The Open System Interconnection as a building block in a health sciences information network

R W Boss
1985 Bulletin of the Medical Library Association  
The higher layers require special development for particular applications. This paper describes the OSI, its application in health sciences networks, and specific tasks that remain to be undertaken.  ...  The most appropriate standards appear to be those being developed under the Open System Interconnection (OSI) reference model, which specifies a set of rules and functions that computers must follow to  ...  The CCITT X.25 public data network interface, for example, spans the physical, link, and network layers. From a communications compatibility standpoint, the transport layer is the most critical.  ...

Introduction to intelligent networks [chapter]

J. Harju, T. Karttunen, O. Martikainen
1995 Intelligent Networks  
The development of telecommunications techniques and the need for more advanced services has created projects on standardization of international Intelligent Networks (IN).  ...  The standards of Intelligent Networks defme IN in an abstract point of view, so it leaves the service providers the decisions on their own implementations.  ...  IN is applicable to a wide variety of networks, including but not limited to: public switched telephone network (PSTN) mobile, packet switched public data network (PSPDN) and integrated services digital  ...

OSI Reference Model--The ISO Model of Architecture for Open Systems Interconnection

H. Zimmermann
1980 IRE Transactions on Communications Systems  
The OS1 Reference Model was also recognized by CCITT Rapporteur's Group on "Layered Model for Public Data Network Services."  ...  In July 1979 the specifications of this architecture, established by SC16, were passed under the name of "OS1 Reference Model" to Technical Committee 97 "Data Processing" along with recommendations to  ...  In this regard, acceptance of the OS1 Reference Model by CCITT Rapporteur's Group on Layered Architecture for Public Data Networks Services is most promising.  ...

This layer is the basis of the reference model and defines ISO reference model for describing interfaces.transmission line, or channel, for transporting the bit-stream from A to B in figure 1.  ...  Layer 3: network layer The network layer provides the choice of information paths in the network, for example the dialled lines of a data-exchange system. This layer was not used in the present case.  ...
