First Claim
Patent Images
1. An exchange controlling system for managing terminal groups, comprising:
- a plurality of terminals each being assigned an individual terminal number, said plurality of terminals being changeably arranged in groups, formed as switch service groups, each group being assigned a group number corresponding to a switch service;
a network for connecting a call from a subscriber to a destination terminal among the plurality of terminals; and
a central processor, operatively connected to the network, for controlling the network so as to connect the call from the subscriber to the destination terminal which is identified by a private subscriber number dialed by the subscriber and composed of at least one digit corresponding to the group number of a group that the destination terminal is arranged in and at least one digit corresponding to the destination terminal number and to perform the switch service corresponding to the group number.

Abstract
An exchanging and controlling system which manages terminal groups, has a plurality of terminals. Terminal numbers of the terminals used as a group are registered in the system. A group number corresponding to a switch service is assigned to each of a plurality of terminal groups used for an exchange service. A plurality of terminals of which each has an individual terminal number are registered to belong to each of the terminal groups. The number dialed by a subscriber includes at least one digit corresponding to its group number and at least one digit which corresponds to the terminal number of the destination terminal.

4. An exchange controlling system for managing terminal groups, comprising:
-
a plurality of terminals having terminal numbers and being changeably arranged in switch groups; a network for connecting a call from a subscriber to a terminal; a central processor operatively connected to the network for controlling the network; an individual memory for storing control data, by which the central processor controls the network, and a table having data of correspondences of switch services and switch groups which are permitted to receive the switch services; and a file memory having a first table for registering terminal numbers each assigned to a corresponding one of the plurality of terminals, a pointer for indicating a registered position for each of the terminal numbers registered in the first table, and a second table for indicating whether or not each of the terminals is registered to belong to the corresponding switch service group, wherein the central processor controls the network to connect a call for a switch service from a subscriber to a terminal which belongs to a switch service group corresponding to the switch service. - View Dependent Claims (5, 6, 7, 8, 9)
