Adding a New Connection
To conÞgure new Permanent Virtual Circuits (PVCs), enter the following information in the text Þelds which appear just below the connections list box:
1.In the I/F text box, click on the
2.In the VPI text box, enter the Virtual Path Identifier you wish to assign to this connection. Allowable values are 0 to 3; remember, the VPI you assign will be used to group virtual connections, allowing for channel trunking between ATM switches.
3.In the VCI text box, enter the Virtual Channel Identifier you wish to assign to this connection. Allowable values are 0 to 1023 for each VPI. For example, you could assign the same channel identifier — say, 25 — as many as four times: once with a VPI of 0, once with a VPI of 1, and so on. Again, remember that it is the combination of VPI and VCI that will be used to direct cells through the intermediate switches between the source and destination.
