<p>There is disclosed a network node, and a method of operation thereof, for use in, for example, an ISDN network. The node receives messages which include mandatory elements (without which the message cannot be processed), and optional elements (without which the message may still be processed). The mandatory elements are decoded and checked for errors and, only if they are present and error-free are the optional elements decoded and checked for errors.</p> |
