5-6 WAN
Table 5-1 WAN Setup
LABEL DESCRIPTION
Name Enter the name of your Internet Service Provider, e.g., MyISP. This information is for
identification purposes only.
Mode
Select Routing (default) from the drop-down list box if your ISP allows multiple
computers to share an Internet account. Otherwise select Bridge.
Encapsulation 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.
Multiplex Select the method of multiplexing used by your ISP from the drop-down list. Choices
are VC or LLC.
Virtual Circuit ID VPI (Virtual Path Identifier) and VCI (Virtual Channel Identifier) define a virtual circuit.
Refer to the appendix for more information.
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.
ATM QoS Type
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.
VBR is not available on all models.
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.
