I suspect my colleagues think I'm a little bonkers. I take delight in doing clean-up work in our wiki, and fleshing it out to be an increasingly useful tool for our students, prospective customers, and anyone else that finds it useful. Today I happened upon our page about the central office switch and it seemed to me it needed a bit of fleshing out. Once I had done that, it just seemed natural to record a PodSnack about this key device in the PSTN that has seen so many changes over the life of the voice network. I hope you enjoy today's installment.
