1. for the telephone wire in building, (62) are gone up to the equipment (60) of transmission and receiving digital data for one kind, described telephone wire is to transmitting analog telephone signal in analog telephone frequency band (41) simultaneously, and independent of and higher than the digital data frequency band (43) of analog telephone frequency band in transmit spread-spectrum digital data signal, described equipment comprises:

  • The first phone connector (36) that telephone wire is right can be connected;

    Be coupled to the high pass filter (32) of described first phone connector, for by means of only the signal being arranged in digital data frequency band;

    Be coupled to the multi-carrier modem (17 of described high pass filter,

         37), described modulator-demodulator is configured to based on described telephone wire to the digital data signal conducting the first spread-spectrum in digital data frequency band, to perform two-way packet-based digital data communications;

    Can the data connector (33) of connection data unit;

    WithBe coupling in the transceiver (12) between described data connector and described modulator-demodulator, described transceiver is configured to carry out packet-based numerical data two-way communication with described data cell;

    It is characterized in that;

    Described modulator-demodulator (17,37) radio modem (14 is comprised,

         15) and up/down frequency changer (31), wherein said up/down frequency changer is configured to digital data signal be transformed to radio bands from digital data frequency band or transforms to digital data frequency band from radio bands.
