Manually Configuring your Modem

ATM Interface

Clicking on the ATM VC brings up the following screen. The Modem 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 the table for a description of the parameters.

Manually Configuring your Modem

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 Modem 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
		Modem (i.e., the Modem at the head end).
	•	PPPoE: Point-to-Point over Ethernet is a common
		connection method used for xDSL.
	•	MAC Encapsulated Routing: If your ADSL service
		is a Bridged mode service and you want to share
		the connection to multiple PC’s, please select
		MAC Encapsulated Routing. MER is a protocol
		that allows you do IP routing with NAT enabled.
VPI/VCI	See Virtual Path Identifier (VPI) and Virtual Circuit
	Identifier (VCI). Data flows are broken up into fixed
	length cells, each of which contains a Virtual Path
	Identifier (VPI) that identifies the path between two
	nodes, and a Virtual Circuit Identifier (VCI) that
	identifies the data channel within that virtual path.
	Each virtual circuit maintains a constant flow of
	cells between the two end points. When there is
	no data to transmit, empty cells are sent. When
	data needs to be transmitted, it is immediately
	inserted into the cell flows.
