Claims (5)

1. Schaltung eines Telefons oder einer Telefonanlage, durch welche eine Verbindung zu einem örtlichen Telefonnetz herstellbar ist und durch welche gewählte Ziffern als Ziffernfolge in das örtliche Netz eingegeben bzw. weitergeleitet werden, dadurch gekennzeichnet, daß eine Verzweigungsschaltung vorgesehen ist, welche in Abhängigkeit davon, ob nach der Verbindung mit einem örtlichen Telefonnetz eine Null als erste Ziffer einer gewählten Ziffernfolge eingegeben wurde, diese als erste Ziffer auftretende Null in eine Ziffernfolge konvertiert, die anstelle der führenden Ziffer Null in das örtliche Telefonnetz weitergeleitet wird, wobei die gewählte Ziffernfolge im übrigen unverändert in das örtliche Telefonnetz eingegeben bzw. weitergeleitet wird.1. Circuit of a telephone or a telephone system through which a connection to a local telephone network can be established and through which dialed digits are entered or forwarded as a sequence of digits into the local network, characterized in that a branching circuit is provided which, depending on, whether a zero has been entered as the first digit of a dialed sequence of digits after connecting to a local telephone network, converts this zero as the first digit into a digit sequence that is forwarded to the local telephone network instead of the leading digit zero, the selected digit sequence remaining unchanged is entered or forwarded into the local telephone network. 2. Schaltung nach Anspruch 1, dadurch gekennzeichnet, daß sie einen Mikroprozessor mit einem Speicher aufweist, der mindestens die erste nach einer Ortsnetzverbindung gewählte Ziffer erfaßt und zwischenspeichert und nach einer logischen Abfrage entweder unverändert an das örtliche Telefonnetz weiterleitet, oder, falls die erste gewählte Ziffer eine Null ist, diese durch eine gespeicherte Ziffernfolge ersetzt.2. Circuit according to claim 1, characterized in that it has a microprocessor a memory that has at least the first after a local network connection dialed digit and cached and after a logical query either forwarded unchanged to the local telephone network or, if the first selected digit is a zero, it is replaced by a stored sequence of digits. 3. Schaltung nach Anspruch 2, dadurch gekennzeichnet, daß der Speicher für die Speicherung mindestens einer 20-stelligen Teilnehmernummer ausgelegt ist.3. Circuit according to claim 2, characterized in that the memory for the Storage of at least one 20-digit subscriber number is designed. 4. Schaltung nach Anspruch 2 oder 3, dadurch gekennzeichnet, daß ein Speicher für die Speicherung von mindestens bis zu 100 zweistelligen Ziffernfolgen vorgesehen ist, die für den Vergleich mit den auf eine führende Null folgenden, gewählten Ziffern vorgesehen sind.4. Circuit according to claim 2 or 3, characterized in that a memory for the Storage of at least up to 100 two-digit sequences of digits is provided for comparison with the dialed digits following a leading zero are provided. 5. Schaltung nach einem der Ansprüche 1 bis 4, dadurch gekennzeichnet, daß eine Verriegelung vorgesehen ist, welche die Weiterleitung der zweiten und aller weiteren gewählten Ziffern in das örtliche Telefonnetz mindestens so lange blockiert, bis die Analyse, Erfassung und Weiterleitung der ersten Ziffer bzw. deren Ersetzung und Weiterleitung einer gespeicherten Ziffernfolge abgeschlossen ist.5. Circuit according to one of claims 1 to 4, characterized in that a Lock is provided, which the forwarding of the second and all others dialed digits blocked in the local telephone network at least until the Analysis, recording and forwarding of the first digit or its replacement and Forwarding of a stored sequence of digits is complete.
