         [0004]    German Published Patent Application No. 198 35 433 describes a communication terminal or telephone, in particular for Internet telephony, which has a touch-sensitive display as input/output interface and means for displaying an HTML-like page on the display via which the functions of the terminal are able to be operated. The telephone includes a freely configurable operating surface. To this end, the telephone has a touch-sensitive display and an Internet browser to process so-called HTML pages. The display is used as input and output interface for a user. The Internet browser or www-browser may be called a conversion device or an interpreter of HTML pages. In addition to text, control characters that may lead to other pages or trigger functions are also representable on the HTML page. The browser function may run in the telephone on an already available processor or on an additional processor. In an analogous manner, the HTML page is able to be stored in the telephone. Via the HTML page, the operating surface of the telephone may be freely configured by any provider of telecommunication services. The browser represents this specific operating surface on the telephone. The HTML page may be supplemented by Java applets or corresponding technologies. The provider loads the HTML pages into the telephone or terminal via the Internet protocol, for instance. The terminal is usable, for example, only after the user surface has been imported by the operator of the provider.
