Abstract

Abstract A support device (AV) with a charging cradle (LS) for a mobile unit (MT) of a cordless or mobile telephone is extended with ancillary devices (ZE). The extensions normally installed as ancillary devices (ZE) are a designational call device, a hands-free device, a keypad, an answering machine, a visual ringing signal device and a signal amplifier. The ancillary devices (ZE) are coupled to the mobile unit (MT) via a transmission device, comprising a mobile coupling device (MKE) and a stationary coupling device (SKE). Speech and data are transmitted in both directions either via an infrared transceiving device, a radio transceiving device, an inductive transmission device or a mechanical contacting device. <IMAGE>
