(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 Design
The NEAX ® 2000 IPS hardware is designed to provide the best of the following:
ƒ Flexibility
ƒ Capacity
ƒ Reliability
ƒ Optimum use of space
ƒ Minimal environmental requirements
ƒ Ease of installation and maintenance
A unique modular design is employed throughout the NEAX
® 2000 IPS. 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 NEAX
® 2000 IPS.
Fusion of RAM and ROM Programs
The NEAX ® 2000 IPS incorporates the flexibility of Random Access Memory (RAM) for Office Data
Memory and Flash ROM that contains the operating system. This fusion of divergent memory
technologies results in high performance 32-bit processing reliability in system operation as well as fast
recovery time in case of system power loss. This unique configuration provides improved efficiency for
updates to the generic program by floppy disk, and simplifies upgrades for system features and
capabilities throughout its life
.
Main Processor (MP) with Integrated Functionality
The NEAX ® 2000 IPS Main Processor (MP) is a heart of pure IP connections and TDM-based
connections. The MP employs a high-speed CPU, which is equivalent with Pentium. With this
processing power and System On Chip (SOC) technology, the MP integrates Device Registration
Server (DRS), AP01 (OAI) functions*, which are provided by an additional card in the previous IVS
2 .
Also, by means of today's advanced LSI technology, the MP card size is minimized and On-board
Ethernet Interface Card is mounted on MP without using an additional slot space in PIM. This interface
card is linked with LAN for call control processing of D
term IP and inter-work with MATWorX and OAI
server. (*RS-232C interface, Authorization Code service and FLF facility are deleted.)
Application Processors
The processing architecture of the NEAX ® 2000 IPS allows the system to be configured with
Application Processors that provide processing capacity for a specific application or multiple
applications. These EPROM-based processors support applications such as:
