Export one first data conveying capacity count value according to this first digital data processor through the data unit quantity that this local area network (LAN) frequency range limit distributor is sent to this external world's network; And when reaching one first transmission threshold value in a Preset Time, this first data conveying capacity count value just sends an inhibit signal to this first digital data processor, make this first digital data processor before next Preset Time begins, stop to transmit data to this local area network (LAN) frequency range limit distributor.
20., wherein more comprise the following step as 19 described frequency range limit distribution methods of claim the:
Export one second data conveying capacity count value according to one second digital data processor through the data unit quantity that this local area network (LAN) frequency range limit distributor is sent to this external world's network; And when reaching one second transmission threshold value in a Preset Time, this second data conveying capacity count value just sends an inhibit signal to this second digital data processor, make this first digital data processor before next Preset Time begins, stop to transmit data to this local area network (LAN) frequency range limit distributor.
