‘Communicate’ means all users at 4 Ethernet ports of local end can communicate either each
other or with users at remote end.
“Isolated on local end” means users, at 4 Ethernet ports of local end, isolate each other; but can
communicate with users at remote end.
“isolated oppositely on two sides” means the 1
st
port of local end can communicate with the 1
st
port of remote end, the 2
