Patent ID: 7237204

Claim:
A line interface card, comprising: an upstream interface that sends and receives traffic to an upstream communication link a downstream interface that sends and receives traffic to a downstream communication link an input-output interface adapted to communicate with a display device and with an input device; a programmable processor coupled to the upstream interface, the downstream interface, and the input-output interface; a storage medium coupled to the programmable processor, tangibly embodying program instructions; wherein the program instructions include instructions operable to cause the programmable processor to: cause a first process to: communicate to a second process what data will be used to display a graphical user interface element; cause the second process to: determine if the data used to display the graphical user interface element has changed; and if the data used to display the graphical user interface element has changed, communicate to a third process that the data used to display the graphical user interface has changed; and cause the third process to: receive the communication that the data used to display the graphical user interface has changed; and in response to the communication that the data used to display the graphical user interface element has changed, display the graphical user interface element; wherein the downstream communication link is an HDSL2 link and the downstream interface includes: an HDSL2 framer in communication with the upstream interface and adapted to communicate with the HDSL2 link; and an HDSL2 transceiver coupled to the HDSL2 framer and adapted to communicate with the HDSL2 link.
