Chapter 6 WAN Setup Table 14 Network > WAN > Internet Access Setup: Advanced Setup (continued) LABEL DESCRIPTION RIP Version This field is not configurable if you select None in the RIP Direction field. Multicast Select the RIP version from RIP-1, RIP-2B and RIP-2M. Multicast packets are sent to a group of computers on the LAN and are an alternative to unicast packets (packets sent to one computer) and broadcast packets (packets sent to every computer). Internet Group Multicast Protocol (IGMP) is a network-layer protocol used to establish membership in a multicast group. The P-793H v2 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-RT (real-time Variable Bit Rate) type for applications with bursty connections that require closely controlled delay and delay variation. Select VBR-nRT (non real-time Variable Bit Rate) type for connections that do not require closely controlled delay and delay variation. 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. PPPoE Passthrough (PPPoE encapsulation only) This field is available when you select PPPoE encapsulation. In addition to the P-793H v2's built-in PPPoE client, you can enable PPPoE pass through to allow up to ten hosts on the LAN to use PPPoE client software on their computers to connect to the ISP via the P793H v2. Each host can have a separate account and a public WAN IP address. PPPoE pass through is an alternative to NAT for application where NAT is not appropriate. MTU Disable PPPoE pass through if you do not need to allow hosts on the LAN to use PPPoE client software on their computers to connect to the ISP. 84 P-793H v2 User's Guide

RIP Version
This field is not configurable if you select
None
in the
RIP Direction
field.
Select the RIP version from
RIP-1
,
RIP-2B
and
RIP-2M
.
Multicast
Multicast packets are sent to a group of computers on the LAN and are
an alternative to unicast packets (packets sent to one computer) and
broadcast packets (packets sent to every computer).
Internet Group Multicast Protocol (IGMP) is a network-layer protocol
used to establish membership in a multicast group. The P-793H v2
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-RT
(real-time Variable Bit Rate) type for applications with bursty
connections that require closely controlled delay and delay variation.
Select
VBR-nRT
(non real-time Variable Bit Rate) type for
connections that do not require closely controlled delay and delay
variation.
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.
PPPoE
Passthrough
(PPPoE
encapsulation
only)
This field is available when you select
PPPoE
encapsulation.
In addition to the P-793H v2's built-in PPPoE client, you can enable
PPPoE pass through to allow up to ten hosts on the LAN to use PPPoE
client software on their computers to connect to the ISP via the P-
793H v2. Each host can have a separate account and a public WAN IP
address.
PPPoE pass through is an alternative to NAT for application where NAT
is not appropriate.
Disable PPPoE pass through if you do not need to allow hosts on the
LAN to use PPPoE client software on their computers to connect to the
ISP.
