LABEL DESCRIPTION
RIP Direction Select the RIP direction from None, Both, In Only and Out Only.
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 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.
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.
