Abstract

This paper discusses some principal results of a recent Bell System subscriber loop survey. Statistically sound estimates of various physical and transmission characteristics of the loop plant are presented. This information is useful in appraising the current transmission properties of the plant in the light of existing requirements. It provides a novel basis for evaluating new developments and services affecting present plant.
