up to 12 AP slots. AP Slots are used to house the
processor boards for SMDR, OAI, T1, ISDN, CCIS, and others. Common control
cards such as the CPU, Bus cards, and local processors occupy only a set number
of AP slots.
4. Power Failure Transfer (PFT)
Two methods are used to provide Power Failure Transfer: (1) Using the
designated circuit card (PZ-8PFTB) which mounts in PFT slot of each PIM to
provide up to 64 trunk to station switch over points and (2) Utilizing the front
edge cable and connecting between 4COT card and AUC card.
