Claim 2

An access device for providing high speed network connectivity, comprising: a main processor for executing code to send and receive proprietary protocol packets for communicating management information with a multiplexer using a digital subscriber line (DSL) technology, the management information indicating presence of an Ethernet-type port, current line speed, and media access control (MAC) address; a modem interface bus coupled to the main processor for providing read/write control signs; a multi-function controller coupled to the main processor for performing Ethernet media access control (MAC); an Ethernet interface coupled to the multifunction controller for communicating with an external Ethernet device; a DSL port coupled to the modem interface bus for receiving and transmitting a DSL signals; a DSL bit pump coupled to the modem interface for performing digital signal processing functions; and a digital/analog converter (DAC) coupled to the DSL bit pump for outputting signals to the DSL bit pump for transport over the DSL port and over the Ethernet interface.

Claim 3

The access device as in claim 1 , wherein the proprietary protocol packets comprises: a line identification field that identifies a subscriber line associated with one of the subscriber DSL modems; a sequence identification field that is used for synchronization between the data frames; a data length field that specifies the length of a data payload within the data frames; and a checksum field for error detection.

Claim 4

Claim 5

The access device as in claim 1 , further comprising: a DSL data interface for receiving and transmitting the DSL signals to and from the DSL port; a plain old telephone service (POTS) line interface coupled to the DSL data interface port for communicating with a public switched telephone network via a POTS signal having a voice band and a data band; and a low pass filter coupled to the POTS line interface for separating the voice band and the data band.

Claim 6

The access device as in claim 2 , wherein the DSL port comprises a RJ-45 connector.

Claim 7

The access device as in claim 1 , wherein the management information comprises lower and upper Service Access Point (SAP) information.

Claim 8

The access device as in claim 1 , wherein the management information comprises a file download module for retrieving a runtime file from the multiplexer.

Claim 9

An access device for providing high speed network connectivity, comprising: a central processing unit (CPU) card comprising: (a) a main processor configured for supplying management information with a multiplexer over a digital subscriber line (DSL), the management information indicating presence of an Ethernet-type port, current line speed, and media access control (MAC) address; (b) a multi-function controller coupled to the main processor for configured for performing Ethernet media access control (MAC); (c) a modem interface bus coupled to the main processor configured for providing read/write control signs; (d) a DSL port coupled to the modem interface bus for receiving and transmitting a DSL signals; and a modem card coupled to the CPU card for interfacing a public switched telephone network (PSTN) comprising: (a) a DSL bit pump coupled to the modem interface of the CPU card configured for performing digital signal processing functions; (b) a digital/analog converter (DAC) coupled to the DSL bit pump for outputting signals to the DSL bit pump for transport over the DSL port and over the Ethernet interface.

Claim 10

An access device for providing high speed network connectivity, comprising: a central processing unit (CPU) card comprising: (a) a main processor configured for supplying management information with a multiplexer over a digital subscriber line (DSL), the management information indicating presence of an Ethernet-type port, current line speed, and media access control (MAC) address; (b) a multi-function controller coupled to the main processor for configured for performing Ethernet media access control (MAC); (c) a modem interface bus coupled to the main processor configured for providing read/write control signs; (d) a DSL port coupled to the modem interface bus for receiving and transmitting a DSL signals; and a modem card coupled to the CPU card for interfacing a public switched telephone network (PSTN) comprising: (a) a DSL bit pump coupled to the modem interface of the CPU card configured for performing digital signal processing functions; (b) a digital/analog converter (DAC) coupled to the DSL bit pump for outputting signals to the DSL bit pump for transport over the DSL port and over the Ethernet interface.

Claim 11

The access device as in claim 8 , further comprising a POTS splitter configured for combining and separating a voice band and a data band associated with signals received from the PSTN.

Claim 12

The access device as in claim 8 , wherein the management information comprises lower and upper Service Access Point (SAP) information.

Claim 13

The access device as in claim 8 , wherein the management information comprises a file download module for retrieving a runtime file from the multiplexer.

Claim 14

The access device as in claim 8 , further comprising: a DSL data interface for receiving and transmitting the DSL signals to and from the DSL port; a plain old telephone service (POTS) line interface coupled to the DSL data interface port for communicating with a public switched telephone network via a POTS signal having a voice band and a data band; and a low pass filter coupled to the POTS line interface for separating the voice band and the data band.
