Abstract

PURPOSE: To improve the packaging efficiency through the common use of a power supply, etc., by decentralizing the shared memories of a duplex system to each system.
CONSTITUTION: A completely duplicated connection structure is secured between each element of an A system 10 and a B system 11 and common memories CM#A and CM#B. When both systems 10 and 11 are used with switching as a working system and a spare system, the memories CM#A and CM#B are also used with switching as a working system and a spare system. These memories CM#A and CM#B are packaged into the housings of both systems 10 and 11. In such a constitution, an exclusive power supply is not needed and therefore the packaging efficiency is improved with a common memory system.
