Abstract

A cordless system comprises a laptop computer with a modem connected to a modem data port on a cordless telephone handset. A direct sequence spread spectrum RF link is established between the cordless telephone handset and a base station. Both the telephone network and a desktop computer with a modem are connected to the base station. When the cordless telephone handset detects that the laptop computer wants to go off-hook, a selection signal is also sent by the cordless telephone handset to the base station to indicate whether the call is to be directed to the telephone network or the desktop computer. When the base station detects that the desktop computer wants to go off-hook, a selection signal is also sent by the desktop computer to the base station to indicate whether the call is to be directed to the telephone network or over the RF link to the laptop computer. Incoming calls from the telephone network are directed to the desktop computer by the base station with a ring indication going to the cordless telephone handset. If the laptop computer answers the ringing, the cordless telephone handset indicates an off-hook condition to the base station and the base station routes the incoming call over the RF link to the cordless telephone handset and the laptop computer.
