IPv6 Address (This is available only when you select
IPv6/IPv4 DualStack
or
IPv6 Only
in the
IPv6/IPv4
Mode
field.)
IPv6 Address
Select
Automatic
if you want to have the Device use the IPv6 prefix from the connected
router’s Router Advertisement (RA) to generate an IPv6 address.
Select
Get IPv6 Address From DHCPv6 Server(IA_NA)
if you want to obtain an IPv6
address from a DHCPv6 server. The IP address assigned by a DHCPv6 server has priority
over the IP address automatically generated by the Device using the IPv6 prefix from an
RA. This option is available only when you choose to get your IPv6 address
automatically.
Select
Prefix Delegation(IA_PD)
to use DHCP PD (Prefix Delegation) which enables
the Device to pass the IPv6 prefix information to its LAN hosts. The hosts can then use
the prefix to generate their IPv6 addresses.
Select
Static
if you have a fixed IPv6 address assigned by your ISP.
Select
None
to not assign any IPv6 address to this WAN connection.
WAN IPv6
Address
Enter the IPv6 address assigned by your ISP.
Prefix
Length
Enter the address prefix length to specify how many most significant bits in an IPv6 address
compose the network address.
Next Hop
Enter the IP address of the next-hop gateway. The gateway is a router or switch on the
same segment as your Device's interface(s). The gateway helps forward packets to their
destinations.
IPv6 Routing Feature (This is available only when you select
IPv6/IPv4 DualStack
or
IPv6 Only
in the
IPv6/IPv4 Mode
field. You can enable IPv6 routing features in the following section.)
MLD Proxy
Enable
Select this checkbox to have the Device act as an MLD proxy on this connection. This allows
the Device to get subscription information and maintain a joined member list for each
multicast group. It can reduce multicast traffic significantly.
Apply as
Default
Gateway
Select this option to have the Device use the WAN interface of this connection as the system
default gateway.
IPv6 DNS
Server
Configure the IPv6 DNS server in the following section.
IPv6 DNS
Select
Dynamic
to have the Device get the IPv6 DNS server addresses from the ISP
automatically.
Select
Static
to have the Device use the IPv6 DNS server addresses you configure
manually.
IPv6 DNS
Server 1
Enter the first IPv6 DNS server address assigned by the ISP.
IPv6 DNS
Server 2
Enter the second IPv6 DNS server address assigned by the ISP.
VLAN (These fields appear when the
Type
is set to
ADSL/VDSL over PTM
.)
Active
Select this option to add the VLAN tag (specified below) to the outgoing traffic through this
connection.
802.1p
IEEE 802.1p defines up to 8 separate traffic types by inserting a tag into a MAC-layer frame
that contains bits to define class of service.
Select the IEEE 802.1p priority level (from 0 to 7) to add to traffic through this connection.
The greater the number, the higher the priority level.
802.1q
Type the VLAN ID number (from 1 to 4094) for traffic through this connection.
QoS
Rate Limit
Enter the rate limit for the connection. This is the maximum transmission rate allowed for
traffic on this connection.

ATM PVC Configuration (These fields appear when the
Type

.)
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.
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 Device 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.
Peak Cell Rate
Divide the DSL line rate (bps) by 424 (the size of an ATM cell) to find the Peak Cell Rate
(PCR). This is the maximum rate at which the sender can send cells. Type the PCR here.This
field is not available when you select
UBR Without PCR
.
Sustainable Cell
Rate
The Sustainable Cell Rate (SCR) sets the average cell rate (long-term) that can be
transmitted. Type the SCR, which must be less than the PCR. Note that system default is 0
cells/sec.
This field is available only when you select
Non Realtime VBR
or
Realtime VBR
.
Maximum Burst
Size
Maximum Burst Size (MBS) refers to the maximum number of cells that can be sent at the
peak rate. Type the MBS, which is less than 65535.
This field is available only when you select
Non Realtime VBR
or
Realtime VBR
.

The 3G Backup Screen
The USB ports (at the left side panel of the Device) allow you to attach a 3G dongle to wirelessly
connect to a 3G network for Internet access. You can have the Device use the 3G WAN connection
as a backup. Disconnect the DSL and Ethernet WAN ports to use the 3G dongle as your primary
WAN connection. The Device automatically uses a wired WAN connection when available.
Note: This Device supports connecting one 3G dongle at a time.
