Abstract
For external terminals, telephone number information is provided internally in a private branch exchange. Upon call setup, signalling information is checked to determine if telephone number information is internally present in the private branch exchange to a user of a B-channel in an ISDN system. As warranted, dialing of the telephone number is initiated by a system controller in the private branch exchange.
