What are VCI/VPI, what do I enter ?
The most important information to enter to get a DSL modem working is the Virtual Path Identifier (VPI) and Virtual Circuit Identifier (VCI) . These two numbers simply tell the DSL equipment on both ends that they should talk to each other, almost the same as replacing a dialed number. Each DSL provider uses a set of these two numbers.
For a list of known VCI/VPI values, please see this article.
Please note that some ISP's (Earthlink, Mindspring, Speakeasy, etc.) may use your local telco for the network services. In such cases, just use the VPI/VCI values for your telco/CLEC.
