DECENTRALIZED CONTROL EXCHANGE SYSTEM

摘要

PURPOSE:To attain the reduction of memory capacity needed for the interpretation information and also to give freely numbers to subscribers, by registering an interpretation table of subscribers stored in each subsystem to an individual memory and deciding the store position of a called subscriber based on the interpretation table. CONSTITUTION:Subsystems 1, 2 and 3 are provided. Then 881-1xxx and 881-2xxx are allocated to the system 1; 881-3xxx and 881-4xxx are allocated to the system 2; and 881-5xxx and 881-6xxx are allocated to the system 3 respectively in a standard relation. However this relation is not based on the fixed subscriber numbers and therefore even subscribers having the numbers other than those mentioned above can be stored to subsystems 1-3. Then the store position is informed to the subsystem at the transmission side by the inter-subsystem communication only to the incoming call of the subscriber having no standard relation. Thus a connection is possible between the calling and called subscribers.
