Abstract

An apparatus, system, and method are presented for permitting a user to select whether the user's subscriber line will transmit in either the data or audio mode. A dual-mode apparatus is possible because of a select of which either connects the subscriber line to audio facilities or data facilities. The subscriber line belonging to the recipient is automatically connected to the data or audio facilities, based on the mode selected by the user.
