This section discusses the hardware and software components that make
up the IA 770 INTUITY AUDIX Messaging Application. Topics include:
See IA 770 INTUITY AUDIX Architecture for
an illustration of the hardware and software components that comprise
the IA 770 INTUITY AUDIX system.
Media Server Coresidency
The IA 770 INTUITY AUDIX Messaging Application runs on
a G700 Media Gateway controlled by a
Media Server. IA 770 is also available for Media Servers
controlling a G350 Media Gateway or G250 Media Gateway.
Media Gateways
A media gateway is a rack-mountable IP telephony chassis that allows Voice
over IP network processing and configuration of analog, IP, DCP, and
T1/E1 telephony connections. It controls data processing through the IP
Modules, and the media gateway processor, which controls
the Ethernet ports, USB ports, telephony media modules, and some basic
call processing functions.
You administer the media gateway resources by using either the Cajun command
line interface or the media gateway command line interface. The Cajun
and media gateway processors each have their own IP address for administration
access.
Media Server
The Media Server is an internal communication controller that
is inserted into the media gateway. The media server comes loaded with the following
resources:
- Red Hat Enterprise Linux Version 4 operating system
- Web server software
- TFTP server software
- H.248 and H.323 protocol IP software
- Avaya Communication Manager
software, which serves as the primary voice/data communications
application
When inserted into a media gateway, the media server serves
as a full-featured integrated data and phone communication system. The
media server has its own IP address for administration access.
Resources Shared by the INTUITY AUDIX System
The INTUITY AUDIX system uses
many of the media gateway and media server resources for call processing,
data storage, and access and use of administrative tools.
Specifically, the INTUITY AUDIX systems use the following resources:
- The Media Server hard drive for data storage and retrieval
- The Media Server TFTP server for:
- License file downloads and updates
- Backup and restore of data
- Software updates and upgrades
- The IP address of the Media Server for remote administration access and
TCP/IP networking functions such as Digital Networking and Message Manager.
- The Media Server license file for feature activation
- The Media Server General Alarm Manager for alarm display
As a result, the administrator administers some functions
of the INTUITY AUDIX system by directly administering the Intuity AUDIX
application, while the administrator administers other functions of
the INTUITY AUDIX system by administering the Media Server platform.
IA 770 INTUITY AUDIX
Software
The INTUITY AUDIX system software is loaded directly onto the Media Server
hard drive. The software provides message recording,
storage, and retrieval functions.
INTUITY AUDIX also provides the following features:
- The subscriber telephone user interface (TUI) software
- The AUDIX administration command line interface
- INTUITY AUDIX Platform software, which enables the INTUITY AUDIX
system to use lower level functions and includes the following capabilities:
- Switch integration software
This software allows call control messages (timestamps, calling
party information, called party information, and message waiting
indicator control) to pass between the INTUITY AUDIX system and
the Media Server Communication Manager software.
- Virtual port software
This software manages the voice message processing and emulates
physical analog ports for sending and receiving voice messages.
- Event and alarm logging software
This software logs alarms and sends them to the Media Server
Global Alarm Manager.
- Disk space management
This software manages the portion of the Media Server hard drive that is
allocated to the INTUITY AUDIX system.
Digital networking
IA 770 INTUITY AUDIX Hardware
H.323 protocol
Starting with Release 2.0 of IA 770 INTUITY AUDIX, new installations
make use of the H.323 protocol for all processes and communications.
Disk Partitioning
The disk partitioning scheme was modified starting with IA 770 Release 3.1 to simplify setup and configuration. Instead of seven partitions (four active and three duplicates) dedicated to messaging, there are only three partitions (two active and one duplicate).
The new layout of active partitions to be used by the Media Server products is defined as follows:
- /msg/software: for Intuity software, database, and add-on applications. Symbolic links, references to mount points, and so on are modified as needed to preserve the existing directory structure. The size of this partition is at least as large as the sum of the replaced three partitions on the latest media server product.
- /msg/media1: for the message bodies. The size of this partition is at least as large as the existing partition on the latest media server product.
Note:
This assumes the partition size is already adjusted to account for the move from the denser CELP voice encoding to the G711 voice encoding.
Media Modules
Media modules are boards with specialized functions that can be plugged
into the media gateway as needed.
Other modules currently available with the Media Server can be
installed to handle INTUITY AUDIX call traffic, but none of these is
specifically required for INTUITY AUDIX:
- MM710 T1/E1 media module
- MM712 DCP media module
- MM716 analog media module
- MM717 DCP media module
- MM760 Voice over IP media module
Ports
The S8300 Media Server and S8400 Media Server have one serial port. This serial port can be used for a direct connection
to a laptop or PC. The port is called Services on the S8300 Media Server and Service on the S8400 Media server.
For the AUDIX Data
Acquisition Package (ADAP) to work with the INTUITY AUDIX system, one
USB port must have an external Hayes-compatible modem attached.
Uninterruptible Power Supply
A separately purchased Avaya Backup Power Supply is available
to provide uninterrupted power to the media gateway and media
server. This uninterrupted power also applies to the INTUITY AUDIX system.
Terminals
You can administer the system through the use of a telnet session and
one of the following terminal emulations:
- Avaya 386
- Avaya 4410 (for PROCOMM PLUS 4410 or Terranova emulation)
- Avaya 513 (for Terranova emulation)
- Avaya 715
- Avaya 4425
- vt100
IA 770 INTUITY AUDIX Capacities
The INTUITY AUDIX system supports call traffic
that is generated by a maximum of 300 local and 60,000 to 70,000 remote
messaging subscribers. It supports up to 8 voice channels and
up to 8 networking channels.
The system supports approximately 100 hours of message
storage for all users, collectively. The system supports
up to 100 INTUITY Message Manager clients with a maximum of 32 simultaneous
sessions. Text-to-speech sessions are limited to four.
