Configuration of the WAN interfaces
Your gateway can also be used as an ISDN or PPPoE (PPP over Ethernet) router.
In this case it deals with the transmission of TCP/IP data between your local net-
work and the WAN connection, regardless of whether this concerns voice or other
data.
The equipment provide various options for routing in the WAN. To use ISDN as a
WAN interface is a standard feature of the IP 400. The IP 400 supports PPPoE on
the WAN interface.
Fig. 5 Using the gateway as an ISDN router
Any ISDN or PPPoE router with PPP capability can serve as a PPP remote entity.
