Definition
The combined forces of deregulation and broadband local-loop technologies such as digital subscriber line (DSL) have created unprecedented opportunities for service providers of all types to maximize their revenues by offering new and exciting services. One of the greatest of these opportunities is presented by voice over DSL (VoDSL) technology.
