ABSTRACT:
A device for detecting a transmission of at least one of a first communication signal and a second communication signal in a communication network is disclosed. The first communication signal is transmitted within a first frequency band, and the second communication signal is transmitted within a second frequency band. The device includes a housing and a filter circuit in the housing. The filter circuit is adapted to communicatively interface with the communication network and includes a first circuit path for passing the first communication signal, wherein the first circuit path includes a first indicator for providing a first indication of the passed first communication signal. The filter circuit further includes a second circuit path for passing the second communication signal, wherein the second circuit path includes a second indicator for providing a second indication of the passed second communication signal.
