Abstract :
Considerable development work on carrier in cable has included an extensive installation on a 25-mile loop of underground cable. Sufficient pairs were provided in the cable and repeaters installed to set up 9 carrier telephone circuits 850 miles long. Tests showed transmission quality to be satisfactory, and adequate prevention of interference was secured. The obtaining of large numbers of carrier telephone circuits from cable was proved to be practicable.
