Abstract
1525079 Substation apparatus STOPPANI S A ETABS POUR LA MECANIQUE DE PRECISION ET L’ELECTRO-MECANIQUE and OLIVER TECHNIK AG 23 July 1976 [31 July 1975] 30857/76 Heading H4K An apparatus, for connecting a telephone line to a calculator having a printer and a display, comprises means for separately detecting dial and charge pulses, processing means for recognizing dialled digits and counting charge pulses and control means for issuing instructions to the calculator for printing each dialled digit, displaying the current charge of a call and upon termination of the call for printing the total charge. In the embodiment a unit 401 receives data from the line and detects separately the digit pulses of a dialled number and the charge pulses. The digit pulses are supplied to a processing unit 301 which has delay circuits for distinguishing true dialling pulses from momemtary interference pulses. Unit 301 detects the end of each pulse train forming a digit and also the end of a call. The charge pulses are supplied to a unit 402 which generates the charge-calculation and charge-printing-order sequences. It also receives two signals from unit 301; DCR (end of call) and FUH (inter digit pause). On reception of a charge pulse unit 402 generates instructions for the charge unit to be added to the charge indicated by the calculator. These instructions are supplied to a unit 302 which also receives the dialling data from unit 301 and through an interface 303 instructs the calculator. During dialling unit 302 counts the pulses in each digit and transmits the numerical value of the digit and the instruction to “PRINT” to the calculator. At the end of this printing sequence unit 302 transmits the orders generated by unit 402 for the display and printing of the charge. Unit 302 also includes an oscillator which can operate in two frequencies, a low and a high frequency, for timing the orders sent to the calculator; the high frequency is used when the charge pulses are to be added and displayed and the low frequency when the dialled number and the total charge are to be printed. Unit 303 comprises gates which are connected across the key contacts of the calculator, through a multiple plug (5, Fig. 1, not shown), and they simulate pressing of the keys by shorting the respective contact of each key when ordered by unit 302. A plug (4, Fig. 1) connects the apparatus to the telephone line, another plug (3, Fig. 1) connects it to a power supply and a lamp (305, Fig. 1) indicates when the apparatus is in use, so that the calculator may not be used in its normal operating mode, i.e. calculating.
