Abstract
A method for using alphanumeric characters for a call number to establish a phone connection and for internal signaling in and between telecommunication networks. An alternative additional dialing method on an alphanumeric basis by using the complete character set of the ASCII character set with its national embodiments (alphanumeric subscriber call number ATR) with any length of the ATR freely set by the subscriber as an optional alternative that coexists with the current dialing method with a decimal number system (NTR). The ATR is sent from the terminal to the switching center and used preferably to establish a connection or converted to an NTR that is used to establish the connection with the target subscriber. The method may be introduced as an overlay process for the existing dialing method within existing networks.
