SELF-SAVING RING NETWORK AND NODE RAISING SYSTEM

摘要

PURPOSE: To prevent a heavy data error by preventing the generation of the unnecessary switching of the selector of an adjacent node at the time of node raising. ;CONSTITUTION: When a power source is turned on, a control part 143 of a fourth node 14 performs setting for allowing an alarm indication signal(AIS) generating part 142 to generate an AIS, and allows the AIS generating part 142 to generate the AIS. Thus, a selector 111 of an adjacent first node 11 can be prevented from being switched.;COPYRIGHT: (C)1994,JPO
