T. C. Ballister
editThomas C. Ballister, (Tom), was a Member of Technical Staff at Bell Telephone Laboratories from 1976 until 1984. He was a Member of Technical Staff (MTS) in the T1 Systems Engineering Group under J. R. Davis at the Bell Laboratories Holmdel, NJ facility. He was involved in an extensive characterization of the T1 Transmission System which had the high level goal of establishing the amount of error margin that existed within the deployed operating company plant. Much of this work was foundational to the subsequent research and development of more sophisticated modulation and encoding techniques that resulted in Integrated Services Digital Network (ISDN) technologies, and later into Digital Subscriber Line (DSL) technologies. His colleagues at Bell Laboratories were gracious enough to invite him to contribute to several co-authored articles reporting on their findings in the Bell System Technical Journal, July-August, 1981, Vol 60, No. 6, Part 1. [At that time his family name was "Kaup" his step father's, and he is published under the name "T. C. Kaup". After his step-father's death he legally resorted to his birth name of Ballister].
