A microphone boom is provided with extendable microphone arrays, and a headset having such a microphone boom. Based on measuring results, the nominal path corresponding to a penetration line of the structural components to be joined is calculated. A first slot in at least one frame transports in the service traffic portion asynchronous traffic and routing information for the asynchronous traffic in the telecommunications node. In a further exemplary embodiment, the inductor includes a voltage controlled oscillator, and the electrical element is electrically connected to the inductor and includes at least one of a varactor and a MOSFET.
