Figure 47 More Connections Advanced Setup Chapter 5 WAN Setup The following table describes the labels in this screen. Table 25 More Connections Advanced Setup LABEL DESCRIPTION RIP & Multicast Setup RIP Direction Select the RIP direction from None, Both, In Only and Out Only. RIP Version Select the RIP version from RIP-1, RIP-2B and RIP-2M. Multicast IGMP (Internet Group Management Protocol) is a network-layer protocol used to establish membership in a multicast group. The ZyXEL Device supports both IGMP version 1 (IGMP-v1) and IGMP-v2. Select None to disable it. ATM QoS 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-nRT (Variable Bit Rate-non Real Time) or VBR-RT (Variable Bit Rate-Real Time) for bursty traffic and bandwidth sharing with other applications. 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 Maximum Burst Size (MBS) refers to the maximum number of cells that can be Size sent at the peak rate. Type the MBS, which is less than 65535.
