Abstract :
Completion of the longest telephone toll cable west of the Mississippi gives San Francisco and Los Angeles a 275-circuit all-cable communication channel, the equivalent of three of the latest-type 60-wire open leads completely equipped with carrier systems. The project cost ten million dollars, involved some heavy construction problems, and provided an important step toward an ultimate all-cable transcontinental system.
