Upgrades to R3.2
7-2 Issue 1 September 1995
Analog and Digital Port Emulations
To work with the switch, the DEFINITY AUDIX 3.2 system can emulate these port
boards:
■ TN746 analog port emulation, which allows up to 16 voice ports.
■ TN754 digital port emulation, which allows up to 8 voice ports.
■ TN2181 digital port emulation, which allows up to 16 voice ports. (Not
available with System 75, G1, and G3V1 switches.)
Earlier releases of the DEFINITY AUDIX system emulated only the TN746 analog
port board and the TN754 digital port board.
Digital port emulation is required to support digital networking.
Control Link and Display Set Integrations
The methods of switch integration and voice port emulation are not as tightly
linked as they were with earlier versions the DEFINITY AUDIX system.
NOTE:
“Display set” refers to the fact that DEFINITY AUDIX digital ports on the
switch are administered as if the display phone sets are connected.
Control Link
Integration
As with earlier releases of the DEFINITY AUDIX system,
the DEFINITY AUDIX 3.2 system lets you administer a
DCIU control link. The control link is required for a
DEFINITY AUDIX analog port emulation.
However, unlike earlier releases of the system, the
DEFINITY AUDIX 3.2 system offers control link
integration with digital port emulation. And though a
control link is not required for a digital port emulation,
you may need to administer a control link with digital
port emulation to support DCS, enhanced call transfer,
and leave word calling in AUDIX.
Display Set
Integration
Digital emulation without a control link is called Display
Set (DS) integration. DS integrations use the channels of
the digital voice ports to exchange information such as
call header data and control data. In earlier releases of
the DEFINITY AUDIX system, this integration was
referred to as “DP mode.”
