RIP & Multicast Setup This section is not available when you configure the P-660H-T1v3s 

to be in bridge mode.

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-660H-T1v3s supports IGMP-v1, IGMP-v2 and IGMP-v3. 
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.
