Concept

The figure below shows the concept of the SpeedTouch™ PPPoE Relay:

To the PPPoE Relay, you are able to connect 1 or multiple:

host PPPoE clients, which can be any kind of Ethernet interface, such as:

a logical Ethernet interface

the Ethernet interface Bridge

an Ethernet interface which is connected to an ATM interface

PPPoE servers which can be any kind of Ethernet interface, such as:

a logical Ethernet interface

the Ethernet interface Bridge

an Ethernet interface which is connected to an ATM interface

embedded PPPoE clients

PPPoE Relay

1 or more embedded 

PPPoE client(s)

1 or more 

PPPoE Server(s)

1 or more host 

PPPoE client(s)
