Abstract

PURPOSE:To unnecessitate the preparation of a reserve line for each kind of a line interface by switching a reserve line corresponding means as the identical kind of the line interface with an in-use line corresponding means for fault detection at the time of the fault detection with the plural in-use line corresponding means for each kind. CONSTITUTION:When the fault occurs in either of communication lines 41 to 4n and in-use line corresponding parts 11 to 1n, a main control part 60 recognizes the interface by kinds of the fault line, selects the identical interface by kinds from among line interface parts 31 to 3m against a reserve line corresponding part 10, and indicates of switching by changeover switches 50a and 50b. When the selection and switching of the line interface parts 31 to 3m in the reserve line corresponding part 10 is finished, the control part 60 switches the in-use line corresponding parts 11 to in corresponding to the fault line to the reserve line corresponding part 10.
