Dry loop allows you to use DSL over a dormant phone line (a phone line without active telephone service). A dry loop essentially re-activates the line so that a DSL signal can pass over it, but does not enable you to make or receive calls.
Dry loop is required when:
- You do not have active analog phone service.
- You use VoIP phone service.
- You use phone service provided by a cable carrier (these services use your cable lines instead of your phone lines to provide service)
Dry Loop and Wet Loop have no difference in terms of speed or quality of service. It is simply a way to bring the signal to your home.
