Publisher's Synopsis
SDL is the Specification and Description Language recommended by CCITT (Comite Consultatif International Telegraphique) for the unambiguous specification and description of the behaviour of telecommunication systems.;Besides serving as a textbook on SDL, this volume is an introduction to the area of protocol specification. By explaining SDL in a specific area of application, it is hoped that the reader will understand the practical value of the language.;SDL is described at three levels: a general overview; a more detailed description of the basic functions; and an investigation of the advanced functions.
