  • Patent number: 8379661
    Abstract: Methods and systems for customer premise equipment (CPE) to reverse the upstream speed and downstream speed of a network connection (e.g., ADSL connection) are described. The CPE is communicating with a network device via the network connection. Originally, the CPE's downstream speed with the network device significantly exceeds the CPE's upstream speed with the network device. A speed reversal signal is forwarded from the CPE to the network device. The signal requests the network device to reverse the CPE's downstream speed and upstream speed with the network device. The network device retrains the CPE. The CPE communicates with the retrained network device with an upstream speed that significantly exceeds the downstream speed.
