3. 2. 3 Ethernet concept
Mitel 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.
