PROBLEM TO BE SOLVED: To provide a line connector capable of obtaining a synchronization clock required for communication from either one of the high speed side and low speed side of the line connector and being applied to various uses. SOLUTION: This line connector is provided with an n:1 selector 80 connected to a line terminating device disposed to plural low speed side lines for selecting one of the low speed side lines, a clock interruption detection circuit 82 for judging whether or not a clock transmitted through the low speed side line selected by the n:1 selector 80 is interrupted, a PLL circuit 84 for generating the clock and a logic circuit for outputting the clock generated by the PLL circuit 84 to a network side and a terminal side as synchronizing signals in the case of judging that it is interrupted by the clock interruption detection circuit 82 and outputting the clock transmitted through the low speed side line selected by the n:1 selector 80 to the network side and the terminal side as the synchronizing signals in the case of judging that it is not interrupted. |
