<p>PURPOSE:To rapidly execute the dividing work of a fault occurrence position at the time of a fault occurrence and to efficiently execute periodical inspection and maintenance by providing each multi--media multiplexing device with plural speed converters. CONSTITUTION:This system is constituted of multi-medium multiplexing devices 1, 2 consisting of rapid data line terminal parts 11, 21, slow data line terminal parts 12, 22 for interfacing with the signal formats of slow data lines, multiplexing/separating parts 13, 23, rapid line terminal parts 14, 24 for interfacing with the signal formats of rapid digital-only lines, signal folding parts 15-1, 15-2, 25-1, 25-2, and speed converters 16-1, 16-2, 26-1, 26-2 for converting respective folding signals into prescribed communication speeds, communication terminals 3, 4 and a rapid digital-only machine 5. Consequently, the division of a fault generating position at the time of a faute occurrence can be efficiently executed and periodical inspection and maintenance can be rapidly executed.</p> |
