I would like to find out where I can get detailed technical information on T1 communications lines. I am interested in everything from connector details and voltages, up to bit framing, scrambling and syncronizing. I want to know just what is needed if one is designing either the box that interfaced to the telco, or if one is designing the equipment telco is using (although the details of how they deal with it after it gets to them is not important). If there is a common interface device, I'd want to know the specs on each (telco and equipment) end. I am interesting in studying possible designs of devices than can emulate a T1 line.
