Summary : A discussion of telephone systems from the earliest rotary dial to the modern digital systems. The many differences between Numbering Zone One and the rest of the world. Some of the serious mistakes made in the development of the modern network and likely future problems. Security of networks, scams, politics, and extreme disparities in quality of service and rates charged. Old and modern switching, signaling, and transmission technology. A live demonstration and explanation of the sounds of certain switches and how to identify them. With luck, we'll find some of the earliest equipment still in service and allow the audience to hear if technically possible. An attempt is being made to find recordings and pictures of old systems though these are extremely rare. We welcome any contributions of pictures and/or recordings.
