EoA

Interfaces

This section describes how to configure an Ethernet-over-ATM interface on
the HM210dp/di, if one is needed to communicate with your ISP.

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.
