Abstract
An interface box links a user's cellular telephone with all the standard telephone extensions at the user's home or office. In this way, the portable cellular telephone is the interface between the user's telephone extensions and the telephone company. The interface box connects to the cellular telephone's access connector, for example, whenever the cellular telephone is laid in a cradle of the interface box. Through this connector is sent all power, signal and input/output connections. In addition to the interface circuitry, the interface box preferably recharges the cellular telephone's battery.
