I can answer questions regarding land line phone systems, wiring methods, troubleshooting, as well as restoration of antique phones. (1900's to 1980's) I am still learning about newer technologies like VOIP and other digital modes, but may still be able to help with these topics from time to time.
I have collected antique telephones since I was a teen, and been involved in wiring of home phone lines, as well as troubleshooting problems with them since around the same time.
I have studied basic electrical fundamentals through classes in a technical college, as well as extensive reading on the subject in my own time. I have also helped Electricians and telecom installers on and off for some time.
