Table 8 Routing Mode (continued)
LABEL DESCRIPTION
Type Select whether it is ADSL/VDSL over PTM, ADSL over ATM, or Ethernet connection.
• ADSL/VDSL over PTM: The Device uses the VDSL technology for data transmission
over the DSL port.
• ADSL over ATM: The Device uses the ADSL technology for data transmission over the
DSL port.
• Ethernet: The Device transmits data over the Ethernet WAN port. Select this if you have
a DSL router or modem in your network already.
Mode Select Routing 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.
IPv6/IPv4 Mode Select IPv4 Only if you want the Device to run IPv4 only.
Select IPv6/IPv4 DualStack to allow the Device to run IPv4 and IPv6 at the same time.
Select IPv6 Only if you want the Device to run IPv6 only.
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.
