The switch 10 is switched to the position of a customer to be processed by a digital switch 50 and the processor 12 inquires about a telephone number set as a part of a message 60 for its translation purpose of the database 14. As a result, the processor 12 obtains an index processed by the switch 50 having a processor 54 including a database 52. Then the switch 10 that is going to send an initial address message transmits again an initial address message having a new destination in response to a release message to identify a substitute switch.
