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 . If your connection type is Ethernet , the choices are PPPoE and
IPoE .
IPv4/IPv6 Mode Select IPv4 Only if you want the XMG to run IPv4 only.
Select IPv4 IPv6 DualStack to allow the XMG to run IPv4 and IPv6 at the same time.
Select IPv6 Only if you want the XMG 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.
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 XMG 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.
Service
Category Select UBR Without PCR or UBR With PCR for applications that are non-time sensitive, such as e-
mail.
Select CBR (Continuous Bit Rate) to specify fixed (always-on) bandwidth for voice or data traffic.
Select Non Realtime VBR (non real-time Variable Bit Rate) for connections that do not require
closely controlled delay and delay variation.
Select Realtime VBR (real-time Variable Bit Rate) for applications with bursty connections that
require closely controlled delay and delay variation.
IP Address (This is available only when you select IPv4 Only or IPv4 IPv6 DualStack in the IPv4/IPv6 Mode field.)
Obtain an IP
Address
Automatically A static IP address is a fixed IP that your ISP gives you. A dynamic IP address is not fixed; the ISP
assigns you a different one each time you connect to the Internet. Select this if you have a
dynamic IP address.
DHCP
option 60/
Vendor ID
This field displays when editing an existing WAN interface. Type the class vender ID you want the
XMG to add in the DHCP Discovery packets that go to the DHCP server.
DHCP
option 61
IAD
This field displays when editing an existing WAN interface. Type the Identity Association Identifier
(IAD) you want the XMG to add in the DHCP Discovery packets that go to the DHCP server.
DHCP
option 61
DUID
This field displays when editing an existing WAN interface. Type the DHCP Unique Identifier (DUID)
you want the XMG to add in the DHCP Discovery packets that go to the DHCP server.
