PURPOSE:To prevent detour crosstalk in a repeating device and reduce coupling loss by repeating an up data signal through gates which synchronize with clocks and also repeating down signal through gates which synchronize with the inverted clocks of said clocks. CONSTITUTION:The up data signal generated by the data transmission part 2-1 of a terminal station 1'-1 is received by a reception part 3-2 through gates G, G3 and G5, and G7 of the station 1'-1, a two-way repeating device 5'-1, and a terminal station 1'-2 which synchronize with clocks of mutual synchronizing clock generators 8-1, 8-2, and 8-3. The down data signal is received by a reception part 2-2 through gates G8, G6 and G4, and G2 which synchronize with inverted clocks of said clocks. Therefore, either of the up and down data signals detours to the opposite-directional data signal path and there is no transmission loss originating from a hybrid. |
