Abstract

External invocation of features on a switching system from a network is made possible by aliasing otherwise-unused network numbers that are assigned to the switching system within the network numbering plan to feature-access codes of the switching system's internal numbering plan, in the switching system's call processing arrangement that uses stored definitions of syntax and grammar of the internal and network numbering plans. The aliasing is accomplished as follows. The syntax definitions of the internal numbering plan include definitions of individual feature access codes, while the syntax definitions of the network numbering plan includedefinitions of the aliased network numbers, which either are the same as the definitions of the corresponding feature access codes or direct the aliased network numbers to be translated into the corresponding feature access codes. In use, symbol strings received by the switching systems are parsed to identify them as featureaccess codes or aliased network numbers, requisite translations are performed, and feature modules that are pointed to within the definitions are invoked.
