Software
AUDIX software allows the DEFINITY AUDIX system to communicate 
with the switch through a telephone-like interface. This type of operation 
is called set-type emulation. The commands that subscribers and the 
switch use to access the system’s software correspond to the interface 
on a digital telephone, or set. 
The digital set the system emulates depends on whether the system is 
operating in native or non-native mode. In switch releases earlier than 
7.1, the DEFINITY AUDIX system emulates a 7405D digital telephone. In 
switch releases 7.1 and later, the system communicates with the switch 
using an ADX16D set-type interface, through which the switch can 
recognize the system’s AUDIX software.

Networking
Because of its telephone-like interface, the system can send and receive 
messages from other voice messaging systems as a telephone can. 
AUDIX software helps the system to communicate efficiently with other 
AUDIX systems.
The DEFINITY AUDIX system has two networking options that use these 
capabilities for message exchange:
■ AMIS Analog Networking
■ Digital Networking
AMIS Analog Networking
AMIS is a standard protocol among voice messaging systems. AMIS 
Analog Networking uses the Message Delivery feature to send 
messages to subscribers on other voice messaging systems that use 
the AMIS protocol.
AMIS Analog Networking sends a message through the system’s voice 
ports much like a telephone call. The recipient’s voice mail system 
receives the message as it would receive any other voice message and 
stores it in the recipient’s voice mailbox. Other voice messaging systems 
can send messages to the DEFINITY AUDIX system in the same way.
Digital Networking
Digital Networking is an efficient way for DEFINITY AUDIX, AUDIX R1, 
I
NTUITY, and Interchange systems to communicate with each other 
without using the systems’ voice ports. The DEFINITY AUDIX system has 
one Digital Networking port that can be dedicated solely to Digital 
1. For more information about digital station emulations, see
