Hardware Architecture
Chapter 1 Introduction
Hardware Architecture
The NEAX2000 IVS
2
employs the latest advancements in Large Scale Integration
(LSI) circuits and component manufacturing techniques to create a highly reliable and
serviceable communications system.
The NEAX2000 IVS
2
architecture consists of three major functional components:
Distributed Controller, Digital Switching Network, and Port Interface.
1. Distributed Controller
The Distributed Controller is composed of distributed multiprocessing units,
generic memory, database instructions, system interface, and interface ports for
system maintenance and administration.
2. Digital Switching Network
The Digital Switching Network consists of a non-blocking digital time division
switch, allowing all ports to be used simultaneously.
3. Port Interface
The Port Interface provides access to the public and private network for various
types of terminal devices, including digital and analog telephones, data terminals,
computers and subsystems such as Voice Mail Systems, Data Switch Networks,
and related communication and information services.
Hardware
Modularity
The NEAX2000 IVS
2
continues with the modular design employing interface
modules in groups of 64 ports. The system allows users to purchase just the station
and trunk capacity that they need, yet expand that capacity by simply adding modules
to accommodate added demand. The modular design of the NEAX2000 IVS
2
allows
the system to grow from 24 to 512 ports. Hardware modularity results in one of the
most reliable, flexible, and powerful systems available.
Flexible Interface
Port
The IVS
2
uses a Universal Port architecture that has the flexibility to accommodate
station terminals, trunks, and adjunct processors. This universal digital back plane
allows the NEAX2000 IVS
2
to maximize slot space utilization and lower expansion
costs.
