ABSTRACT:
A method and system for initializing ISDN terminals include selecting a set of call service features and formulating a keymap, the keymap constituting a correlation between the selected service features and feature keys associated with the terminal. The keymap is entered into a memory of the terminal and is uploaded from the terminal to a central office without the necessity of a database administrator entering the keymap data into a central office database. Communication between the terminal and the central office can be facilitated by a universal SPID. After the keymap is uploaded, the central office downloads a SPID unique to the terminal for use in future calls made from the terminal. After the initialization of the terminal is complete, the selection of ISDN service features and the keymap may be revised by entering updated keymap data into the terminal memory and uploading the updated data from the terminal to the central office. Additionally, the terminal may be moved from the ISDN line on which it was first initialized to a second ISDN remote from the first line. The terminal may then be initialized by simply uploading the service and keymap data stored in the terminal memory to the central office or, if the data has been revised, by uploading the updated service and keymap data to the central office.
