The following table describes the labels in this screen.
Table 8 Network Setting > Broadband > Add New WAN Interface/Edit (Routing Mode)
LABEL DESCRIPTION
General
Active Select this to enable the interface.
Name Specify a descriptive name for this connection.
Type Select whether it is an ADSL/VDSL over PTM, ADSL over ATM connection or Ethernet.
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.
The choices depend on the connection type you selected. If your connection type is ADSL/
VDSL over PTM, 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 The choices in this field change according to the Encapsulation method chosen above. This
field is not editable. PPPoA and IPoA encapsulation use the same named DSL Link Type.
Ethernet-over-ATM (EoA) is used for PPPoE, and IPoE encapsulation.
EoA a protocol for data transfer between Ethernet LAN and WAN over the ATM protocol. It
creates a bridged connection between the VMG and the ISP. It 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.
Encapsulation
Mode
Select the method of multiplexing used by your ISP from the drop-down list box. Choices
are:
• LLC/SNAP-BRIDGING: In LCC encapsulation, bridged PDUs are encapsulated by
identifying the type of the bridged media in the SNAP header. This is available only when
you select IPoE or PPPoE in the Select DSL Link Type field.
• VC/MUX: In VC multiplexing, each protocol is carried on a single ATM virtual circuit
(VC). To transport multiple protocols, the VMG needs separate VCs. There is a binding
between a VC and the type of the network protocol carried on the VC. This reduces
payload overhead since there is no need to carry protocol information in each Protocol
Data Unit (PDU) payload.
• LLC/ENCAPSULATION: More than one protocol can be carried over the same VC. This
is available only when you select PPPoA in the Encapsulation field.
• LLC/SNAP-ROUTING: In LCC encapsulation, an IEEE 802.2 Logical Link Control (LLC)
header is prefixed to each routed PDU to identify the PDUs. The LCC header can be
followed by an IEEE 802.1a SubNetwork Attachment Point (SNAP) header. This is
available only when you select IPoA in the Encapsulation field.
