AUDIX Networking enables an organization to transmit messages between two or more AUDIX systems, making the group of systems appear as one large system. One-Cabinet AUDIX systems, Two-Cabinet AUDIX systems, and AUDIX Large systems can be used. These systems can be located on the same site or spread out over several locations in the same or different cities. A single network can have up to 101 systems (a local system can be connected to up to 100 remote systems).

When considering adding more than one system to a single switch, keep in mind that although several systems can be networked at a single location, the systems may or may not be able to be installed as fully integrated AUDIX systems (that is, with a data link installed between the AUDIX system and the switch). The number of directly connected AUDIX adjuncts depends on the switch:

∙System 75 and DEFINITY Communications System Generic 1, Generic 3i, and Generic 3s support one directly connected AUDIX system.

∙System 85 R2V2 and R2V3 support up to four AUDIX adjuncts.

∙System 85 R2V4 and DEFINITY Generic 2 and Generic 3r support up to eight AUDIX adjuncts.

Any additional AUDIX systems must be installed as stand-alone systems.

THE NETWORK INTERFACE

An AUDIX system provides three types of network connections, using either the Electronic Industries Association (EIA) RS-232 protocol or AT&T’s DCP. They are:

∙Dedicated RS-232:AUDIX systems communicate through direct cabling. No connection to the switch is required. Communication between AUDIX systems is straight RS-232. Any channel connected in this manner cannot be shared with other adjuncts or with other AUDIX system applications. This connection requires AUDIX R1V5 or later software and a TN539 or TN539B ACCE circuit pack.

∙Switched RS-232:AUDIX systems communicate through dial-up modems. Communication between systems is via analog facilities. Channels connected in this manner can be shared with other systems or with the AUDIX Call Detail Recording Package (CDR). This connection requires AUDIX R1V5 or later software and a TN539 or TN539B ACCE circuit pack.

Special Application: The RS-232 channels can be converted to DCP before entering the switch. This is done with a data module instead of the modem. This, too, is a dial-up connection; all six AUDIX network channels appear at the switch as DCP channels.
