Broadband: Add/Edit: PPPoE Encapsulation
LABEL DESCRIPTION
General
Active Select this to activate the WAN configuration settings.
Name Specify a descriptive name for this connection. This field is view only if you are
editing the WAN connection.
Type Select whether it is ADSL/VDSL over PTM, ADSL over ATM, or Ethernet
connection.
• ADSL/VDSL over PTM: The VDSL Router uses the VDSL technology for
data transmission over the DSL port.
• ADSL over ATM: The VDSL Router uses the ADSL technology for data
transmission over the DSL port.
• Ethernet: The VDSL Router transmits data over the Ethernet WAN port.
Select this if you have a DSL router or modem in your network already.
Mode Select Routing (default) from the drop-down list box if your ISP give you one IP
address only and you want multiple computers to share an Internet account.
Encapsulation Select the method of encapsulation used by your ISP from the drop-down list
box. This option is available only when you select Routing in the Mode field.
• PPP over Ethernet (PPPoE): PPPoE (Point to Point Protocol over Ethernet)
provides access control and billing functionality in a manner similar to dial-
up services using PPP. Select this if you have a username and password for
Internet access.
• IP over Ethernet (IPoE): In this type of Internet connection, IP packets
are routed between the Ethernet interface and the WAN interface and then
formatted so that they can be understood in a bridged environment.
• PPP over ATM (PPPoA): PPPoA allows just one PPPoA connection over a
PVC.
• IP over ATM (IPoA): IPoA allows just one RFC 1483 routing connection
over a PVC.
If your connection type is ADSL/VDSL over PTM or Ethernet, the choices are
PPPoE and IPoE.
If your connection type is ADSL over ATM, the choices are PPPoE, PPPoA,
IPoE and IPoA.
ATM PVC Configuration (These fields appear when the Type is set to ADSL over ATM.)
VPI The valid range for the VPI is 0 to 255. Enter the VPI assigned to you.
VCI The valid range for the VCI is 32 to 65535 (0 to 31 is reserved for local
management of ATM traffic). Enter the VCI assigned to you.
DSL Link Type This field is not editable. The selection depends on the setting in the
Encapsulation field.
EoA (Ethernet over ATM) uses an Ethernet header in the packet, so that you can
have multiple services/connections over one PVC. You can set each connection
to have its own MAC address or all connections share one MAC address but use
different VLAN IDs for different services. EoA supports ENET ENCAP (IPoE),
PPPoE and RFC1483/2684 bridging encapsulation methods.
PPPoA (PPP over ATM) allows just one PPPoA connection over a PVC.
IPoA (IP over ATM) allows just one RFC 1483 routing connection over a PVC.
