OFFICE CALL SYSTEM USES MORSE CODE (Nov, 1934)

OFFICE CALL SYSTEM USES MORSE CODE

An office call system employed by officials in the traffic department of the Western Union Telegraph Company in New York uses telegraph code. Sub-ordinates are summoned by an official merely by tapping out the initials or call letters of employees on a key conveniently placed on his desk. Buzzers located on various columns carry the dot and dash message to all parts of the department. Since most of the employees are familiar with the telegraph code, none has any trouble deciphering the buzzing that to the average person would be wholly unintelligible. On occasion, the private telegraph system is used by officials to hold short conversations over distances up to 100 yards.
