Abstract
The present invention discloses a DSL subscriber board with an increasable bandwidth and a method for increasing bandwidth of a DSL subscriber board; the bandwidth of interfaces between chips of the DSL subscriber board can be increased to a predefined bandwidth according to a required amount. The method specifically includes: increasing the number of the interface; increasing the bandwidth rate of the interface; or increasing the clock frequency of the interface. Both the DSL subscriber board and the method for increasing the bandwidth of the DSL subscriber board can increase the processing bandwidth of the DSL subscriber board efficiently, and thereby increasing the number of subscribers of the DSL subscriber board and reducing cost efficiently. At the same time, it can also improve the bandwidth of the DSL subscribers to accommodate to the development of future DSL high bandwidth technologies.
