Abstract
A method (300) and apparatus (200) provide for determining when a digital packet data signal and a voice signal are being concomitantly transmitted on a voice channel of a communication system. A sample of the transmitted signal (110) is compared (310) to a pre-transmitted sample of the digital packet data signal (108). In response to the comparison, a digital packet data transceiver hops (314-320) from the first voice channel to a different voice channel for transmitting the digital packet data signal when voice signals are present.
