The present invention provides a communication control system that monitors a status of a transmission line, and can dynamically change a communication band used by a communication device included in an access line based on the monitored result. But rather than searching all possible segments of each standard stream, the database includes a set of index files that reference a number of different segments in the repository. Within the insulator, an intralevel wiring is arranged on a wiring plane as a plane including an inactive or active surface of any of the semiconductor chips structuring the first or second chip block. The users are also able to iteratively improve on a previous GR SMART generated solution as additional detail becomes available from the customers during the course of the sales engagement cycle.
