dry copper pair Also known as a burglar alarm circuit. A twisted pair that is not electrified, that is, has no associated electronics. Providers of digital subscriber line (DSL) services and burglar alarm services order dry copper pairs from the telco and place their own electronics on them. All they want is a pair of wires from one point to another. See also dark fiber, dry, twisted pair, and xDSL. |
