Abstract

PURPOSE:To accommodate plural communication function modules to one digital subscriber line by detecting the state of contention control line so as to decide the use right of control information channel. CONSTITUTION:In sending control information from a 1st communication module 5 to an exchange, a data link control section 5 detects the 0/1 state of a contention control line 15. When the data link control section 5 confirms the idle control information line 14, the busy display is outputted to the contention control line 15 and the absence of the use request of an other data link control section 8 is confirmed again after a time T1 specific to the data link control section 5 to send the control information added with the control information channel 14- its own address. In detecting the busy state, the system is awaited till the contention control line 15 is idle and after the line is idle, the control information is sent by said procedure.
