Dual-Speed Ethernet Hub
Technology Overview
Dual-speed Ethernet hubs have been developed to make it simpler to
plan networks containing both 10Mbps Ethernet and 100Mbps Fast
Ethernet technologies, especially when network hosts are being
gradually migrated to new Fast Ethernet connections.

A dual-speed hub is actually two repeaters in one enclosure. The
10Mbps repeater receives Ethernet transmissions from any of its
ports, and retransmits them to all other ports operating at 10Mbps.
Similarly, the 100Mbps repeater retransmits Fast Ethernet trans-
missions from ports operating at 100Mbps to all other ports operating
at the same speed.
