Abstract
A system includes a modem which receives a burst of a time division multiple access (TDMA) signal. A burst mode controller, connected to the modem, is operable to detect a unique word in the burst. If the unique word is not detected, the burst mode controller loads a predetermined bit pattern into a channel identifier field of the burst. The predetermined bit pattern indicates that a payload field of the burst contains voice data.
