A wireless system that can switch the communication mode based on the type of a signal inputted into the system is provided. The wireless system comprises a subscriber terminal that is connected to devices which output audio signals or data signals and switches the signal path between an audio signal path and a data signal path based on the type of a signal inputted from the devices, and a base station that switches the signal path between an audio signal path and a data signal path based on the type of a signal inputted from a general public line network. The subscriber terminal and the base station are wirelessly connected.
