Supplementary Cabinet forHandling Long Distance Calls War increased phenomenally thenumber of long distance conversa-tions in 1942, To handle this greatincrease in calls, much larger quanti- the number of operators that must beused for this work. A good illustration is the smalltable-mounted cabinet used to aug-ment switchboards handling outgoinglong distance calls, the use of whichavoids installation of additionalswitchboard positions. Each cabinetserves two operators, and these op-erators, with limited assistance fromoperators working at the regular I. These supplementary cabinets used for handling long distance calls conram less than one-sixth of the inetal in regular switchboard positions—although requiring twice as many operators to handle the same volume of traffic ties of critical materials would havebeen required for additional switch-ing equipment, wires, and cables thanwere actually used, had not variousexpedients been adopted. Amongthese expedients are changes in themethods of handling long distancecalls in order to avoid using addi-tional materials. Generally, thesechanges increase somewhat the timerequired to complete calls and add to switchboard positions, can generallydo all work connected with handlingoutgoing long distance calls. Because of certain limitations, theoperation of the cabinets requiresdouble the number of operators thatwould be required to handle the samenumber of toll calls on regular switch-board positions. In these times, thedisadvantage of using twice as manyoperators is
