A teletypewriter is a kind of electric typewriter that can send a written message to another teletypewriter via a telephone line or via radio. The bell function caused a bell to ring to get the other operator's attention. This is old technology, I doubt any of these machines are used commercially today, they were replaced by the fax. These machines were noisy, as are some HP printers.
