Chapter 5 Device Network Settings Table 29 Device Operation > Device Configuration > Network > WAN > Setup (Prestige) (continued) LABEL DESCRIPTION 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 (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 email. 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 (longterm) 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. 104 Vantage CNM User's Guide
