Two-way moblle radlos today use mtcroprocessors to control radio functions. As shown in Figure 1 the control unit is often separated from the radio unit. Both units contain microprocessors. A scheme is needed to allow information to pass in both directions with the fewest possible wires and be compatible with existing push-to-talk schemes.
