Abstract
A multimode DSL (digital subscriber line) line driver circuit is disclosed. The line driver circuit includes a switch network that enables the line driver circuit to be switched between multiple DSL communication configurations. Upon receipt of a mode control signal, the line driver circuit switches from a first DSL communication configuration to a second communication configuration. A DSL communication signal configured according to the second DSL communication configuration is received at the line driver circuit. The received DSL communication signal is amplified and/or filtered by the line driver circuit. The received DSL communication signal is transmitted from the line driver circuit. In one example implementation, the line driver circuit may be switched from an asymmetric digital subscriber line (ADSL) configuration to a very high speed digital subscriber line (VDSL) configuration, and may be switched from the VDSL configuration to the ADSL configuration.
