Patent ID: 7324503

Claim:
A method for making telephony services available by way of xDSL connection lines, comprising: providing a transport protocol connection for the voice channel, and another transport protocol connection is used for the signaling to implement a telephony service; controlling the voice transmission between the IAD and the MG, using VoIP signaling, and for transparent transmission of the PSTN/ISDN signaling between the IAD and the VoIP controller; converting voice between VoIP and TDM using a media gateway; providing a VoIP controller to handle the PSTN/ISDN signaling, terminate the VoIP signaling protocol and for tunneling of the PSTN/ISDN signaling, and control the media gateway; and providing an xDSL access device to terminate the two ATM connections for voice and signaling, convert the voice transmission between VoIP and the terminal connection, terminate the VoIP signaling protocol and for tunneling of the PSTN/ISDN signaling, and bringing together the voice and PSTN/ISDN signaling and the terminal connection for the subscriber terminals connected with the xDSL access device is operated.
