Advanced Setup Method Parameter Description Protocol • Disable: Disables the connection. • 1483 Bridging: Bridging is a standardized layer 2 technology. It is typically used in corporate networks to extend the physical reach of a single LAN segment and increase the number of stations on a LAN without compromising performance. Bridged data is encapsulated using the RFC1483 protocol to enable data transport. Please note that setting the router to bridged mode disables all advanced features such as VoIP, Firewall, and QoS etc. • PPPoA: Point-to-Point Protocol over ATM is a method of encapsulating data for transmission to a far point. • 1483 Routing: 1483 Routing allows a simple, low-cost connection to the Internet via a standard Ethernet port. The router looks up the network address for each packet seen on the LAN port. If the address is listed in the routing table as local, it is filtered. If the address is listed under the ADSL port, it is forwarded. Or if the address is not found, then it is automatically forwarded to the default router (i.e. the VoIP Router at the head end). • PPPoE: Point-to-Point over Ethernet is a common connection method used for xDSL. • MAC Encapsulated Routing: If your ADSL service is a Bridged mode service and you want to share the connection to multiple PC's, please select MAC Encapsulated Routing. MER is a protocol that allows you do IP routing with NAT enabled. VPI/VCI Virtual Path Identifier (VPI) and Virtual Circuit Identifier (VCI). Data flows are broken up into fixed length cells, each of which contains a Virtual Path Identifier (VPI) that identifies the path between two nodes, and a Virtual Circuit Identifier (VCI) that identifies the data channel within that virtual path. Each virtual circuit maintains a constant flow of cells between the two end points. When there is no data to transmit, empty cells are sent. When data needs to be transmitted, it is immediately inserted into the cell flows. 28 Advanced Setup Method 1 Parameter Description Encapsulation 2 Shows the packet encapsulation type. Packet encapsulation specifies how to handle multiple protocols at the ATM transport layer. 3 • VC-MUX: Point-to-Point Protocol over ATM Virtual Circuit Multiplexer (null encapsulation) allows only one protocol running 4 per virtual circuit with less overhead. • LLC: Point-to-Point Protocol over ATM Logical Link Control allows 5 multiple protocols running over one virtual circuit (using slightly more overhead). 6 QoS Class 7 ATM QoS classes including CBR, UBR and VBR. PCR/SCR/MBS QoS Parameters - PCR (Peak Cell Rate), SCR (Sustainable Cell Rate) and MBS (Maximum Burst Size) are configurable. IP Address: If your IP address is assigned by the ISP each time you connect, leave this field all zeros. Otherwise, enter your ISP supplied static IP address here. Subnet Mask: If your subnet mask is assigned by the ISP each time you connect, leave this field all zeros. Otherwise, enter your subnet mask here. Connect Type Sets connection mode to always connected, automatic or manual connection. Idle Time: Enter the maximum idle time for the Internet connection. (in minutes) After this time has been exceeded the connection will be terminated. Username: Enter user name Password: Enter password Confirm Password: Confirm password MTU Leave the Maximum Transmission Unit (MTU) at the default value (1500) unless you have a particular reason to change it. 29 section
