Landline service is typically provided through the outside plant of a telephone company's central office, or wire center. The outside plant comprises tiers of cabling between distribution points in the exchange area, so that a single pair of copper wire, or an optical fiber, reaches each subscriber location, such as a home or office, at the network interface.
Often, the customer end of that wire pair is connected to a data access arrangement, and the telephone company end of that wire pair is connected to a telephone hybrid. In most cases, two copper wires (tip and ring) for each telephone line run from a home or other small building to a local telephone exchange.
A cell phone network intercom is an outdoor device that communicates wirelessly over the cell phone network with any landline or mobile phone worldwide.

The pair of wires from the central office switch to a subscriber's home is called a subscriber loop. It carries a direct current (DC) voltage at a nominal voltage of −48V when the receiver is on-hook, supplied by a power conversion system in the central office. This power conversion system is backed up with a bank of batteries, resulting in ...

In common-battery systems, the pair of wires from a subscriber's telephone to the exchange carry 48V (nominal) DC potential from the telephone company end across the conductors. The telephone presents an open circuit when it is on-hook or idle.
