Method for providing telephone services through xdsl connection lines
First Claim
1. Method for making telephony services available by way of xDSL connection lines, according to which a transport protocol connection is used for the voice channel, and another transport protocol connection is used for the signaling, in order to implement a telephony service, VoIP signaling is used to control the voice transmission between the IAD and the MG, on the one hand, and for transparent transmission of the PSTN/ISDN signaling between the IAD and the VoIP controller, a media gateway (MG) is used to convert voice between VoIP and TDM, a VoIP controller is used that a) handles the PSTN/ISDN signaling, b) terminates the VoIP signaling protocol and uses it for tunneling of the PSTN/ISDN signaling, and c) controls the media gateway (MG), an xDSL access device (IAD) is used, by means of which a) the two ATM connections for voice and signaling are terminated, b) the voice transmission between VoIP and the terminal connection is converted, c) the VoIP signaling protocol is terminated and used for tunneling of the PSTN/ISDN signaling, and d) the voice and PSTN/ISDN signaling are brought together and thereby the terminal connection for the subscriber terminals connected with the xDSL access device (IAD) is operated.

Abstract
The inventive method uses a VoIP server which provides the classical subscriber performance features of an exchange, and a VoIP client in the integrated access device (IAD) of the subscriber. The VoIP server uses a known VoIP signalling protocol for controlling the VoIP voice transmission between the VoIP client in IAD and the media gateway and for tunnelling the PSTN/ISDN signalling between the VoIP client in the IAD and the VoIP server.

2. Telephony service system, with
a VoIP server that makes the conventional subscriber features of a subscriber switching center available, an xDSL access device (IAD) that contains at least one subscriber connection, and that converts the VoIP voice and the PSTN/ISDN signaling tunneled by way of the VoIP signaling protocol to the conventional voice transmission and signaling methods at a subscriber connection, a media gateway that converts the voice between VoIP and TDM, wherein the VoIP server uses a known VoIP signaling protocol (H.323, SIP, etc.) to control the VoIP voice transmission between the xDSL access device (IAD) and the media gateway and for tunneling the PSTN/ISDN signaling between the xDSL access device (IAD) and the VoIP server.

3. VoIP server
that makes the conventional subscriber features of a subscriber switching center available, that uses a known VoIP signaling protocol to control the VoIP voice transmission between the xDSL access device (IAD) and the media gateway, and for tunneling the PSTN/ISDN signaling between itself and the xDSL access device (IAD).
-
4. xDSL access device that
terminates the two transport protocol connections for voice and signaling, converts the voice transmission between VoIP and the terminal connection, terminates the VoIP signaling protocol and uses it for tunneling the PSTN/ISDN signaling, brings the voice and PSTN/ISDN signaling together and thereby operates the terminal connection for subscriber terminals.
-
5. Media gateway that converts the voice between VoIP and TDM and is controlled by a VoIP controller, characterized in that the TDM output of the MG is carried to the VoIP controller.
