Abstract: This paper describes local area network (LAN) access using public wide area data networks and problems that arise when using integrated services digital network (ISDN) technology [Stallings 90] [Thachenkary 93]. To date mainly modem connections at serial lines with a terminal port have been the standard remote access technique. With ISDN it is foreseen that these modem lines will be replaced rather soon. This is mainly due to the fact that ISDN offers a more adequate bandwidth and is much more consistent from the point of view of access and embedding. This paper demonstrates in the main section a router-based solution for enhanced call management. One of the main advantages is the separation of the strategic module which defines the behavior and thus allows for a number of active connections exceeding the number of ports. It also addresses traffic and access control in the network environment.
