What is Dual-Speed and how does it work?
Dual Speed means that the twelve RJ-45 ports of the DS12 will function at either 10Mb/s or 100Mb/s. An auto-sensing function is present on the DS12 (not on DS12E) that allows each port to sense a link-whether its operation is to be at 100Mb or 10Mb. If no auto-negotiating device is connected, the default speed is 10Mb. A bridge is included in the Blade hub to interconnect the two traffic domains of the DS12. The bridge filters and selectively forwards packets to allow the necessary packets to cross between 10Mb and 100Mb traffic domains, enabling all users of either the 100 or 10Mb domains to communicate with each other.
