A method and an apparatus are described which enable a connection with a variable bandwidth from a subscriber terminal in an Integrated Services Digital Network (ISDN) to a data network, such as the Internet. The D channel or one or both B channels may be used, and the bandwidth may be adjusted while the connection is maintained, by connecting and/or disconnecting channels, in dependence of the data traffic requirements and the need for the B channels for telephony purposes. |
