Add an ATM Layer 2 Interface
1. In the left hand menu pane, click Advanced Setup.
2. Under Advanced Setup, click Layer2 Interface then ATM Interface, then click the Add
button.
3. In the VPI and VCI text boxes enter appropriate VPI/VCI numbers.
VPI/VCI (Virtual Path Identifier/Virtual Circuit Identifier) values essentially define the “pipe”
which sends data from the upstream device to the gateway. The VPI/VCI values will be
given to you by your ISP.
4. In the DSL Latency field, select Fast and/or Interleaved.
Use the default settings. Only change to increase precedence if the interface is dedicated
for video or voice applications.
