A system and method is provided whereby more data packets than are necessary may be transmitted in order to prompt a node of network to more quickly increase the number of packets that will be accepted by the node. The method also includes downloading information stored in the memory of the defibrillator to a base station having an external interface, and transmitting the information downloaded from the memory of the base station to an external location via the external interface of the base station. The resonance frequency of the equalizing resonator and the coupling with the rest of the filter are arranged so that attenuation increases at a point corresponding to an original attenuation minimum.
