About the UAX  project

The UAX project is my personal attempt to try and get information of GPO Unit Automatic Exchanges available to all. I hope that in time it will be THE place to find information on these telephone exchange, in much the same way that Bob's Telephone File is the place to look for subscribers telephone equipment. I will be adding information to the pages as I can, so over a period of time the site will grow. If you have any information that you think will be of interest to me, so that I can add it to the site please feel free to email me.
