Virtual Path Identifier (VPI) refers to an 8-bit (user to network packets) or 12-bit (network-network packets) field within the header of an Asynchronous Transfer Mode packet. The VPI, together with the VCI (Virtual Channel Identifier) is used to identify the next destination of a cell as it passes through a series of ATM switches on its way to its destination. VPI is useful to reduce the switching table for some Virtual Circuits which have common path. In simple words these two numbers simply tell the DSL equipment on both the sides that the communication to be established between them.
VPI/ VCI settings are very much important to establish the connection between your Modem and Internet Service Providers. These settings varies from ISP to ISP. It is important that you should enter the correct VPI/VCI settings while configuring the MODEM. The VPI/VCI settings used by different ISPs at different countries are listed below:
