Arrangement for obtaining information from a switching system database by an adjunct processor

摘要

To obtain its own copy of directory information from a database (111) of a switching system (10), an adjunct processor such as a voice-mail system (11) either uses the "directory" feature of the switching system by emulating use of the feature by a digital display telephone (140), or uses a remote administration and maintenance port (119) by emulating use of the port by a remote administration terminal (145).
