Item Description

THE LOOP PLANT -- Part I - Loop Plant Modeling; Part II - Loop Plant Electronics. Whole issue devoted to this subject.

'The following ten papers describe various models of the telephone loop plant. The papers cover work done chiefly during the previous decade, although the foundations of the work are often much older. The loop plant, which is described in detail in Section II of this overview, is a fruitful area for operations modeling... The loop plant is the part of the telephone network connecting the customer to the nearest switching office. As used here, Loop Plant covers both the physical network, and the activities required to operate it...' (from the introduction, overview)
