Global functions / operating modes
Auto-Crossing:
• Automatic detection of a crossing of outgoing and incoming lines on twisted-
pair interfaces.
• Allows the connection of both a single-strand cable and a crossover cable.
Auto-negotiation
• Switches handle the data rate with the link partner on each port independently
and automatically.
• The link is established with the highest possible common data rate both
partners can handle.
Blocking:
• Non-blocking – if the capacity of the switches is adequate to master
connections with full data rate between the partners
• Blocking – if no connections can be established because of overload
Half-duplex:
• Operating mode in which one Ethernet component either sends or receives
data at a specic time
Full-duplex:
• Both communication partners can communicate in both directions at the
same time.
