Abstract
A method and apparatus for routing calls in a switched digital network and a processor for use in such a network are provided in which tables of call control information store information for different categories of call control information in separate parts of the table or in separate tables. The information in the tables is available for different network entities to share in routing calls. The separation of different categories of information simplifies the task of making changes to call control tables and can allow certain of the separate tables to be portable across the network.
