Abstract

A method is provided for detecting and recovering from missed control words that signify a transition to or from a speech mode to a data mode in a communication channel. When in a speech mode, speech information is checked for errors. If an error is detected, the next frame or segment of information is assumed to be data information. The data information is examined for valid information such as a valid header. If a valid header is detected, data mode is assumed and if a valid header is not detected, speech mode is assumed.
