摘要

The method involves transmitting the connection requests from the subscriber stations to a switching center (3). The speech signals (10) and additional signals (13) are transmitted over an audio channel (14) between the switching center and a remote station (4) during a telephonic connection between the subscriber stations and the remote station. The additional signals contain signaling data (11) to the connection request. The signaling data is received during the telephonic connection of other subscriber stations. An independent claim is included for a system for establishing a telephonic connection.
