Abstract: Signals are transmitted from and to a plurality of terminals. The apparatus has a plurality of signal connections and at least two antenna connections. One signal connection is a main connection or a secondary connection. At least one main connection for each terminal can be connected. The number of signal connections is greater than the number of antenna connections. At least one linking element allows each main connection to be electrically linked to each antenna connection. A device for detecting transmitting activity detects a transmitting main connection based on a signal property of a signal, wherein the signal is present on a signal link section which is linked to the main connection. Signaling links between the signal connections and the antenna connections can be established on the basis of the detected transmitting main connections and the number of signal connections assigned to a terminal.

Abstract: A method for detecting oscillation in a signal coupling device includes at least one oscillation detection step. The oscillation detection step includes the steps of determining an undamped signal level of a signal on a signal path of the signal coupling device in a first step, reducing a gain of the signal path in a second step, and determining a damped signal level of the signal on the signal path and a deviation between the undamped signal level and the damped signal level at least once in a third step. An oscillation is detected if at least one deviation determined in the third step of the at least one oscillation detection step is higher than or equal to a predetermined oscillation threshold value. A device for detecting oscillation in a signal coupling device and a signal coupling device are also provided.
