Abstract
A method and system which detects failures in communication between a base unit and an extension unit in a wireless communication system and which resets the system upon detecting such failures is described. A wireless communication system in this invention can use an RF over the air communication channel or an AC power line communication channel. In this method and system failures in the extension unit are detected and the base unit is reset, thereby permitting further use of the telephone communication link. A variety of embodiments are disclosed, including: transmitting a low frequency signal from the extension unit; transmitting a high frequency signal from the extension unit; periodically transmitting a status command signal from the extension unit; and detecting the signal strength of the transmitted signal from the extension unit in the base unit.
