Note 1:
Collisions are not detected by the device operating in full-duplex mode: packets from this device are
never re-transmitted if a collision occurs on them.
The following table lists all possible Ethernet port configuration combinations when connecting
an IP Touch set to an external device (switch on LAN side, PC on PC side). For each combination,
the table shows the link status: valid or invalid (duplex or speed mismatch), as described above.
