Chapter 2 System Architecture

The UNIVERGE NEAX 2000 IPS family consists of the IPS, IPS DM, IPS DML and IPS DMR.

These UNIVERGE NEAX 2000 Internet Protocol Servers fuse 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 IPS builds upon.

UNIVERGE 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 UNIVERGE 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 (Dterm) 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 UNIVERGE 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

UNIVERGE 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.

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.
