Claim:
1. An in-line coaxial cable apparatus for use in a cable-based network, the apparatus comprising: passive circuitry coupled in-line with the cable-based network, the passive circuitry being configured to receive an input signal from the cable-based network and to generate an output signal having frequency response characteristics controlled as a function of a value of at least one component in the passive circuitry; and active circuitry coupled with an input of the apparatus, the active circuitry being configured to generate a message signal in response to an interrogation signal supplied to the apparatus in a prescribed spectrum of the input signal, the message signal being combined with the output signal generated by the passive circuitry to form an output of the apparatus which is conveyed over the cable-based network, the message signal being indicative of a presence of the apparatus in the cable-based network.
