The following table describes the labels in this screen.

The NBG2105 supports PPPoE (Point-to-Point Protocol over Ethernet). PPPoE is an IETF standard 
(RFC 2516) specifying how a personal computer (PC) interacts with a broadband modem (DSL, 
cable, wireless, etc.) connection. The PPPoE option is for a dial-up connection using PPPoE.

For the service provider, PPPoE offers an access and authentication method that works with existing 
access control systems (for example Radius).

One of the benefits of PPPoE is the ability to let you access one of multiple network services, a 
function known as dynamic service selection. This enables the service provider to easily create and 
offer new IP services for individuals.
