REDUNDANT SYSTEM TRANSMISSION LINE OPERATING SYSTEM AND REDUNDANT SYSTEM TRANSMISSION LINE OPERATING METHOD

摘要

PURPOSE: To obtain the redundant system transmission line operating method in which power consumption in an optical interface panel of a standby system is reduced. ;CONSTITUTION: A usual clock signal or a power supply is given to an interface panel 100a of an active system. Power is always supplied to a transmission line signal processing section 110b processing a signal from a transmission line 20 in interface panels 100b of the standby system for each prescribed period and a clock or a power supply is not given to a standby transmission line 120b other than the transmission line signal processing section 110b.;COPYRIGHT: (C)1995,JPO
