Configuring Eoa Interfaces; Overview Of Eoa - SMC Networks Barricade SMC7401BRA User Manual

This section describes how to configure an Ethernet-over-ATM
interface on the ADSL Barricade, if one is needed to communicate
with your ISP.

Overview of EOA

The Ethernet-over-ATM (EOA) protocol is often referred to as
RFC1483, which is the Internet specification that defines it. It is
commonly used to carry data between local area networks that
use the Ethernet protocol and wide-area networks that use the
ATM protocol. Many telecommunications industry networks use
the ATM protocol. ISPs who provide DSL services often use the
EOA protocol for data transfer with their customers' DSL modems.
EOA can be implemented to provide a bridged connection between
a DSL modem and the ISP. In a bridged connection, data is shared
between the ISP's network and their customer's as if the networks
were on the same physical LAN. Bridged connections do not use
the IP protocol. EOA can also be configured to provide a routed
connection with the ISP, which uses the IP protocol to exchange
data. Before creating an EOA interface or modifying the default
settings, contact your ISP to determine which type of protocol
they use.

PPP vs. EOA: Your ISP may use a protocol other than
EOA for communication with the ADSL Barricade, such
as the point-to-point protocol (PPP). One type of PPP,
named PPP over Ethernet (PPPoE), actually works on
top of the EOA protocol. The other type, PPP over ATM
(PPPoA), does not. However, if your ISP uses either type
of PPP, you do not need to separately create an EOA
