Abstract

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.
