An exchange comprises a plurality of distributed nodes for processing calls from or to a first neighboring exchange, two or more of said nodes being arranged to be connected to the first neighboring exchange by separate trunk routes, and a signalling point code being assigned to the node-end of each trunk route, wherein the signalling point codes assigned to the node-ends of the separate trunk routes to the first neighboring exchange, differ from each other. The first neighboring exchange sees the exchange as if it were two or more conventional exchanges. The total amount of call processing for handling a call in a network which incorporates one or more exchanges of the invention can be reduced.
