The Evolution of Accessible Telecommunication: A Timeline of TDI’s Impact
What are the TDI Agents?
They are the ones responsible for installing the TTYs and training individuals and businesses how to use them. They also sell TDI memberships.
Most of them were men who liked to tinker with the intricate mechanical parts inside the TTY. If they have wives, they will help them by testing the new TTY and to see if they keys are working properly. TDI credited them as “the nuts and bolts of TDI” since they helped TDI hold together at the outset.
In 1968, the Hoosier State Telephone Pioneers trained an army of TDI agents to repair and restore donated TTYs so they can be distributed to customers across the US.
In 1974, TDI published Teletypewriters Made Easy, a pictorial TTY repair manual for TDI Agents. It shows photos and instructions for troubleshooting a broken TTY and making the appropriate repairs. The agents believed this manual was a very useful tool.
Actually, if not for them, then the deaf telephone network would not have grown that much in the 70’s, 80’s, and 90’s.
