telegraph service
Morse code network
Telegraph service is the system for sending and receiving telegrams—messages transmitted electrically over wires using coded signals.
Before telephones and the internet, telegraph service was the fastest way to communicate over long distances: We sent word by telegraph service that the ship had arrived safely.
The service typically charged by the word, encouraging brevity.
