Supported Integration Methods

The Intuity AUDIX system supports the following integration methods:

• Inband Signaling
• Serial Interface
• Digital Communications Interface Unit (DCIU) Interface
• Digital Station Interface Circuit Card Interface
• LAN Interface

Inband Signaling

Inband integration is possible on supported switches through the use of dual-tone multifrequency (DTMF) signaling. Strings of DTMF tones are transmitted on the analog voice channel after the channel connects to answer the call, but before the voice is cut through. Typically, the string contains the calling party identification (CLI), the called party identification (CP), and the reason for the call (redirection or direct call).

See Configuration for Inband Switch Integration.

Serial Interface

Serial integration can be of two types:

• Proprietary

Serial integration requires an RS-232 interface. The elements of the serial protocol are typically a superset of those in the inband signaling, with the addition of a field describing channel information. When the call is forwarded to the system, a packet of information is sent through an RS-232 standard serial cable, providing the integration data for the channel the call arrives on.

• Simplified message desk interface (SMDI)

SMDI is an integration protocol that controls the exchange of integration information through a serial interface. It is an industry standard typically used by central office (CO) switches.

Some serial Centrex integrations require use of a modem or protocol translator placed in the RS-232 link.

See Configuration for Serial Switch Integrations.

Digital Communications Interface
Unit (DCIU) Interface

The DCIU integration is a proprietary data interface supported by DEFINITY switches. Intuity provides integration using the DCIU interface for DEFINITY switches.

See Configuration for DCIU Integrations.

Digital Station Interface Circuit Card Interface

The digital station interface circuit card provides digital station interface with a variety of switches. This card is designed to work as a digital voice and data interface card. However, in Intuity AUDIX systems, it is supported as a data interface only. The primary function of this circuit card is to provide call data for calls landing at the Intuity AUDIX voice ports. In these integrations, each tip/ring port on the system is connected to the switch through an analog line as an analog station. Each of the ports on the digital station interface card is connected to the switch as a digital station through a digital line.

See Configuration for Integrations with a Digital Station Interface Circuit Card.

LAN Interface

The LAN link allows the DEFINITY ECS and the Intuity AUDIX system to communicate over a private, dedicated LAN, or using a customer's LAN. The DEFINITY ECS is a server, and the Intuity system is a client that always initiates the communications session. This link uses a LAN circuit card installed in the Intuity AUDIX system and a C-LAN circuit pack (TN799) installed in the DEFINITY ECS. The two systems use TP/IP and a specialized DEFINITY protocol to communicate. The LAN link provides the same functionality as a DCIU link.
