Traditional telephone service, commonly known as a landline, operates independently of an internet connection. It uses physical copper wires to transmit voice signals directly to a telephone exchange, enabling voice communication. This fundamental functionality means that a digital network and its accompanying equipment are not required for basic telephone operation.
The enduring availability of this type of telephone service offers benefits such as reliability during power outages, as the line is often powered by the telephone company. Furthermore, in areas with limited or unreliable internet access, it provides a consistent means of communication, particularly in emergencies. Historically, it was the primary method of voice communication, and its infrastructure remains widespread, offering a familiar and established option for many.
