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 P-660HWP-Dx 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.
