CARDS FOR CONVERSATION<\/strong><\/p>\n

To find out how to route Long Distance calls a dial system needs lots of information\u2014fast. To provide it Bell Laboratories engineers developed a new kind of card file\u2014one that dial systems can read.
\n<\/span>
\nPunched holes on metal cards tell how calls should be handled. When a call arrives the dial system “asks” the “card file” how to proceed to a particular area. Instantly the appropriate instruction card is displaced so that its pattern of holes is projected by light beams on a bank of Phototransistors. In a flash the Phototransistors signal switches to set up the best connection. Cards are quickly changed when new instructions are needed.<\/p>\n

The “card file” will have its widest use in speeding Long Distance calls that are now dialed by a telephone operator and may one day be dialed by you personally. It is another example of how Bell Telephone Laboratories helps telephony to grow, as costs are kept down.<\/p>\n
