  • Patent number: 7092412
    Abstract: A method and apparatus for extending existing fiber and local area networks across digital subscriber lines, at matching data rates is disclosed. A DSL transceiver system is disclosed with one or more gateways coupled to at least one digital signal processor (DSP). The DSP in turn couples to a plurality of analog-front-ends (AFE's). Each AFE is coupled via associated hybrid front ends (HFE's) to corresponding subscriber lines. The transceiver or a controller coupled thereto maintains a table of bandwidth requirements and frame types for a variety of sessions. Individual sessions include bandwidth requirements beyond existing XDSL capabilities. The system determines frametype, e.g. 802 and bandwidth requirements, e.g. 100 Mbps for each session and allocates more than one subscriber line accordingly. For each session the divergent bandwidth availability of each of the subscriber lines to which the DSP may be coupled is determined and all or a portion of that bandwidth is allocated to the selected session.
