| Parameter | Description |
| |
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. | ||
Encapsulation | Specifies how to handle multiple protocols at the | |||
|
| ATM transport layer. | ||
|
| • | ||
|
|
| ATM Virtual Circuit Multiplexer (null | |
|
|
| encapsulation) allows only one protocol | |
|
|
| running per virtual circuit with less | |
|
|
| overhead. | |
|
| • | LLC. Point to Point Protocol over ATM | |
|
|
| Logical Link Control allows multiple | |
|
|
| protocols running over one virtual circuit | |
|
|
| (uses slightly more overhead.) | |
Idle Time (Minute) | Enter the maximum idle time for the Internet | |||
|
| connection. After this time has been exceeded the | ||
|
| connection will be terminated. | ||
ISP Name | Choose the ISP to whom this connection will | |||
|
| apply. |
