1. , a kind of telephone wire that is used in building is gone up the equipment (60) of configuration network to (62), described telephone wire is to transmitting analog telephone signal simultaneously in analog telephone frequency band (41), described network transmits the spread-spectrum digital data signal being independent of and being higher than in the numerical data frequency band (43) of analog telephone frequency band, described equipment comprises:

  • Can connect right first phone connector (36) of telephone wire;

    Be coupled to the high pass filter (32) of described first phone connector, be used for only by being positioned at the signal of numerical 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 conduction first digital data signal in the numerical data frequency band, to carry out two-way packet-based digital data communications;

    The data connector (33) that can connect data cell;

    WithBe coupling in the transceiver (12) between described data connector and the 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 first digital data signal be OFDM modulation or on/wireless signal of lower frequency conversion, or described modulator-demodulator comprises the part of radio modem (14,15) at least.
