Abstract
PURPOSE: To make easy replacement, by performing junctor replacement to the space division switch for spare system, and after replacement of exising system and spare system through the parallel running with existing system space division switch, by replacing junctor of existing system.
CONSTITUTION: The time sharing switch 3 is connected to the existing space division switch 1 and the spare system space division switch 2 via the selection switch 4. Further, the extension time sharing switch 5 and the selector switch 6 are placed respectively to the switches 1 and 2 so that the switch 2 can be used by the switch 6. After the junctor of the switch 2 is replaced with the network extension, the test for the junctor is made by using the switch 5. After the end of test, the selection and release of communication path for call from the switch 3 is made parallelly from the both of the switches 1 and 2. The switch 4 is selected and the switch 3 is operated by using the switch 2 finishing the replacement newly to perform the replacement of the junctor of the switch 1.
