Abstract
An ATM switching node (20) which implements PNNI protocol has a table (known as the consolidated table) which stores plural records, each record associating a connection request input field with corresponding routing information. The node has table maintenance logic (78) which updates the table to consolidate therein both records initiated by operator input and records developed from PNNI updating information. The PNNI updating information is generated by a PNNI protocol unit (56) which consults a topology database of the node. Provision of the consolidate table obviates consultation of multiple tables.
