Estimating the term…
An exchange is provided. Particularly, an office data management system where exchanges in a switching network can be operated and managed in common, a system for assigning personal numbers to subscribers, and a same subscriber's number migrating system where the same subscriber's number can be used even after a subscriber is sifted from an exchange to another are provided. Each node exchange includes a numbering plan inherent to a node, individual office data storing extension information, a numbering plan common to the entire network, and a common office data storing extension information. A certain exchange acting as a master in a station allots a copy of the common office data to each node via a data-link control circuit (FCCH) that transmits and receives call control signals and maintenance signals. A subscriber personal number assigning system that assigns a number to a person, not to a telephone set, by allocating a number to a logical index to the common office data, instead of a physical telephone set, is employed to the common office data. In the case of a subscriber's relocation, the same number can be migrated by arbitrarily changing a physical telephone set to a logical index existing in the common office data according to directions from a centralized maintenance terminal.
An office data management system comprising:
An office data management system comprising:
A subscriber's number assigning system in an office data management system, wherein subscriber's numbers allocated to subscribers in a network configured of plural exchanges are managed based on numbering plan information and subscriber information of common office data operated and managed in common in all exchanges so that said subscribers can be operated and managed as accommodated by one exchange;
A subscriber's number assigning system in an office data management system, wherein subscriber's numbers allocated to subscribers in a network configured of plural exchanges are managed based on numbering plan information and subscriber information of common office data operated and managed in common in all exchanges so that said subscribers can be operated and managed as accommodated by one exchange;
A same number migrating system in a subscriber's number assigning system, wherein in an exchange having said main storage memory by which a logical accommodation location, not a physical accommodation location, of a telephone set, is obtained as subscriber information when a dialed destination particularly indicates a subscriber including an extension or a B board by analyzing a selection signal dialed by a subscriber according to common numbering plan information in said common office data, said exchange has conversion information management means within a common memory which can be accessed from and changed by all the exchanges in said network, said conversion information management means associating a logical accommodation location with a physical accommodation location of a telephone set or a subscriber line;
A same number migrating system in a subscriber's number assigning system, wherein in an exchange having said main storage memory by which a logical accommodation location, not a physical accommodation location, of a telephone set, is obtained as a subscriber information when a dialed destination particularly indicates a subscriber including an extension on a B board by analyzing a selection signal dialed by a subscriber according to common numbering plan information in said common office data, said exchange has conversion information management means within a common memory which can be accessed from and changed by all the exchanges in said network, said conversion information management means associating a logical accommodation location with a physical accommodation location of a telephone set or a subscriber line;
