A 80+ year-old ringing and tone supply concept. This was used by automatic, electric, ITT and western electric to a certain degree. I included this as a bonus video of my AE Stroger system. I was unsure if these items were going to be operational when I was wiring up the main part of the AE step. This is just a bonus video. Enjoy like subscribe and share.
