ATM Interface

Clicking on the ATM VC brings up the following screen. The Belgacom b-box uses ATM as

its WAN interface. Protocols including 1483 Routing, 1483 Bridging, MAC Encapsulated

Routing (MER), PPPoA and PPPoE with LLC-SNAP and VC-Mux encapsulations are

supported for each ATM PVC.

When you have finished entering your connection parameters, click “SAVE SETINGS.” You can

verify that you have established an ADSL connection by clicking Status at the bottom of the left-

hand menu. See “Status” on page 4-86.

See the table below for a description of the parameters.

Parameter Description

Protocol

 Disable: Disables the connection.

 1483 Bridging: Bridging is a standardized layer 2 technology. It is typically used in

corporate networks to extend the physical reach of a single LAN segment and increase

the number of stations on a LAN without compromising performance. Bridged data is

encapsulated using the RFC1483 protocol to enable data transport.

 PPPoA: Point-to-Point Protocol over ATM is a method of encapsulating data for

transmission to a far point.

 1483 Routing: 1483 Routing allows a simple, low-cost connection to the Internet via a

standard Ethernet port. The router looks up the network address for each packet seen on

the LAN port. If the address is listed in the routing table as local, it is filtered. If the

address is listed under the ADSL port, it is forwarded. Or if the address is not found, then

it is automatically forwarded to the default router (i.e., the Belgacom b-box at the head

end).
