Abstract
PURPOSE:To enable data transmission between data way systems in loop, by forming two loop data way systems connecting data stations with different loop lines. CONSTITUTION:When data are transmitted from a data station 102 to a data station 108, the data station 102 gives a data way extension request signal to a data transmission 1 reception circuit 401 via a loop line 201. ON the other hand, when the circuit 401 receives the data way extension request signal, a control circuit 409 supplies a data way extension instruction to switching circuits 407, 408. Thus, the switching circuits 407, 408 switch lines, the circuit 407 supplies the data supplied from a phase compensation circuit 406 to a loop line 201 and the circuit 408 supplies the data from a phase compensation circuit 405 to a loop line 202. As a result, the data way is extended and the loop lines 201, 202 constitute a single loop line.
