Landline Phone

Landline phones, also known as fixed-line telephones, are devices used for voice communication through a network of physical wires or cables. Despite the rise of mobile phones and digital communication methods, landline phones continue to be an important mode of communication in many households and businesses due to their reliability and consistent call quality.

  • Connection to Network: Landline phones are connected to the public switched telephone network (PSTN) via a physical line, typically a pair of copper wires.
  • Dialing and Signaling: When a number is dialed, the phone sends a signal to the local exchange, which then routes the call through a series of switches to connect to the recipient's phone.
  • Transmission: Voice signals are converted into electrical signals, transmitted over the network, and then converted back into sound by the receiving phone.
  • Power Supply: Landline phones receive power from the telephone line, which allows them to function even during power outages, unlike most cordless or mobile phones.
