VCI
: Virtual Channel Identifier. The valid range for the VCI is 1 to 65635 (0 to 31 is reserved for local
management of ATM traffic).
ATM QoS:
Select the Quality of Service types for this Virtual Circuit. The ATM QoS types include
CBR(Constant Bit Rate), VBR(Variable Bit Rate) and UBR (Unspecified Bit Rate). These QoS types
are all controlled by the parameters specified below, including PCR, SCR, and MBS.
PCR:
Peak Cell Rate (PCR) is the maximum rate at which the sender can send cells. This parameter
may be lower (but not higher) than the maximum line speed. 1 ATM cell is 53 bytes (424 bits), so a
maximum speed of 832 Kbps gives a maximum PCR of 1962 cells/sec. This rate is not guaranteed
because it is dependent on the line speed.
SCR:
Sustained Cell Rate (SCR) is the mean cell rate of a bursty, on-off traffic source that can be sent
at the peak rate, and a parameter for burst-type traffic. SCR may not be greater than the PCR; the
system default is 0 cells/sec.
MBS:
Maximum Burst Size (MBS) is the maximum number of cells that can be sent at the PCR. After
MBS is reached, cell rates fall below SCR until cell rate averages to the SCR again. At this time, more
cells (up to the MBS) can be sent at the PCR again.
CBR
is for connections that support constant rates of data transfer. The only parameter you need to
worry about in CBR is PCR.
UBR
is for connections that have variable traffic. The only parameter you need to worry about in UBR
is PCR.
rtVBR
is for connections that, while having variable traffic, require precise timing between traffic
source and destination. PCR, SCR and MBS must all be set for rtVBR.
nrtVBR
is for connections that have variable traffic, do not require precise timing, but still require a
set bandwidth availability. PCR, SCR and MBS must all be set for nrtVBR.

using Multicast and RIP2-B using Broadcast format.
RIP Direction:
Select this option to specify the RIP direction.
None
is for disabling the RIP function.
Both
means the ADSL Router will periodically send routing information and accept routing
information then incorporate into routing table.

will not send RIP packet.
OUT only
means the ADSL router will only sent but will not accept RIP
packet.

5.2 LAN
There are the IP settings of the
LAN
Interface for the device. These settings may be referred to as
Private settings. You may change the LAN IP address if needed. The LAN IP address is provided to
your internal network and cannot be seen on the Internet.
5.2.1 Router Local IP
IP Address:
Enter the IP address of your ADSL router in dotted decimal notation, for example,
192.168.1.1 (default setting).
IP Subnet Mask:
Your ADSL router will automatically calculate the subnet mask based on the IP
address that you assign. Unless you are implementing sub netting, use the subnet mask computed
by the ADSL router.
Dynamic Route:
Select the Dynamic Route from
RIP1
,
RIP2-B
, and

IGMP Snoop:
You can disable and enable IGMP Snoop function.
5.2.2 Explaining RIP Setup
Routing Information Protocol (RIP) allows a router to exchange routing information with
other routers. The RIP Direction field controls how RIP packets are allowed to enter and leave the
router. Selecting
Both
means the router will broadcast its routing table and incorporate the RIP
information that it receives. Selecting
In Only
means the router will
only
accept
RIP
packets
received, not send RIP packets. Selecting
Out Only
means the router will only send RIP packets, not
accept any RIP packets received. Selecting
None
means the router will not send any RIP packets nor
will it accept any RIP packets received.TheDynamic Route field controls the format and the
broadcasting method of RIP packets that the router sends. It recognizes both formats when receiving
packets.
RIP-1
is universally supported, but
RIP-2
carries more information.
RIP-1
is adequate for
most networks. Only consider
RIP-2
if your network has unusual topology.Both
RIP-2B
and
RIP-2M
sends the routing data in
RIP-2
format.
RIP-2B
uses subnet
broadcasting
while
RIP-2M
uses multicasting.

5.2.3 DHCP Server
The DHCP Server gives out IP addresses when a device is booting up and request an IP to be
logged on to the network. It must be set as a DHCP client to obtain the IP address automatically.
By default, the DHCP Server is enabled. The DHCP address pool contains the range of the IP
address that will automatically be assigned to the client on the network.
LABEL
DESCRIPTION
Starting IP Address
Enter the starting IP address you wish to use as the DHCP server's IP
assignment.
IP Pool Count
Enter the maximum user pool size you wish to allow.
Lease Time
Enter the amount of time you wish to lease out a given IP address.
DNS Relay
Select the DNS relay option you wish to use from the dropdown list.
Primary DNS Server
Enter the primary DNS server IP address you wish to use. For user discovered
DNS only.
Secondary DNS Server
Enter the secondary DNS server IP address you wish to use. For user
discovered DNS only.
5.2.4 DHCP Relay
A DHCP relay is a computer that forwards DHCP data between computers that request IP
addresses and the DHCP server that assigns the addresses. Each of the device’s interfaces can be
configured as a DHCP relay. If it is enabled, the DHCP requests from local PCs will forward to the
DHCP server runs on WAN side. To have this function working properly, please run on router
mode only, disable the DHCP server on the LAN port, and make sure the routing table has the
correct routing entry.
DHCP Server IP for relay agent:
The DHCP server IP Address runs on WAN side.
