2.1.2 Supporting the QFE Interface
The ITI8241C-S adapter supports autonegotiation for the Ethernet
interface. The autonegotiation protocol, as specified in the 100BASE-TX
standard, automatically selects the operation mode (half-duplex or full-
duplex) and speed (10 Mbits/s or 100 Mbits/s) based on the network the
adapter is on.
The link speed and modes supported by the ITI8241C-S adapter are
listed below in order of decreasing priority:
•
100 Mbits/s, full-duplex
•
100 Mbits/s, half-duplex
•
10 Mbits/s, full-duplex
•
10 Mbits/s, half-duplex
When you boot your system, an ITI8000 adapter advertises these
capabilities to the Link Partner (a hub, switch, or another Network
Interface Card (NIC) in a host system) at the other end of the link. If the
Link Partner also supports autonegotiation, it will advertise its capabilities
over the link. The common highest priority mode that both sides support
is selected automatically for the link operation.
