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.
