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).

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]}
