Ethernet concept

Aastra 470 provides three GBit Ethernet interfaces, which are routed to the front
panel of the call manager card. They are used to connect to the customer's data
network (LAN) and e.g. the IP connection with an SIP provider. The socket marked
"WAN" currently has no function and remains covered.
Likewise the Ethernet interface on the front panel of the applications card is not
used as the applications server is accessed via the WebAdmin configuration tool.
As the following schematic diagram shows, all the cards are internally connected
with one another via Ethernet.
