Method for concurrently establishing switch redirection for multiple lines of the public telephone network

摘要

Advanced Intelligent Network (AIN) platforms include data bases populated with information pertaining to all phone numbers within a communications network. A large number of telephone numbers may concurrently be prespecified in a data base by a subscriber, together with alternate telephone number destinations corresponding to different locations, for redirection. Redirection set up for all of the subscriber's lines is accomplished by a single data entry operation into the data base in accordance with a template or table of designations customized by the subscriber. Redirection information may be transmitted to the AIN data base via a telecommunication line and an adjunct processing device associated with the AIN data base, using a terminal interface or dialed digit inputs; or the redirection information may be entered by interaction with a network switching office which sends the information to the data base via the network's signalling channels. Such information may specifically identify a portion, if not all, of the subscriber's lines. Each specified line may be associated with one or more redirected destinations.
