Twisted-Pair Ports
These ports support the automatic MDI/MDIX crossover detection function
which provides true ‘plug and play’ capability without the need of confusing
crossover cables or crossover ports.
With the Auto-MDI function, you simply plug-in the network cable to the
unit directly with no need to care if the end node is a NIC (Network Interface
Card) or switches and hubs.
