Chapter 2 System Architecture
The NEAX ® 2000 IPS family consists of the NEAX 2000 IPS, NEAX IPS DM , and the NEAX
IPS DMR . These NEAX ® Internet Protocol Servers fuses existing NEC technologies with
dynamic advancements in hardware and software to satisfy the most stringent system
requirements. NEC's modular design, sensible migration, comprehensive network solutions,
and the ability to customize functionality to match specific business applications are just a few
of the NEC benchmarks that the new IVS builds upon.
NEAX ® 2000 IPS users have access to hundreds of service features that enhance productivity,
reduce operating costs, and improve communications efficiently. The innovative modular
hardware and software design allows efficient, effective growth within each module from its
minimum to its maximum configuration. This is achieved by a unique building block
architecture allowing growth without the loss of existing hardware or software.
Voice and Data Switching
The NEAX ® 2000 IPS systems support advanced applications such as Tandem Networking,
Centralized Attendant Service, Direct Digital Interface and other voice features. The system's non-
blocking architecture and distributed processor control hierarchy are designed to support the traffic and
control the load generated by voice and data switching. Station users may perform simultaneous voice
and data transmission at speeds up to 19.2Kbps over universal 1-pair wiring without the use of
modems. Proprietary Digital Instruments (D
term ) may be provided to increase system flexibility and
eliminate the need for conventional multiple line stations with their associated control equipment and
cable plant requirements.
Hardware Architecture
The NEAX ® 2000 IPS systems employ the latest advancements in Large Scale Integration
(LSI) circuits and component manufacturing techniques to create a highly reliable and
serviceable communications system. The IPS has changed from NEC's traditional PROM
based CPUs to a Flash ROM based for system software and RAM for data programming. The
NEAX
® 2000 IPS 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.
