Chapter 2 System Architecture

Hardware Design

The UNIVERGE NEAX 2000 IPS hardware is designed to provide the best of the following:

Flexibility

Capacity

Reliability

Optimum use of space

Minimal environmental requirements

Ease of installation and maintenance

A unique modular design is employed throughout the UNIVERGE NEAX 2000 IPS line of products. 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 UNIVERGE NEAX 2000 IPS.

Fusion of RAM and ROM Programs

The UNIVERGE 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 cycle.

Main Processor (MP) with Integrated Functionality

The UNIVERGE 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 IVS2. 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 DtermIP 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 UNIVERGE 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:

ACD Processor for call center applications SMDR for call accounting

Hotel Processor for Hospitality applications Message Center Interface (MCI)

Open Applications Interface (OAI), which connects to external computing devices to support a wide range of host computer-supported features.

These application processors provide the power and flexibility to meet specific users’ applications and traffic needs.
