Abstract
In a cordless telephone system, a radio communication unit is detachably connected to a base unit of the cordless telephone system. While the radio communication unit is electrically and physically separated from the telephone base unit, and brought out from a home or a firm, a radio communication is established between the radio communication unit and a telephone mobile unit, but also between the telephone mobile unit and a telephone subscriber via the base unit. Thus, an outdoor type telephone mobile unit is available in the cordless telephone system.
