On Step-by-Step exchanges in CT, 119X was the ringback (you got different rings depending on which digit you dialed last. 1192 gave you continuous ring, for example). On ESS and crossbar it was something else, I believe 99X-XXXX where XXXX was the last 4 digits of your number, and the X in 99X was an arbitrary check digit on a per prefix basis. My best friend had the best of me for years. He lived in Bethany which was crossbar, and all I had was step. Then we moved to Hamden and I got my very first ESS line (it was a #1ESS). CT has a package named Totalphone, which is speed-calling 8, call waiting, call forwarding, and 3-way calling. I won the feature-game with that one (smile).
