Telepon Kawat

Telepon kabel adalah mikrofon (pemancar) untuk berbicara dan earphone (penerima) yang mereproduksi suara di lokasi yang jauh. Selain itu, sebagian besar telepon memiliki dering untuk mengumumkan panggilan telepon masuk, dan dial atau papan tombol untuk memasukkan nomor telepon saat melakukan panggilan ke telepon lain. Penerima dan pemancar biasanya dibangun ke dalam sebuah handset yang diangkat ke telinga dan mulut selama percakapan. Dial mungkin terletak di handset atau di unit dasar yang terhubung dengan handset. Pemancar mengubah gelombang suara menjadi sinyal listrik yang dikirim melalui jaringan telepon ke telepon penerima, yang mengubah sinyal menjadi suara yang dapat didengar di penerima atau kadang-kadang pengeras suara. Telepon adalah perangkat dupleks, artinya memungkinkan transmisi di kedua arah secara bersamaan.
