Internal switch links 10Mbps 100Mbps segments

Dual-Speed hub with internal switching function automatically switches data traffic between devices running at different speed, which allows communications between ports running at 10Mbps and ports running at 100Mbps. Dual-Speed hub with internal switching function can save money by eliminate the need to purchase expensive Switches for users with mixed speed network environment. The connection of the Dual- Speed hub with internal switching function is illustrated as in Figure 1-3:
