Telephone Interface
Telephone Interfaces provide connection and control via standard analog telephone lines, and are available
in pairs only as part of AudiaFLEX hardware. A Telephone Interface may consist of as many as five
separate blocks, as determined during placement into the Layout via the Object Toolbar. Two primary
blocks represent the audio Receive and Transmit functions. Three other control blocks may be added
individually at any time, representing functions for Dialer, DTMF Decode, and Control/Status.
The Receive block provides an output mix of incoming audio and internal ring tone
signals. Also, a Hook Switch (HS) control input node allows manual answering of
incoming calls, and a Ring Indication (RI) control output node provides indication of
incoming calls.
Double-clicking the Receive block produces a control
dialog box.
Auto Answer selects the number of rings (or OFF) for
automatic answering of incoming calls. Input provides
level adjustment and muting of incoming audio signals.
Ring provides level adjustment of the internal ring tone
signals for incoming calls. Noise Suppression enables
cancellation of telephone line noise.
