Product Information
The AXB-DTMF+ DTMF Interface (FIG. 1) links an Axcess central controller to a telephone network, enabling dual tone multi-frequency (DTMF) and audio pass-through control. The AXB- DTMF+, with a programmed central controller, processes incoming calls and initiates outgoing calls to any pager or cellular phone.
The multi-function AXB-DTMF+ can be integrated for many imaginative and creative purposes within a home or work environment using touch-tone control. For example, the AXB-DTMF+ can announce callers by caller ID data, or can set up an audible menu selection to process incoming calls for routing.
The audio pass-through can be used with an AXC-SPE Enhanced Speech Synthesizer card, or PC sound card to produce audible menus, monitor phone audio, or provide audio input such as music on hold. The AXB-DTMF+ allows a user to issue instructions to the AMX Central controller from a remote location using any touch-tone telephone.
The AXB-DTMF+ receives and decodes DTMF audio signaling and sends the decoded data to the central controller for the switching/controlling of any devices connected to the central controller. An Axcess program written on a personal computer, and downloaded to the central controller, enables the central controller to interpret the data received from the AXB-DTMF+. The program may also issue menu selections over the telephone through an optional AXC-SPE card. For more information about programming a central controller, refer to the Axcess Programming Guide.
