A landline[a] is a telephone connection that uses metal wires from the owner's premises also referred to as: POTS, Twisted pair, telephone line or public switched telephone network (PSTN).
Landline services are traditionally provided via an analogue copper wire to a telephone exchange. Landline service is usually distinguished from other more modern forms of telephone services which use Internet Protocol based services over optical fiber (Fiber-to-the-x) or other broadband services (VDSL/Cable) using Voice over IP, although sometimes modern fixed phone services delivered over a fixed internet connection are sometimes referred to as a landline (non-cellular service).[1]
