Design Features
The Fast EtheRx dual-speed hub complies with the full set of repeater basic functions as defined by IEEE802.3u 100BASE-TX, IEEE802.3i 10BASE-T, and IEEE802.3 CSMA/CD standards.
Repeater Functions
If any single port senses the start of a valid packet on its receiving line, the dual-speed hub will re-transmit the received data to all other ports on the network. The re-transmission of packets complies with the IEEE 802.3 specification in terms of preamble structure, voltage amplitude, and timing characteristics.
Auto-Negotiation
Auto-Negotiation provides the means of automatically establishing a link by detecting the link capabilities of the connected device on the network to select the best operational mode available (i.e. 10/100Mbps selection)
Receive Jabber Protection
The dual-speed hub uses a Receive Jabber Protection scheme to ensure that the network is not disabled due to reception of excessively long data packets.
Collision-Handling
The dual-speed hub will detect and respond to collision conditions as outlined in the IEEE 802.3 specifications.
Error-Handling
With 100BASE-TX Fast Ethernet, the new error-handling feature prevents sub- standard links from generating streams of false carrier and interfering with other links.
Automatic Port Partitioning / Reconnection
If any of the ports on the dual-speed hub experience excessive collisions, or faulty conditions, that particular port can be partitioned. Once partitioned, the hub will continue to monitor that port. If the error conditions have been corrected or a good data packet is received or transmitted without a collision, the hub will automatically reconnect that port to the network.
