    z ATM VC 
     
    Parameter Description 
    Virtual Circuit  VPI (Virtual Path Identifier) and VCI (Virtual Channel 
    Identifier define a virtual circuit. 
      
    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. 
     
     
      
    						
    							 25
    Parameter Description 
    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.
      
      
    ATM QoS  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.  
     
    UBR (Unspecified Bit Rate) – Select UBR for applications 
    that are non-time sensitive, such as e-mail. 
     
    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. 
     
    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. 
    Statistical multiplexing is provided to make optimum use 
    of network resources. Multimedia e-mail is an example of
     nrtVBR. 
      
    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. 
      
    SCR  SCR (Sustain Cell Rate) is the average rate, as 
    measured over a long interval, in the order of the 
    connection lifetime.  
    						
    							 26
    Parameter Description 
    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.

    NAT  NAT (Network Address Translation), an Internet standard 
    that enables a local-area network (LAN) to use one set of 
    IP addresses for internal traffic and a second set of 
    addresses for external traffic. When NAT is enabled, the 
    router will help to make all necessary IP address 
    translations for the PC connected to the router to access 
    the Internet. 
      
    Default Route  When “Default Router” is enabled, all the packets for 
    destinations not known by the routers routing table are 
    sent to the default route.  By default, it is enabled. 
      
    TCP MTU Option  MTU (Maximum Transmission Unit) determine the 
    maximum size of each packet in any transmission within 
    the network. Please specify the MTU range from 100 to 
    1500 bytes or 0 byte as the default value.  
      
    Dynamic Route  Dynamic routing allows routing tables in routers to 
    change as the possible routes change. This router 
    supports RIP1, RIP2-B and RIP2-M protocols for 
    dynamic routing. After the RIP protocol is selected, 
    please choose the RIP direction from “None”, “Both”, “IN 
    Only” or “OUT Only”.

    many receivers.  Please select “IGMP v1” or “IGMP v2”
    as the multicast protocol or select “Disabled” to disable 
    the function. 
      
    IGMP Snoop  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 in the network 
    and degrade the performance of the network. 
     
     
    z DHCP 
     
    Parameter Description 
    DHCP  You can enable or disable the DHCP server. By enabling 
    the DHCP server the router will automatically give your 
    LAN clients an IP address. If the DHCP is not enabled 
    then you’ll have to manually set your LAN client’s IP 
    addresses. 
      
    Starting IP Address  If the DHCP Server is enabled, please set the “Starting  
    						
    							 31 IP Address” which will be the first IP Address assigned to 
    the LAN client. By default, the “Starting IP Address” is 
    192.168.2.100. 
      
    IP Pool Count  You can select a particular IP address range for your 
    DHCP server to issue IP addresses to your LAN Clients. 
    By default, the “IP Pool Count” is 100. The IP range is  
    starting from IP 192.168.2.100 to 192.168.2.199. 
     
     
    Parameter Description 
    Lease Time  In the Lease Time setting you can specify the time period 
    that the DHCP Server lends an IP address to your LAN 
    clients. The DHCP will change your LAN client’s IP 
    address when this time threshold period is terminated. 
      
    DNS Relay  A Domain Name System (DNS) server is like an index of 
    IP addresses and Web addresses. If you type a Web 
    address into your browser, such as “www.router.com”, a 
    DNS server will find that name in its index and the 
    matching IP address. Please select “Use Auto 
    Discovered DNS Server Only” to auto set the DNS 
    Server. If there is a DNS server that you would rather to 
    use, please select “Use Discovered DNS Server Only”
    and you need to specify the IP address of that DNS 
    server.
