The assignment corresponds to the Ethernet standard for an RJ45 connector.
•
When autonegotiation is deactivated, the RJ45 socket is allocated as a switch (MDI-X).
•
If autonegotiation is activated, then autocrossing is active and the RJ45 socket has either a
device assignment (MDI) or switch assignment (MDI-X).
