Patent ID: 7237206

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 includes instructions operable to cause the programmable processor to: receive an input indicating that a graphical user interface element should be displayed, wherein the graphical user interface element has a plurality of components; send a single first message that the graphical user interface element should be displayed by displaying each component of the graphical user interface element; in response to the first message, display the graphical user interface element by displaying each component of the graphical user interface element; after displaying the graphical user interface element by display each component of the graphical user interface element, send a second message if data used to display one of the plurality of components of the graphical user interface element changes, wherein the second message is associated with the one of the plurality of components of the graphical user interface element; and in response to the second message, display the one of the plurality of components of the graphical user interface element associated with the second message; wherein the upstream communication link is a DSX-1 link and the upstream interface includes: a T1 framer in communication with the downstream interface and adapted to communicate with the DSX-1 link; and a pre-equalizer coupled to the T1 framer and the downstream interface and adapted to communicate with the DSX-1 link.
