System Architecture

A specialized, modular architecture of hardware and software allows applications on the system to remain largely independent yet share computer resources and exchange data. The system architecture illustrates the hierarchy of system components used to build the Intuity AUDIX system. See the Intuity AUDIX System Architecture.

Topics include:

• Platform Layers
• Layer Interaction
• Processing Layer
• Service Layer
• Applications Layer

Platform Layers

The Intuity AUDIX platform consists of three layers that work together:

• Basic Processing Layer

This layer contains resources such as:

• Hardware components such as the chassis, the Pentium CPU, and disk drives
• UnixWare operating system (OS)
• SCSI terminator and interface
• Service Layer

Three software server modules–networking, message processing, and switch interface–plus administration and maintenance make up this layer.

• Applications Layer

Multiple software applications are available. A few examples are listed below. A customer can select any or all of the following:

• Voice Messaging
• FAX Messaging
• Text-to-Speech
• Text-to-Fax
• Internet Messaging
• TCP/IP Networking
• Enhanced List Application (ELA)
• Message Manager
• Avaya Voice Director
• Call Accounting Software (CAS)
• Switch Integrations
• Intuity Lodging
• support for www.messenger
• Aria user interface

Layer Interaction

The elements of the system's two base layers, processing and service, are accessible to any of the applications. Placing common elements, such as switch integration and digital networking outside the applications and into the platform, allows them to be used by all current and future software applications. This increases application operating efficiency, optimizes computer resources, and establishes uniformity across applications.

Processing Layer

The processing layer contains utilities and tools that the two layers above it can use. These utilities include alarming, backup and restore utilities, logs, and the operation, administration, and maintenance interface.

The processing platform layer includes the Intuity AUDIX system's base hardware and software components, as follows:

• Multi-Application Platform (MAP) chassis
• CPU
• Random access memory (RAM)
• Disk drives
• Removable media (diskettes and tape or disk cartridge)
• UnixWare operating system

Service Layer

The service layer is similar to the processing platform in that it provides tools and utilities for the software applications, although it is more specific in its offerings. The ability to record speech and play it back, create fax and email messages, transfer messages through a digital network, and communicate with Avaya and non-Avaya switches are just a few of the items in this layer that the applications can use.

The service layer includes hardware and software components integral to the tools offered, including the:

• Voice card for processing speech
• Speech and signal processing (SSP) circuit card for support of various speech technologies
• LAN circuit card for connecting to a local area network
• DCIU circuit card for communicating with Data Communications Interface Unit (DCIU) switches
• Multi-port serial circuit card for connecting to modems, terminals, or switch integration devices
• VB-PC card for communicating with switches not maintained by Avaya
• System administration software for elements that span the platform, such as voice port administration

Applications Layer

The applications layer contains independent programs that meet a particular business need. These software applications, such as Voice Messaging, Internet Messaging, and FAX Messaging, rely heavily on the foundation established by the first two layers.
