Abstract

PURPOSE:To enable to perform the folding of high speed MODEM installed at a remote location with remote control, by the recognition of the pattern of the opposing multiplex distribution unit outgoing the folded specific pattern and by the folding instruction with the high speed MODEM. CONSTITUTION:The folding of the high speed MODEM 4 in contact with the opposing multiplex signal-distribution unit 5 produces the folded specific pattern of MODEM from the multiplex distribution unit 1 at this side, and the unit 5 receiving the pattern recognizes the pattern and makes the folding instruction to the high speed MODEM. Further, the release of folding is made that the RS signal is turned off with the unit 1, the interruption of the carrier is detected with the unit 5, and the release instruction of folding is made to the high speed MODEM. Thus, by using the units 1 and 5, the folding of the high speed MODEM installed at a remote location is made by remote control.
