Abstract: An incoming call from a public communication network is sensed in a communication apparatus that is capable of switching between an automatic response mode and a manual response mode as a response to an incoming call. If incoming of a specific call signal has been sensed, the response to this incoming call is switched from the automatic response mode to the manual response mode.
Abstract: A line multiplier is formed of n upstream lines and m downstream lines where m>n by providing a micro-technology array of m×n crosspoints switches using, e.g., magnetic latching, wherein the latching magnets are heated to the Curie temperature to cause the state of a switch to change.
Abstract: The component essentially comprises two correlators (TR1, F1), (TR2, F2) shifted by one period or cycle from the information element. This component fulfils both the correlation and delay functions. The component also comprises a transmission channel with a filter identical to the correlator of the reception channel.Application to radiocommunications.
