  • Systems and methods for achieving improved ADSL data rates over USB 1.1 channel
    Publication number: 20060153196
    Abstract: A system for achieving improved isochronous downstream data throughput rates between a DSL modem and a destination device, such as a PC, over a USB 1.1 data channel. An asynchronous transfer mode signal is received by a DSL modem. After normal signal processing, a controller in the modem executes a compression algorithm to strip the redundant ATM header information from each cell. A serial data stream containing the compressed ATM cells are then transferred to the destination device over USB 1.1 channel. A software driver stored at the destination device decompresses the compressed ATM signals for normal reassembly. Because only the data payload portion of each ATM cell is transferred to the destination device, the full 8.184 Mbits/s of the USB channel is used to transfer data, thereby increasing the effective data throughput rate.
