Switch Integration

Switch Integration

In most switches, the DEFINITY AUDIX system operates in a mode called display set integration. In display set integration, the DEFINITY AUDIX system communicates with subscribers’ telephones to perform such actions as lighting MWIs and recording callers’ names and extensions. The four main chapters of this book focus solely on display set integration.

The DEFINITY AUDIX system can, however, communicate with the switch in another mode, called control link integration. In control link integration mode, the DEFNITY AUDIX system connects to a Processor Interface (PI) or a Processor Gateway (PGATE) circuit pack in the switch.

When the DEFINITY AUDIX system integrates with the switch in control link mode, the system communicates directly with the switch, rather than subscribers’ telephones. The switch, for example, lights subscribers’ MWIs when they have AUDIX messages, and it can route calls away from a DEFINITY AUDIX port that is busy. Control link integration streamlines the DEFINITY AUDIX system’s interactions with the switch, so the system can operate faster and more efficiently.

DCS Networking

Control link integration allows the DEFINTY AUDIX system to operate seamlessly in a Distributed Communication System (DCS) network—a network of switches that are connected so they act as one switch. In control link mode, the DEFINTY AUDIX system can support subscribers on up to 20 remote switches (or nodes) in a DCS network as local subscribers.

Analog Port Emulation

In display set integration, the DEFINITY AUDIX system can emulate two digital station circuit packs: the TN754 8-port digital circuit pack or the TN2181 16-port digital circuit pack. In control link integration, the DEFINTY AUDIX system can also emulate a 16-port analog circuit pack, the TN746.

Analog port emulation increases system speed and may be less expensive to install for some customers. However, analog port emulation is not compatible with some features for digital port emulation, such as Digital Networking.
