[edit] Help with references please

I noticed this article sitting as an uncompleted link, and wrote the description from memory. I worked on the GTD-5 from 1980 until 1997, and was one of the engineers present at original cutover. I have not had any luck finding quotable reference material for the information contained herein. If anyone has copies of the old Automatic Electric Journal, it would help.

Wow. This is an excellent article. I wish I knew so much for the 1ESS switch and Panel switch articles I wrote. Jim.henderson 20:59, 15 April 2007 (UTC)

The tense of this article needs to be changed to present tense. This switch is actively being used in various areas of the US and is a current telecommunications solution. Thanks! Gzylks 21:57, 22 August 2007 (UTC)
