Who else sells DSL service?
In addition to incumbent telephone companies such as SBC, BellSouth, and US West, DSL is sold by Internet service providers, long-distance companies, and competitive local exchange carriers. Service providers such as Concentric Networks, EarthLink, WorldCom, Cyber Access, Flashcom, ShoreNet, and Verio offer DSL. For the most part, they resell DSL from wholesalers such as NorthPoint, Covad, incumbent telephone companies, and Rhythms. Some companies such as HarvardNet, Vittsm, and Digital Broadband sell DSL directly to end users without using wholesalers for the DSL modem and telephone company coordination. These service providers also install the DSL modem or modem/router if the end user needs Internet access for multiple computers. The router directs email and Web traffic to the appropriate computer. In addition to Internet access, all of these providers sell email, security software, and Web page hosting.
