ABSTRACT:
A cordless telephone outlet device that not only provides the cordless telephone access to a telephone network, but also provides the cordless telephone the proper DC electrical energy for proper operation eliminating the need for an unsightly external DC power supply typically connected to an AC outlet. Further, the device significantly reduces exposure of the telephone line connection between the cordless telephone and the telephone network. The outlet device comprises a body having a communications connector mounted thereon and a base attached to the body. The base contains DC power supply circuitry that is connected to a source of AC electrical energy. The output of the power supply circuit is connected to a DC line terminated with a DC male plug. The cordless telephone can be directly mounted onto the device allowing the communications connector of the cordless telephone to engage directly with a corresponding communications connector mounted onto the device of the present invention while the device also provides DC power to the cordless telephone via the DC male plug. Alternatively, a relatively short telephone line cable can be used to electrically connect the respective communications connectors with the cordless phone mounted onto the outlet device of the present invention.
