Configuration > WAN
Enter the name of your Internet Service Provider, e.g., MyISP. This information is
for identification purposes only.
Select Routing (default) from the drop-down list box if your ISP allows multiple
computers to share an Internet account. Otherwise select Bridge.
Select the method of encapsulation used by your ISP from the drop-down list box.
Choices vary depending on the mode you select in the Mode field.
If you select Bridge in the Mode field, select either PPPoA or RFC 1483.
If you select Routing in the Mode field, select PPPoA, RFC 1483, ENET ENCAP
or PPPoE.
Select the method of multiplexing used by your ISP from the drop-down list.
Choices are VC or LLC.
VPI (Virtual Path Identifier) and VCI (Virtual Channel Identifier) define a virtual
circuit. Refer to the appendix for more information.
The valid range for the VPI is 0 to 255. Enter the VPI assigned to you.
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.
Select CBR (Continuous 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 configuration often helps eliminate traffic congestion that slows
transmission of real time data such as audio and video connections.
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.
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 (MBS) refers to the maximum number of cells that can be
sent at the peak rate. Type the MBS, which is less than 65535.
(PPPoA and PPPoE encapsulation only)
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.
