Abstract :
DEVELOPMENT OF the coaxial system was started some time ago, with systems working before the war between New York, N. Y., and Philadelphia, Pa., and between Minneapolis, Minn., and Stevens Point, Wis. There are about 5,000 route miles in service providing almost three million miles of 2-way telephone circuits plus television network facilities. The entire program for the next few years roughly will triple the route miles and more than triple the circuit miles. Miami, Fla., now can talk over coaxial systems across the continent to Los Angeles, Calif., a distance of about 3,000 miles. It is also possible to talk from Albany, N. Y., to Charlotte, N. C., or from Buffalo, N. Y., to St. Louis, Mo., and by the middle of 1949, it will be possible to talk from New York to Los Angeles via Chicago over coaxials.
