Interfaces and signaling contact of the switches
4.3.1
Ethernet interfaces - electrical ports
4.3.1.1
10Base-T / 100Base-TX
Transmission rate
The transmission rate of the electrical ports is 10 Mbps or as Fast Ethernet ports 100 Mbps.
Transmission mode
The transmission mode for 10Base-T / 100Base-TX is specified in the IEEE 802.3i / IEEE
802.3u standards of the Institute of Electrical and Electronic Engineers.
Autonegotiation (automatic detection of the best transmission modes) is default. The order in
which they are selected is:
●
100Base-TX full duplex
●
100Base-TX half duplex
●
10Base-T full duplex
●
10Base-T half duplex
Two communication modes are possible:
●
Half duplex
Two-way alternate transmission mode - it is only possible to either send or receive over
the interfaces at any one time.
●
Full duplex mode
Two-way simultaneous - both communication partners can send and receive at the same
time.
Connections to other switches can use half or full duplex; connections to hubs are possible
only in half duplex mode.
