My Dad retired out of Southwestern Bell here in Oklahoma and he has worked on many steppers. Then he replaced them with the Northern Telecom systems.

I heard MF tones in the background around 45:37 does anyone know what is happening there? Ive been to this museum multiple times and never heard any MF tones before.
