Patent ID: 8275006

Claim:
A method for binding transmission lines, comprising: deciding, by a broadband access device, a transmission speed supported by all the transmission lines to be bound, wherein all the transmission lines to be bound are digital-subscriber-line (DSL) transmission lines that correspond to a same DSL interface provided for a user by the broadband access device; activating, by the broadband access device, all the transmission lines to be bound at the transmission speed supported by all the transmission lines, and binding all the transmission lines; sending, by the broadband access device, data to a peer side device via the bound transmission lines according to a first bind-sending rule; and receiving, by the broadband access device, data via the bound transmission lines from the peer side device according to a second bind-sending rule stored in the broadband access device; wherein the first bind-sending rule is different from the second bind-sending rule.
