Advanced Setup Method • LLC: Point-to-Point Protocol over ATM Logical Link Control (LLC) allows multiple protocols running over one virtual circuit (using slightly more overhead). Protocol: Protocol used for the connection ATM Interface Clicking on the ATM VC brings up the following screen. The VoIP Router uses ATM as its WAN interface. Protocols including 1483 Routing, 1483 Bridging, MAC Encapsulated Routing (MER), PPPoA and PPPoE with LLC-SNAP and VC-MUX encapsulations are supported for each ATM PVC. When you have finished entering your connection parameters, click "SAVE SETTINGS". You can verify that you have established an ADSL connection by clicking Status at the bottom of the left-hand menu. See below for a description of the parameters. 26 Advanced Setup Method 1 Parameter Description Protocol 2 • Disable: Disables the connection • 1483 Bridging: Bridging is a standardized layer 2 technology. It is typically used in corporate networks to extend the physical 3 reach of a single LAN segment and increase the number of stations on a LAN without compromising performance. Bridged 4 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 5 QoS etc • PPPoA: Point-to-Point Protocol over ATM is a method of 6 encapsulating data for transmission to a far point • 1483 Routing: 1483 Routing allows a simple, low-cost 7 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. 27 section
