Abstract

A communications system that is arranged to transport so-called connection oriented messages via respective virtual circuit connections is enhanced so that it also transports so-called connectionless messages via a predefined virtual circuit connection that is common among those data modules which participate in the connectionless message service. In particular, each module which participates in the connectionless message service is assigned, in addition to a primary address that is used in conjunction with associated channels numbers to transport respective connection oriented messages, a common address and a channel number that is usedsolely for transporting connectionless messages. In this way, the communicationssystem processes connectionless messages as though they were connection orientedmessages.
