ATM QoS Type Select CBR (Constant Bit Rate) to specify fixed (always-on) bandwidth for
voice or data traffic. Select UBR (Unspecified Bit Rate) for applications
that are non-time sensitive, such as e-mail. Select VBR (Variable Bit Rate)
for bursty traffic and bandwidth sharing with other applications.
Cell Rate Cell rate configuration often helps eliminate traffic congestion that slows
transmission of real time data such as audio and video connections.
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.
Sustain Cell Rate The Sustain 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.
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.
Login Information (PPPoA and PPPoE encapsulation only)
Service Name
(Appears when you use
PPPoE encapsulation)
This field is only available when PPPoE encapsulation is selected. Type
the PPPoE service name provided to you. PPPoE uses a service name to
identify and reach the PPPoE server.
PPPoE +
PPPoE_Client_PC
(Appears when you use
PPPoE encapsulation)
This field is only available when PPPoE encapsulation is selected.
Select the check box to enable PPPoE pass through. 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.
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.
Password Enter the password associated with the user name above.
IP Address This option is available if you select Routing in the 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. The Single User Account feature can be used with
either a dynamic or static IP address.
Select Obtain an IP Address Automatically if you have a dynamic IP
address; otherwise select Static IP Address and type your ISP assigned
IP address in the IP Address field below.
Connection
(Appears when you use
PPPoA and PPPoE
encapsulation)
The schedule rule(s) in SMT menu 26 have priority over your
Connection settings.
Nailed-Up Connection
(Appears when you use
PPPoA and PPPoE
encapsulation)
Select Nailed-Up Connection when you want your connection up all the
time. The device will try to bring up the connection automatically if it is
disconnected.
Connect on Demand
(Appears when you use
PPPoA and PPPoE
encapsulation)
Select Connect on Demand when you don't want the connection up all
the time and specify an idle time-out in the Max Idle Timeout field.
