copper line
Metallic plumbing tube
A copper line is a telecommunications wire made of copper, particularly the traditional telephone cables that carried voice signals before fiber optics and wireless technology.
The term often appears in discussions of aging infrastructure: They're finally replacing the old copper lines with fiber.
Copper lines also refer to copper plumbing pipes that carry water.
