Advanced Setup

This section contains advanced setup settings. To create a connection you need to define the

Layer 2 interface and the WAN service.

Configuration Types

ADSL is an ATM based technology. The 15xx family of routers support Bridging and Ethernet

over ATM (EoA) configurations and ATM based configurations:



Bridging

Bridging (Layer 2 MAC addressing); uses Ethernet frames.



PPPoE

Point to Point Protocol over Ethernet; encapsulates PPP packet in Ethernet. (RFC 2516)



IPoE

IP over Ethernet (Layer 3 Internet Protocol addressing in Ethernet frames)



PPPoA

Point to Point Protocol over ATM, encapsulates PPP frames in ATM adaption layer 5 (AAL5)

packets.



IPoA

IP over ATM (Layer 3 Internet Protocol addressing in AAL5 packets

To configure a connection, you first configure the connection type. EoA, PPPoA, or IPoA.

1.

Add a Layer 2 interface and select the connection type.

EoA is used for PPPoE, IPoE and Bridge connections. PPPoA and IPoA are AAL5 based

connections

2.

Set the WAN interface

The WAN interface options to select are determined by the Layer 2 interface type.

Add a Layer 2 Interface

1.

In the left hand menu pane, click

Advanced Setup

.

2.

Under Advanced Setup, click Layer2 Interface then ATM Interface, then click the

Add

button.

3.

In the

VPI

and

VCI

text boxes enter appropriate VPI/VCI numbers.

VPI/VCI (Virtual Path Identifier/Virtual Circuit Identifier) values essentially define the ―pipe‖

which sends data from the upstream device to the modem/router. The VPI/VCI values will be

given to you by your ISP.
