发明名称 MULTI-BASE STATION CORDLESS TELEPHONE
摘要 The present invention is a system of at least one cordless telephone, a hom e base station and at least one non-home base station. A roaming cordless telephone out of range of its home base station will use a non-home base station to direct digital mode signals to its home base station. The home base station will convert the digital mode signals to analog signals and communicate them with the telepho ne network. Only a single direct line connection is needed for the home base station, as the digital mode signals and the analog signals communications do not interfere with each other. The user may potentially avoid long distance charges by using th e non--home base station as a conduit while using the home base station as the telephone network site for long distance charge accrual. Further, the necessity for using a cellular telephone with the consequent charges is avoided.
