Naked DSL

A naked DSL, also known as standalone or dry loop DSL, is a digital subscriber line (DSL) without a PSTN (analogue telephony) service — or the associated dial tone. In other words, only a standalone DSL Internet service is provided on the local loop.

The original concept of DSL was to use existing telephone lines for high speed data communication, with DSL and telephone services coexisting on the same phone line - but increasingly customers may require only the Internet service - and see no need for the traditional phone service.
