Words and sentences were sent over long wires in the form of short and long beeps.
Each letter was converted into a combination of dots (short beeps) and dashes (long beeps).
This was done by pressing a button on one side of the line.
On the other side of the line, these beeps sounded from a speaker, where the receiver deciphered them back into readable text.
