ABSTRACT:
Methods for accessing full bandwidth in an asynchronous data transfer and source traffic control system include permitting some bus users (e.g. networks cards) to access both odd and even frames while permitting other bus users (e.g. subscriber line cards) to access only odd or even frames. An apparatus according to the invention supports line cards numbering up to 32−(2×the number of network cards). An exemplary embodiment shows a single network card coupled to an OC-12 network link and twenty asymmetric digital subscriber line cards.
