Abstract

PURPOSE:To prevent error, log information and constitution information, etc., on all service processors(SVP) from being disable in transfer even in the case of a one-place disconnection in a communication among the SVPs. CONSTITUTION:When a disconnection is caused at a point (a), information of slave SVPs 21-23 are transferred to a maintenance center 90 through a master SVP 20, a telephone exchange 50, and a telephone line 60 by looped transmission counterclockwise circulation 80a and information of slave SVPs 24 and 25 are similarly transferred to the maintenance center 90 through the master SVP 20, telephone exchange 50, and telephone line 60 by looped transmission clockwise circulation 80b. Therefore, a failure in information transfer due to the disconnection is prevented.

Operation: When the master SVP is one, the master SVP
Can switch the loop transmission counterclockwise and clockwise, and normally exchanges information with the slave SVP in the counterclockwise direction, but when there is one break, select either counterclockwise or clockwise. Therefore, the maintenance center and the SVP are not disconnected. In addition, by setting n master SVPs and connecting them with different telephone lines,
The slave SVP determines the priority order of the master SVP, and when the first master SVP is in a connection state with another slave SVP or in a disconnection state, the slave SVP is connected to the second master SVP, and the maintenance center and the SVP are connected. Never be disconnected.
