Parameter Description 
VPI 
 VPI is a virtual path determines the way an ATM cell 
should be routed. The VPI is an 8-bit (in UNI) or 12-bit (in 
NNI) number that is included in the header of an ATM 
cell. The valid range for the VPI is 0 to 255. Enter the VPI 
assigned by the ISP. 
  
VCI  VCI is the label given to an ATM VC to identify it and 
determine its destination. The VCI is a 16-bit number that 
is included in the header of an ATM cell. The valid range 
for the VCI is 32 to 65535. Enter the VCI assigned by the 
ISP.
  
  
QoS UBR (Unspecified Bit Rate) – Select UBR for 
applications that are non-time sensitive, such as e-mail. 
 
CBR (Constant Bit Rate) – This class is used for 
emulating circuit switching. The cell rate is constant with 
time. Select CBR to specify fixed (always on) bandwidth 
for voice or data traffic.  
 
nrtVBR (non-real time Variable Bit Rate) – This class 
allows users to send traffic at a rate that varies with time 
depending on the availability of user information.  
						

							 34 Statistical multiplexing is provided to make optimum use 
of network resources. Multimedia e-mail is an example of 
nrtVBR. 
 
rtVBR (real time Variable Bit Rate) – This class is 
similar to nrtVBR but is designed for applications that are 
sensitive to cell-delay variation. Examples for real-time 
VBR are voice with speech activity detection (SAD) and 
interactive compressed video. 
  
PCR  Divide the DSL line rate (bps) by 424 (the size of an ATM 
cell) to find the PCR (Peak Cell Rate). This is the 
maximum rate at which the sender can send cells. 
  
CDVT  PCR generally is coupled with the CDVT (Cell Delay 
Variation Tolerance), which indicates how much jitter is 
allowable. 
  
SCR  SCR (Sustain Cell Rate) is the average rate, as 
measured over a long interval, in the order of the 
connection lifetime. 
  
MBS  MBS (Maximum Burst Size) refers to the maximum 
number of cells that can be sent at the peak rate. Type 
the MBS, which is less than 65535.

matching IP address. This page is used to select the way to obtain the IP 
addresses of the DNS servers.

							 39 5.2.2.6. RIP 
 
RIP is an Internet protocol you can set up to share routing table information 
with other routing devices on your LAN, at your ISP’s location, or on remote 
networks connected to your network via the ADSL line. 
 
Most small home or office networks do not need to use RIP; they have only 
one router, such as the ADSL Router, and one path to an ISP. In these cases, 
there is no need to share routes, because all Internet data from the network is 
sent to the same ISP gateway. 
 
You may want to configure RIP if any of the following circumstances apply to 
your network: 
z Your home network setup includes an additional router or RIP-enabled PC 
(other than the ADSL Router). The ADSL Router and the router will need 
to communicate via RIP to share their routing tables. 
z Your network connects via the ADSL line to a remote network, such as a 
corporate network. In order for your LAN to learn the routes used within 
your corporate network, they should both be configured with RIP. 
z Your ISP requests that you run RIP for communication with devices on 
their network. 
 
  
						

							 40 
Parameter Description 
RIP Enable/disable the RIP feature.  
 
Interface  Select the interface that you want to enable the RIP 
feature. 
  
Receive Mode Indicate the RIP version in which information must be 
passed to the DSL device in order for it to be accepted 
into its routing table. 
  
Send Mode  Indicate the RIP version this interface will use when it 
sends its route information to other devices. 
  
RIP Config Table  The RIP you have configured will be listed in the table. If 
you want to delete some settings, please select the 
settings and click “Delete Selected”. 
When you finish, click ‘Apply Changes’. You’ll see the following message 
displayed on web browser:

5.2.3. LAN 
 
This page is used to configure the LAN interface of your ADSL Router. You 
can set IP address, subnet mask, and IGMP Snooping. 
 
 
 
Parameter Description 
Interface Name  The interface name is “br0”. 
  
IP Address 
 Enter the IP Address of the ADSL router for the local user to 
access the router’s web page. By default, the IP Address is 
192.168.1.1. 
  
Subnet Mask  Enter the Subnet Mask of the ADSL router. By default, the 
Subnet Mask is 255.255.255.0. 
  
Secondary IP  Assign second IP address to LAN. 
  
IGMP Snooping  Enable/disable the IGMP snooping function for the multiple 
bridged LAN ports. When “IGMP Snoop” (Internet Group 
Management Protocol Snoop) is enabled, the router can make 
intelligent multicast forwarding decisions by examining the 
contents of each frame’s IP header. Without the function, the 
router will broadcast the multicast packets to each port and 
may create excessive traffic on the network and degrade the  
						

							 42 performance of the network. 
  
Ethernet to 
Wireless 
Blocking Enable/disable the ‘Ethernet to Wireless Blocking’, when this 
function is enabled, the traffic between Ethernet and wireless 
interfaces is not allowed. 
When you finish, click ‘Apply Changes’. You’ll see the following message 
displayed on web browser: 
 
 
 
Press ‘Continue’ to save the settings made and back to web management 
interface; press ‘Apply’ to save the settings made and restart the router so the 
settings will take effect after it reboots. 
 
 
5.2.3.1. DHCP  Mode 
 
You can configure your network and the router to use the Dynamic Host 
Configuration Protocol (DHCP). This page allows you to select the DHCP 
mode that this router will support. 
 
There are two different DHCP Modes: DHCP Serve and DHCP Relay. When 
the router is acting as DHCP server, please configure the router in the “DHCP 
Server” page; while acting as DHCP Relay, you can setup the relay in the 
“DHCP Relay” page.
