  • Dynamic retrieval of region code for network devices on data communication networks
    Patent number: 11907069
    Abstract: In network devices, during manufacturing, input for designation of a region code to be a non-specific region code is stored in a BIOS memory of the network device, and a specific region code is stored off the BIOS. During boot up, the BIOS is checked for a specific region code to regulate wireless transmissions at a physical location of operation. Responsive to receiving the non-specific region code from BIOS, the specific region code is requested from a region code server based on a network device identifier. Once received, the region code is stored in flash memory, until rebooted or otherwise reset, rather than BIOS.

  • Cross-connect with shared storage
    Patent number: 6888825
    Abstract: A method and apparatus for sharing storage in a cross-connect. According to one embodiment of the invention, a cross-connect includes a number of sets of data input lines and a number of matrices. Each of the sets of data input lines is to be coupled to a different line card. Each of the matrices is coupled to every one of the sets of data input lines. In addition, each of the matrices has a set of data output lines, where the set of data input lines of each of the matrices is to be coupled to a different one of the line cards.
