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. |
| • | PPPoA: |
|
| 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 Modem 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 |
|
| Modem (i.e., the Modem at the head end). |
| • | PPPoE: |
|
| 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 | See 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. | |
