Abstract

PURPOSE:To make efficient the data transmission at the data way less in the channel number, by designating channel flag with the interface, in designating the channel in a small frame. CONSTITUTION:When data with channel flags F1-F3 corresponding to the channels CH1-CH3 enter the relay device 2 through the transmission line 1 of the data way, they are amplified and transferred to an interface 4. The interface 4 transmits the data CH1 to the channel 1 with the channel flag F1 in the small frame, the data CH2 to the channel 2 with the channel flag F2, and the data CH3 to the channel 3 with the channel flag F3 with split.
