Apparatus for transmitting analog voice and data communications on a phone line utilizing a telephone, a data terminal and a modem, the modem being connected to the data terminal. The apparatus comprises a mode switch for connection to the phone line, to the modem and to the telephone, the mode switch having at least first and second positions. When in the first position, the phone line is connected to the modem and when in the second position the phone line is connected to the telephone. A controller is connected to the mode switch for placing the mode switch in the first position or in the second position. A data transition tone generator is connected to the controller and to the phone line, and an actuator is provided for actuating the tone generator to produce a tone signal on the phone line at substantially the time that the contoller changes the position of the mode switch. Apparatus may further include a record/playback unit connected to the telephone lead and controller such that the controller may direct it to answer a call, playback a message, record when the phone is connected to the phone line, and stop recording when the telephone is not connected to the phone line.
