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 Multicast 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 (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-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
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.
