Type-N1 carrier on radio and coaxial cable

A practical illustration of the versatility obtainable in applying modern types of carrier telephone systems to radio facilities is given in an application of 48 channels of the Western Electric Company type-N1 carrier to a 2-section radio system in an area served by The Pacific Telephone and Telegraph Company. The radio system, with the unusual feature of combining two types of radio equipments, has a Western Electric Company type-TD-2 terminal at Los Angeles and type-TE-1 terminal near Ventura, with one intermediate TD-2 repeater at Oat Mountain, near Chatsworth, California.
