Abstract
Abstract Recognition, including validation, of any dialed number may be fully accomplished entirely at an originating switching system (10) which includes a call-processing arrangement (200) that has stored definitions of the syntax (320, 350) and the grammar (400, 410) of one or more network numbering plans. The syntax definitions include definitions (312) of all individual symbol strings that are valid for the defined network numbering plans. The dialed number is parsed (340) to recognize therein all included symbol strings. Network facilities (16) for the call outside of the originating switching system are seized and used (344) only after all the included symbol strings are recognized and the entire dialed number is validated.
