Abstract
A voice/data switch (13) for selectively connecting an audio communication terminal device (15), such as a telephone, or a piece of electronic data communication equipment (17), such as a telephone facsimile device or a computer, to a Telco line (19) is disclosed. The voice/data switch (13) includes an announcement device and return signal detector (21) that is enabled to send a message to a calling station upon receipt of a ring signal. The message requests a return signal, which may be generated by the depression of a key of a DTMF key pad, for example, if connection to the audio communication terminal device is desired. If the requested return signal is not received, the Telco line (19) is connected by the voice/data switch (13) to the piece of electronic data communication equipment (17). If the requested return signal is received, the Telco line (19) is connected by the voice/data switch (13) to the audio communication terminal device (15).
