  • Cordless telephone and clock management method
    Patent number: 6363256
    Abstract: A cordless telephone system includes a base station having a base clock indicative of the time of day, and a handset having a handset clock indicative of the time of day. The handset is synchronized to the base station. When power is lost in the handset or the base station, the unit with power detects loss of synchronization therebetween. Upon restoration of the power, the continually powered unit provides the power restored unit with clock recovery information for updating the clock of the power restored unit.
