The OSI (Open System Interconnection) reference model is the basis of modern data network design, but it underlines the public switched telephone network (PSTN) as well. For voice engineers learning how to send services over data networks, and for Internet engineers learning how to tap into the PSTN, the OSI model is an ideal point of reference. This book covers roles, functions, definitions and the fundamentals that are required of entry-level personnel.
