This paper proposes an upgrade scenario for xDSL networks to provide broadband access for extendedlink lengths while demonstrating network grooming bymeans of more than one subscriber using a single network connection concurrently. This is achieved by applying Direct Spread Code Division Multiple Access (DS-CDMA) in a Fiber-to-the-Cabinet (FTTC) topology by means of a Field Programmable Gate Array (FPGA), used to demonstrate simultaneous user transmission and System-on-Chip (SoC) network element generation. Experimental results have displayed efficiency in ADSL link rates of 66% and 41% for back-to-back and 12km-reach fiber links respectively.
