Abstract

An upstream transceiver, coupled to an upstream end of a long haul, single digital subscriber loop of an extended range asymmetrical digital subscriber line communication system, 'spoofs' a (co-located) digital subscriber line access multiplexer to reduce its downstream data rate over a short haul loop to the upstream transceiver. The reduced downstream data rate is compatible with the data rate that can be supported by the long haul loop and also accommodates an auxiliary (64K) POTS channel thereover. The reduced data rate may be derived by preliminary signal quality measurements upon the long communication loop conducted between the upstream transceiver and a downstream transceiver coupled to a remote end of the long haul loop.
