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 retrans-
mits them to all other ports operating at 10Mbps. Similarly, the 100Mbps
repeater retransmits Fast Ethernet transmissions from ports operating at
100Mbps to all other ports operating at the same speed.
