Abstract:
A process for narrow band data communication between at least one user (PSTN user, ISDN user) and at least one network server (NS) of a service provider, in which first the establishment of a switched connection between the user and an access point (AS) occurs and subsequently, during the connection, a data exchange session (session) occurs as a point-to-point connection between the user and the network server, with the establishment of the switched connection occurring between a user-oriented connection point and an access point for the desired network server, characterized in that multiple users are connected together into a local area network (LAN); and the data communication connection between a LAN/WAN adapter acting as a central connection point and the access point (AS) of the network server (NS) of the desired service provider occurs via a data protocol (L2TP) containing an address identification for the respective desired point-to-point (PPP) data connection, wherein the establishment of a data communication connection, consisting of the following steps:the user initiates the establishment of the connection; the user dials the number of the access server (access server); the switching network produces a PSTN/ISDN switched connection between the user and the access server (AS); the calculation of fees of the PSTN/ISDN switched connection begins; the user begins a data exchange session (session) with the access server, with the address (e.g. ATM, FR) of the service provider being contained in the data exchange protocol and the address being used to produce the desired connection between the access server and the network server of the desired service provider; a point-to-point data connection (PP) between the user and the desired network server (NS) is produced, with, in particular, the user authentication, the IP address assignment, and the encryption also occurring via the data exchange protocol; and the calculation of fees in regard to the session is begun.
