Title: Date translator and recording system
IPC: H04L13/16
Filed: 1972-08-24
Abstract: 1370553 Data recording system GENERAL COMPUTER SERVICE Inc 24 Aug 1972 [26 Aug 1971] 39442/72 Heading G4H A data recording system comprises a pushbutton telephone handset 102, Fig. 1 (not shown) connected via a telephone network (110) to a data set (114) which translates input signals, of different frequencies into different pairs of signals 3<SP>1</SP>-11<SP>1</SP>, Fig. 2, which it feeds to a translator, Fig. 2, comprising logic devices 51-59, 61 responsive to different signal pairs to deliver a D.C. pulse of fixed duration to a key tape unit (122). With the exception of the translator, the above-mentioned system components are standard pieces of equipment; handset (102) has ten buttons for digits 0-9 together with "erase" (error home) and "skip" buttons (with corresponding devices 60, 62), depressing one of which generates a corresponding tone. A handset is connected to the system by "dialling" the data set telephone number, and then the data to be recorded. Data set (114) changes a received digit tone into a signal on one of leads 3<SP>1</SP>-6<SP>1</SP> and on one of leads 9<SP>1</SP>-11<SP>1</SP>, e.g. digit 1 tone on leads 3<SP>1</SP>, 9<SP>1</SP> so as to enable NAND gate 71 in logic device 51. The NAND gate output changes from 0 to -5V, this being differentiated by a capacitor Cl to give a negative pulse which turns on a transsistor 73: the transistor stays on for the duration of the negative pulse thus producing a pulse at output terminal 1 whose duration is independent of the duration of the signals 3<SP>1</SP>, 9<SP>1</SP>. The capacitor C1 is omitted from 60 and 62, giving rise to erase and skip signals of duration depending on the input signals. When a complete record has been received by the key tape unit (122) a signal therefrom operates a relay R2 which interconnects terminals 20<SP>1</SP>, 24<SP>1</SP> connected to the data set which is thereby caused to transmit an audible signal to the user at the telephone set.
