ABSTRACT:
A novel architecture for high speed dual symmetric full duplex operation of otherwise asymmetrical telephone subscribers--central office modems that provide relatively high data rate downloading from the telephone central office but relatively low data rate uploading from the subscriber stations, whereby, through direction swapping by such duplex operation, equal downloading and uploading can be achieved, or other increasing or grate swapping or variation of the uploading rate capability, as desired. ADSL modems in particular, being reconfigured to provide symmetrical rate downloading and uploading and/or configured direction assignment of rates.
