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

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
.
PPP Information (This is available only when you select
PPPoE
or
PPPoA
in the
Mode
field.)
PPP User Name
Enter the user name exactly as your ISP assigned. If assigned a name in the form
user@domain
where domain identifies a service name, then enter both components exactly
as given.
PPP Password
Enter the password associated with the user name above. Select
password unmask
to
show your entered password in plain text.
PPP Triger Type
Select when to have the Device establish the PPP connection.
Auto Connect
- select this to not let the connection time out.
Connect on Demand
- select this to automatically bring up the connection when the
Device receives packets destined for the Internet.
Manual
- select this if you want to
manually trigger the connection up.

encapsulation.
In addition to the Device’s built-in PPPoE client, you can enable PPPoE pass through to allow
up to ten hosts on the LAN to use PPPoE client software on their computers to connect to the
ISP via the Device. Each host can have a separate account and a public WAN IP address.
PPPoE pass through is an alternative to NAT for application where NAT is not appropriate.
Disable PPPoE pass through if you do not need to allow hosts on the LAN to use PPPoE client
software on their computers to connect to the ISP.
IP Address (This is available only when you select
IPv4 Only
or
IPv6/IPv4 DualStack
in the
IPv6/IPv4
Mode
field.)

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.

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.
