• the target or the target points of the information to be transmitted are determined by clearly specified addresses or signaling information.
• the destination points are defined by clearly assigned international numbers or subscriber numbers. Due to the digital switching devices used in the current telephone networks, an independent
• the communication devices or terminal devices arranged in a telephone network are connected to the respectively assigned subscriber switching devices via connection devices or interface cards - also referred to as a port.
• a specific telephone number is assigned to each subscriber connected to a switching device via a port by means of a management system. With ISDN connections, several phone numbers can also be assigned to one subscriber.
• an international phone number is defined by ITU-T recommendation E.164. According to this recommendation, a telephone number can have a maximum of 15 digits - without traffic exclusion numbers. According to recommendation E.164, an international number consists of:
• CC Country Code
• LKZ country code
• NDC National Destination Code
• area code also called area code
• this can be a local area code (ONKz)
• service code eg 800
• network code eg 172 for the network operator "ARCOR”
• the number can also be preceded by traffic exclusion numbers, for example to identify national (0) or international (00) connections.
• the subscriber number assigned to a subscriber can address a main connection or a terminal within a telecommunications system - when dialing to the telecommunications system.
• the country code for Germany is set at 49. This is valid globally for all telephone networks. In this case, 13 digits remain for the formation of a national number, which, depending on the division of the telephone networks, can be divided between the area code or area code and the subscriber number.
• a local area network represents a numbering range, the call number must always be dialed when establishing a connection within a local area network, even if the desired subscriber or the desired communication terminal is connected to the same switching device and, in principle, a shorter internal call number within the switching device is sufficient for establishing the connection would.
• This type of number assignment is also referred to as "covert numbering" or “covert dialing”. If a connection is established from the long-distance network, the caller must know from the external long-distance network that the desired communication terminal or the desired "B subscriber" is assigned to another local area network.
• the initiator of the connection must then not only dial the local area code, he must also dial the traffic elimination number beforehand - for example "0" - to indicate that he has left his local network.
• the continuation of operational tasks is retained while the still valid, not updated or "old" subscriber numbers are retained.
• the subscriber-specific information assigned to a subscriber and stored in the communication network can both be read out while maintaining the still valid "old" number plan - i.e. read access to a database stored in the communication network - as well as being changed or edited - i.e. write access to the database.

Due to the advantageous further development, in addition to the subscriber-specific information stored in the communication network, the subscriber call numbers transmitted when establishing a connection are also converted or converted as required, so that a database that has not yet been updated or "outdated” after the time of the update interfaces facing outwards are presented as a "new" database.
• signaling information transmitted after the update point in time is checked in the context of a communication relationship to establish whether it is designed in accordance with the signaling rule valid before the update point in time.

It can thus be determined in a simple and quick manner - e.g. by evaluating the first digits of the signaling information transmitted when a communication relationship is established - according to which signaling rule the signaling information transmitted when establishing a communication relationship is designed and a corresponding establishment of the communication relationship is initiated.
