Switching control device for transmitting cellular phone calls to fixed-network telephone |
摘要 |
A switching control device for transmitting calls received by a cellular phone to a fixed-network telephone enables people to receive calls transmitted to a cellular phone by way of a fixed network telephone particularly equipped with a plurality of extension lines via conversion operations. It operates with a cellular phone/fixed network telephone switching device in cooperation with an on/off device. When a cellular phone receives an incoming call, the switching device will first detect the main telephone set and its extension lines of their individual status of use; and the on/off device is selectively actuated of its on and off states and also its vibration ring operation according to the detection. Thereby a user can pick up a nearest extension line without rushing back to a main telephone set when an incoming call is transmitted to a cellular phone.
