CARD TRANSLATOR FOR NATIONWIDE DIALING 1045 



CSP. Considering these factors, it was found desirable to design the 

 card translator to accommodate over a thousand cards. 



TRANSLATORS 



Since several translators are needed in a CSP, for further economy 

 and consistent with service hazards, the translators are segregated ac- 

 cording to the groups or kinds of cards they contain. These are as 

 follows : 



Decoder Translators 



These translators contain the local three-digit office code, the three- 

 digit area code, the alternate route code and, where space permits, some 

 of the high usage six-digit foreign area code cards. Several of these 

 translators are furnished, one for each decoder, depending upon the 

 volume of traffic handled by the particular CSP. 



Foreign Area Translators 



These are furnished, one or two per office (maximum 19), for each 1000 

 or so foreign area code cards. These translators are in a common pool 

 and the particular one is selected when needed for the six-digit code to 

 be translated. 



Decoder Foreign Translators 



If there are sufficient high calling rate, six-digit, foreign area cards, to 

 justify it, these translators may be provided, one per decoder. 



Emergency Translator 



Provisions are made so that the emergency translator can be sub- 

 stituted for any other translator by changing the cards of the trans- 

 lator in trouble to the emergency translator. 



TRANSLATOR OUTPUT 



The translator output information required for a CSP office for na- 

 tionwide dialing must be very extensive to accommodate the many 

 varieties of routes over which calls must be completed. The need for 

 automatic alternate routing, code conversion and the storing and sending 

 forward of digits also affects the need for increased translation output. 

 The output is provided by means of the 1 18 holes in the face of each card.
