Parameter Description
The parameters are described as below:
VPI (Virtual Path Identifier): Identifies the virtual path between endpoints in an ATM network. The valid range is
from 0 to 255.
VCI (Virtual Channel Identifier): Identifies the virtual channel endpoints in an ATM network. The valid range is
from 32 to 4095 (1 to 31 is reserved for well-known protocols).
ATM Service Type: Currently, the ADSL Router supports the UBR (Unspecified Bit Rate) service type.
PCR (Peak Cell Rate): Specify the PCR cells per second.
Encapsulation Type: There are two types for your choosing, VC MUX or LLC/SNAP. Select the encapsulation
based on the setting of the ISP. Consult your ISP for this information.
Local WAN IP Address: On Router mode, selecting None means you have public LAN IP address setting. If you
select Specify an IP address, you can specify a WAN IP provided by ISP for your router. If
Server assigned IP address is selected, the router will get a dynamic WAN IP address
whenever it connects to the remote server or ISP.
Note: If a fixed WAN IP is entered, note that this IP address and the subnet mask could not
be the same with the public LAN interface.
Enable NAT on this interface: If your LAN interface is set on primary LAN you should check the box of the Enable
Network Address Translation. NAT translates a private IP within one network to a public IP
address.
User Name/Password: The user name and password used to access the remote server or ISP.
