摘要:
A peripheral device cable, connected to a peripheral device, integrally incorporates a subscriber link that is a physical line for transmitting subscriber information in synchronization with a highway clock and a control link that is a physical line for transmitting control data in synchronization with the highway clock. A control data converter controls interfacing between the control data transferred over the control link synchronously with the highway clock and control data that a control unit transmits/receives asynchronously with the highway clock. The subscriber link is connected to a switch.

An electronic device is disclosed in which parameters or functions thereof can be executed with fewer key operations. An electronic device such as a facsimile device has a display unit that displays a plurality of keys that can be respectively used to specify and select the parameters or functions thereof, and will determine whether the length of time that each of the plurality of keys is pushed is long or short. If a key is pushed for a short period of time, that key will simply be selected, and if a key is pushed for a long period of time, that key will be selected and facsimile transmission will automatically begin.
