Application of the Type-P1 carrier system to rural telephone lines

摘要

THE rural service situation is one of the most pressing and difficult problems to solve in the telephone industry. The use of fixed outside plant such as cable, open wire, or B rural wire (6-pair distribution wire or cable) proves expensive in many instances for providing each customer in the rural area with the grade of service he desires when he wants it. This is particularly true for rural areas because of the difficulty of accurately forecasting rural service demands.
