A system including a modem locally generates a web page based graphical User interface for display to a user on a PC using different standardized browser applications and enabling a User to control or configure system functions. A processing system supports Internet compatible bi-directional communication and employs a method for providing local access to processing system parameters. The method involves receiving a locally initiated User command requesting access to a web page and validating authorization of the User command. The method also involves generating an Internet compatible web page for display containing a system parameter associated with the bi-directional communication in response to the validated User command. The generated web page is locally accessible via a web browser resident in the processing system and supports interactive functions such as, (a) configuring the processing system, (b) requesting display of system parameters, (c) selecting a service billing option, and (d) assigning Internet addresses.
