Abstract: The invention concerns a method for supporting communication between a switching system and a PSTN terminal connected with a network termination unit through an analog subscriber line. Broadband traffic packets as well as a number of synchronous channels are transferred in both directions over a subscriber line between the network termination unit and the subscriber line board of the switching system. At least one ISDN-B channel and one ISDN-D channel is provided based on such synchronous channels. A protocol converter converts between an analog loop signaling applied on the analog subscriber line and digital signaling messages transported over the ISDN-D channel. An analog to digital conversion is performed between the analog subscriber line and the ISDN-B channel.

Abstract: The invention concerns a method and a gateway for transporting stream traffic over an IP network. A gateway receives stream data assigned to different stream data channels. The gateway allocates two or more stream data channels to a stream service emulation tunnel provided by IP packets periodically transmitted over the IP network. A packetization unit packs the stream data of the allocated two or more stream data channels in IP packets assigned to said stream service emulation tunnel. Further, it periodically sends these IP packets over the IP network, wherein such IP packets contain stream data of two or more different stream data channels.
