发明名称 Cordless phone and cordless phone system using such cordless phone
摘要 A cordless phone includes a base station coupled to a local line and a personal station communicating with the base station by radio. The base station includes a first channel unit for operatively coupling the personal station to the line so that communication between the personal station and an external station connected to the local line is carried out via the local line and the base station. A second channel unit is provided in the phone for operatively coupling the personal station to a digital highway through which digital data is transmitted so that extension communication between the personal station and an internal station, such as electric equipment, connected to the digital highway, is carried out via the digital highway and the base station. The cordless phone further has a switching circuit for selectively activating either one of the first or second channel units, based on control information supplied from the local line, the personal station or the digital highway.
