Interface Setup
 
Internet Settings
Internet :: ATM VC
ATM settings are used to connect to your ISP. Your ISP provides VPI, VCI settings to you. In this Device, you can totally setup 8 VCs on different encapsulations, if you apply 8 different virtual circuits from your ISP. You need to activate the VC to take effect. For PVCs management, you can use ATM QoS to setup each PVC traffic line's priority.
Virtual Circuit  Select the VC number you want to setup.
VPI Virtual Path Identifier.
VCI Vitrual Channel Identifier.
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.
SCR Sustained Cell Rate.
MBS Maximum Burst Size.
 
Internet :: Encapsulation
Dynamic IP  Select this option if your ISP provides you an IP address automatically. This option is typically used for Cable services. Please enter the Dynamic IP information accordingly.
Static IP  
Select this option to set static IP information. You will need to enter in the Connection type, IP address, subnet mask, and gateway address, provided to you by your ISP. Each IP address entered in the fields must be in the appropriate IP form, which is four IP octets separated by a dot (x.x.x.x). The Router will not accept the IP address if it is not in this format.
PPPoA/PPPoE Select this option if your ISP requires you to use a PPPoE connection. This option is typically used for DSL services. Select Dynamic PPPoE to obtain an IP address automatically for your PPPoE connection. Select Static PPPoE to use a static IP address for your PPPoE connection. Please enter the information accordingly.
Bridge Mode The modem can be configured to act as a bridging device between your LAN and your ISP. Bridges are devices that enable two or more networks to communicate as if they are two segments of the same physical LAN. Please set the Connection type.
 
Internet :: PPPoE/PPPoA
Select this option if your ISP requires you to use a PPPoE connection. This option is typically used for DSL services. Select Dynamic PPPoE to obtain an IP address automatically for your PPPoE connection. Select Static PPPoE to use a static IP address for your PPPoE connection. Please enter the information accordingly.
Username  Enter your username for your PPPoE/PPPoA connection.
Password  Enter your password for your PPPoE/PPPoA connection
Encapsulation For both PPPoE/PPPoA connection, you need to specify the type of Multiplexing, either LLC or VC Mux.
Connection Setting 
For PPPoE/PPPoA connection, you can select Always on or Connect on-demand. Connect on demand is dependent on the traffic. If there is no traffic (or Idle) for a pre-specified period of time), the connect will tear down automatically. And once there is traffic send or receive, the connection will be automatically on. Static/Dynamic IP Address For PPPoE/PPPoA connection, you need to specify the public IP address for this ADSL Router. The IP address can be either dynamically (via DHCP) or given IP address provide by your ISP. For Static IP, you need to specify the IP address, Subnet Mask and Gateway IP address.
 
Internet :: NAT
NAT Select this option to Activate/Deactivated the NAT (Network Address Translation) function for this VC. The NAT function can be activated or deactivated per PVC basis.
 
Internet :: Default Route
Default Route  if enable this function, the current PVC will be the default gateway to internet from this device.
 
Internet :: Dynamic Route
RIP (Routing Information protocol) Select this option to specify the RIP version, including RIP-1, RIP-2M and RIP-2B. RIP-2M and RIP-2B are both sent in RIP-2 format; the difference is that RIP-2M using Multicast and RIP-2 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. IN only means the ADLS router will only accept but will not send RIP packet. OUT only means the ADLS router will only send but will not accept RIP packet.
 
Internet :: Multicast
IGMP (Internet Group Multicast Protocol) is a session-layer protocol used to establish membership in a multicast group. The ADSL ATU-R supports both IGMP version 1 (IGMP-v1) and IGMP-v2. Select None to disable it.
 


LAN settings
These 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 private to your internal network and cannot be seen on the Internet.
 
LAN :: Dynamic Route
Please refer to Internet::Dynamic Route. The only difference is the interface.
 
LAN :: Multicast
Please refer to Internet::Multicast. The only difference is the interface.
 
LAN :: DHCP Server
DHCP stands for Dynamic Host Control Protocol. The DHCP Server gives out IP addresses when a device is booting up and request an IP address to be logged on to the network. That device 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 clients on the network.
Starting IP Address  The starting IP address for the DHCP server's IP assignment.
IP Pool Count The max user pool size.
Lease Time The length of time for the IP lease.
 
LAN :: 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 enable, 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.
 
LAN :: DNS Server
The DNS Configuration allows the user to set the configuration of DNS
DNS Relay selection If user want to disable this feature, he just need to set both Primary and secondary DNS IP to 0.0.0.0.Using DNS relay, users can setup DNS server IP to 192.168.1.1 on their Computer. If not, device will perform as no DNS relay.
