Dry loop
A dry loop (also known as a dry pair) is an unconditioned leased pair of telephone wire from a telco. The pair does not have a dial-tone or "battery" (continuous electric potential), as opposed to a "wet pair" (a line usually with no dial tone but with battery).
A dry pair was originally used with a security system, but more recently may also be used with DSL equipment [1] or an Ethernet extender to connect two locations, as opposed to a costlier means such as frame relay. The pair in many cases goes through the local central office.
Many carriers market dry loops to independent DSL providers, as a BANA for basic analog loop or in some locales PANA for plain analog loop, OPX (off-premise extension) line, paging circuit, or finally LADS (local area data service).
[edit] Local availability
In the United States, these circuits typically incur a monthly recurring charge (MRC) of $3.00 per 1/4 mile (approximately), plus an additional handling fee of around ($5–10).[citation needed]
In Canada, since the CRTC ruling of 21 July 2003, it should be theoretically possible to have Dry loop and some companies do provide this service. There is not yet widespread adoption, due largely to a lack of consumer awareness, Naked ADSL is currently provided by MySignal.ca Inc., in the provinces of Ontario and Quebec, Bell Canada charges an additional fee for dryloop based on the Band Rate of the area.
