A data switching system, having a switch processor, directs requests to initiate a new operation session of an executable application. In accordance with the present invention, the AAL2 signaling message includes a timescale value which represents a timescale over which at least one bit rate value characterizing the radio connection is defined. An out-of phase second pair of detection coils obtains a second differential inductive signal that is modified by a transition of the target within the inductive field.
