The basic principle of the telephone
0 komentarKetika gagang telepon diangkat, posisi telepon disebut off hook. Lalu sirkuit terbagi menjadi dua jalur di mana bagian positifnya akan berfungsi sebagai Tip yang menunjukkan angka nol sedangkan pada bagian negatif akan berfungsi sebagai Ring yang menunjukkan angka -48V DC. Kedua jalur ini yang nantinya akan memproses pesan dari sender untuk sampai ke receiver. Agar dapat menghasilkan suara pada telepon, sinyal elektrik ditransmisikan melalui kabel telepon yang kemudian diubah menjadi sinyal yang dapat didengar oleh telepon receiver. Untuk teknologi analog, transmisi sinyal analog yang dikirimkan dari central office (CO) akan diubah menjadi transmisi digital. Angka-angka sebagai nomer telepon merupakan penggabungan antara nada-nada dan frekuensitertentu yang kemudian dinamakan Dual-tone multi-frequency DTMF dan memiliki satuan Hertz. Hubungan utama yang ada dalam sirkuit akan menjadi on hook ketika dibuka, lalu akan muncul getaran. Bunyi yang muncul di telepon penerima menandakan telepon telah siap digunakan.
