Objective The objective of this project was to define the services to be provided by an integrated traffic LAN and to define a stable interface between terminals and a LAN access unit. This interface was to comprise the physical interface and the service access protocols by means of which such services could be used. The definition of service parameters, events, etc, was to be presented for standardisation to ECMA and IEEE. After having analysed several possible types of standard interfaces (parallel, serial, and computer-bus), the project focused its effort on the external, serial-link E-interface, which was seen as the most competitive and the most likely to become a standard. The objective of the project was to define the services to be provided by an integrated traffic local area network (LAN) and to define a stable interface between terminals and a LAN access unit. This interface was to comprise the physical interface and the service access protocols by means of which such services could be used.The project focussed its effort on the external, serial link E-interface, which was seen as the most competitive and the most likely to become a standard.The final specification of this interface was produced and validated, and was submitted to ECMA for consideration. A breadboard model, including customized integrated circuits has been implemented. On the basis of the established standard, it is possible to connect data terminal equipment of different types and manufacturer, independent of the structure and media used. The development of the potentially large LAN and terminal market depends heavily on the existence of such a recognized standard. The E-interface concept has apparently not been accepted by either the LAN or terminal manufacturers, because real time voice, audio and video communication does not take place via LANs. However, the E-interface concept was used as the basis for the Broadband User Network Interface (BUNI) for the Integrated Broadband Communication (IBC) network. The need for standardization appears to be higher in the area of public networks than in the LAN domain.The final specification of this interface was produced and validated, and was submitted to ECMA for consideration in January 1987.
