Abstract
The invention concerns a method of making changes in a directory number administration (DNA), a directory number administration facility whereby changes are made in accordance with this method, and a method for providing a directory number administration service via such a directory number administration. The directory number administration (DNA) manages the assignment of a quantity of subscriber stations to call numbers. To make a change in this assignment, a change order is entered into the directory number administration and the change takes place when the change order is executed by the directory number administration (DNA). However the change order is not executed immediately by the directory number administration (DNA) when a change order is entered. A connection is established between a subscriber terminal (TE) and the directory number administration (DNA), and a trigger message (TRIG) is sent from the subscriber terminal (TE) to the directory number administration (DNA) via the established connection. The execution of the change order is finally released when the trigger message (TRIG) is received.
