Abstract
An ADSL access device controls communication through one or more ADSL channels. The ADSL access device may be located at a customer location or at a central office. The access device includes an ADSL modem coupled to the ADSL channel, a protocol converter for converting the protocol of data packets and one or more switching port controllers. Each switching port controller in an ADSL access device at a customer location performs data packet filtering on a local area network and forwards data packets to the ADSL channel or to another LAN port. The switching port controllers in the central office ADSL access device control routing of data packets between different ADSL channels and a wide area network.
