  • In this thesis, the architecture and design of IWS(Inter Working System) which interconnects two different networks (PSDN: Packet Switched Data Network, PSTN:Public Switched Telephone Network) are described. IWS provides interconnection services for the compatibility of communication between two networks. IWS consists of network interface protocols, protocol conversion facilities and management facilities.

  • This paper describes the design and implementation of LAPD protocol for ISDN Basic Access. In protocol design, Software module is divided according to function and interfaces between modules arc defined. After that, Software structure is defined. LAPD protocol is designed by state machine design technique and implemented by SDL.
