Logging for an identified asset is coordinated when provided by applications implemented on multiple network elements. The layer incorporating the capacitor includes a ferromagnetic layer integrated with at least a portion of a surface of the capacitor, and in the circuit board or the layer incorporating the capacitor a coil is wound around the capacitor, or an inductor component is disposed in parallel with the capacitor. A second bus is adapted to couple audio data between the system and a microphone unit coupled to the system under control of the processor, and audio data are coupled to a TDM bus in the system operating under control of the processor.
