A junction station of a telephone network is constructed for connecting with a plurality of telephone terminals by a link multiplexed to provide a multiple of channels for downloading of digital contents from a data source to a plurality of telephone terminals. In the junction station, a detecting block detects when a plurality of telephone terminals issue connection requests within a predetermined time interval for downloading of the same digital contents. An allocating block is responsive to the detecting block for allocating one of the multiple of the channels of the multiplexed link commonly to the plurality of the telephone terminals to establish a downward connection to the plurality of the telephone terminals. A controlling block obtains the digital contents from the data source through the telephone network and distributes the obtained digital contents concurrently to the plurality of the telephone terminals by the commonly allocated channel. |
