PURPOSE:To reply a dial call of a master station even when a control section of a slave station runs away by initializing a control section of the slave station by the master station when no reply comes from the slave station to the master station oven in excess of a prescribed time. CONSTITUTION:When a call signal from a master station is detected by a detection section 7, a signal corresponding thereto is outputted to a control section 6 and a consecutive time measuring circuit 8. In this case, if the control section 6 of the slave station 1 runs away, since no reply signal is sent via an interface 5, the call signal sending continues. It is measured by a consecutive time measuring circuit 8, which activates an initializing circuit 9 in excess of normal consecution time to initialize the control section 6. Thus, the control section 6 replies the call signal to connect the line with the master station. |
