Yes!! To the death!!! A goddamn ringing sound... β162.158.91.165 (talk) (please sign your comments with ~~~~)
In the olden days of electro-mechanical telephone exchanges, each exchange would have a 17 Hz ring tone generator. When a call was switched through, it would send a 17 Hz signal down the line which would be picked off by a 17 Hz pick-off filter in the receiver. This would then activate the bell inside the receiver, causing it to ring. (Feel free to delete if deemed irrelevant). -- The Cat Lady (talk) 10:56, 15 August 2021 (UTC)
