Abstract

530,443. Automatic exchange systems ; metering systems. POLLAK, J. E. (Associated Telephone & Telegraph Co.). May 11, 1939, No. 14132. [Class 40 (iv)] A register translator, in addition to transmitting the routing digits corresponding to a received name code, transmits the name code' untranslated if the call is to be ticketed, the routing digits being sent as digital impulses over one leg and the name code as code impulses over the other. General description. If a call set up by a subscriber T1, Fig. 1, with the aid of a register translator RT is to be recorded the charge rate and the exchange code as determined by the position of the BC switch are transmitted to the trunk line control circuit TLCC seized by the first code selector over one leg while the numerical digits are being sent over the other. At the tandem exchange 51 the numerical digits are corrected by a mechanical impulse repeater MIR in the outgoing junction. With the help of a converter C the exchange code and rate are stored in TLCC as well as the numerical digits and the calling number as determined by identifying apparatus D1. Apparatus C, D1 are then restored to common use. When the called party replies, timing equipment in TLCC comes into action and at the end of the call TLCC is associated by CF with a printer controller to which the whole of the stored information is then transferred. The ticket then prepared bears in addition to this information the date and time and the calculated value of the call. Specifications 516,348 and 516,409 are referred to. Selection of 1st code selector, Figs. 3 and 4, and operation of A-digit switch Fig. 9. The line switch, Fig. 2, operates in known manner and when cut-off relay 210 switches through, line relay 370 pulls up in the first code selector followed by 410, 350, 450, 330, 340, 420, 360. Switch ADF then hunts under control of 430 for an A-digit switch. Operation of 430 energizes 400 which changes the circuits of 340 and 410 and energizes impulse relay 960 in the A-digit switch. Dialling relay 980 and relay 970 follow and dialling tone is sent back. Digits dialled are repeated by 370 over wiper 913 and the A-digit switch is stepped vertically in the usual way and hunts by self interruption under control of 950 for a register translator. Operation of 950 is followed by that of 940 and by the relapse of 960, 970. Register-translator, Figs. 5 to 8. Relays 560, 550, 530 pull up initially. Dialled digits are repeated by 560 to the magnets 715, 716 of the BC switch and the magnets 721, 801, 811, 821 of the numerical registers, the units register acting as digit distributer with the help of series relay 880 and energizing 540 in the case of calls which are to be recorded when the exchange name has been received to mark the wanted name code and the charge rate in a series of W, X, Y, Z groups in the bank T2 of switch T. At the same time a circuit is made for a relay 620 which initiates the transmission in known manner of the route code, the impulses being sent over the loop in the case of local calls but over the negative wire only in the case of recorded calls. This is followed at once in local calls by the numerical code. In the case of calls to be recorded, however, wiper CN3 of the sender control switch when the route code has been sent makes a circuit for 520 which disconnects 620 to suspend the sending operation and connects 510 (upper) to the positive wire 602. When the toll line control circuit has been associated with a converter, battery is fed back over this wire and 510 disconnects itself from wire 601, locks and releases 520 to connect up 620 again, whereupon the numerical digits are sent. In this case, however, 510, also makes a self-interrupting circuit for 500 which sends impulses to stepping magnet 731 of the switch T. Each operation of 500 also connects ground over resistance 558 to the positive wire, this resistance being short-circuited in certain positions of the switch depending on the position of the BC switch and the jumpering at 714. Consequently for each of the four digits of the name code and charge rate four impulses are sent, those corresponding to unmarked terminals being highresistance earth impulses and those corresponding to marked terminals full earth impulses. When all the numerical digits have been sent relay 610 is operated over CN3, the A-digit switch and register-translator are released and the switch ADF associated with the first code selector is restored. Double-wiper first code selector. The first digit is repeated by 340 through 360 (upper) to vertical magnet 392. At the first step relays 460, 470 are operated over their middle windings. At the end of the digit the rotary magnet operates in a self-interrupting circuit and the switch hunts under control of relays 460, 470 which are held energized by busy grounds over their lower and upper windings respectively when their middle windings are disconnected by the interrupter springs. When an idle line is found one of these relays falls making a holding circuit for the other, stopping the switch and energizing 440 and the selector is thus switched through to the trunk line control circuit, Figs. 13 and 14. Trunk line control circuit and converter, Figs. 13..15. Relay 1505, energized over the negative wire when the first code selector switches through, is followed by 1500, 1640, 1520. A self-interrupting circuit is made for magnet 1691 of CF which hunts in the part of its bank giving access to converters under control of 1620 which operates in due course over 1693, stops the switch and energizes 1720, 1660 whereupon 1670 pulls up to complete the switch-through to the converter. Relays 1765, 1760 are now connected in series to the negative wire 428 to operate 510 in the translator. In this circuit 1760 operates (but not 1765) and energizes magnet 1791 of switch R. When 510 immediately disconnects itself 1760 falls and R moves its wipers. The numerical digits are repeated by 1505 over the junction and over series relay 1755 to magnet 1777 of a translating switch N in the converter. Relay 1755 energizes 1750 which energizes magnet 1681 of distributer switch 2S in the control circuit. At the end of each digit a temporary circuit is made in the interval between the relapse of 1755, 1750 over wipers of the translating switch N and of the distributer 1S in its normal position for setting W, X, Y, Z registers I.. IV, Fig. 14 in accordance with the numerical digits of the wanted number, the switch 2S being allowed to step on and the translating switch being sent to its next starting position by each relapse of 1750. During the registration of the fourth digit, wiper 1775 of the translator switch energizes magnet 1781 of the distributer 1S and after the transfer the switch steps. The coded impulses transmitted over the positive wire are received by the relays 1760, 1765 of which both are energized by the strong impulses and only 1760 by the weak ones. All impulses thus step round switch R and the strong impulses are recorded on the appropriate relays W, X, Y, Z groups connected up over its wiper 1793. After all four digits have been received the switch automatically returns home. When all the digits from the register translator have been received a selfinterrupting circuit is made over wipers 1794 of R and 1787 of is for 1745 which then sends impulses to magnet 1681 of switch 2S and to magnet 1781 of switch 1S. In successive positions of these switches the setting of the converter registers I .. IV at the left of Fig. 15 are transferred to the control circuit registers V .. VIII (not shown in detail) at the right of Fig. 14 after which 1745 is disconnected. Meanwhile apparatus forming the subject-matter of Specification 530,614 has been identifying the calling line, and when this operation is completed 1730 re-starts 1745 and switches 1S, 2S are stepped together again to transfer the calling number from registers V ... VIII in the converter to registers IX ... XII in the control circuit. After this switch 2S in position 13 energizes 1650 which sends 2S home and releases 1670, 1620, 1660 to release the converter Toll line control circuit timing apparatus. Selection of printer controller. When the called party replies 1540 responds to the usual current reversal and connects an impulse wire to 1545 which then delivers twelve impulses a minute to 2T. After a fifteen seconds grace period an impulse is given over wiper 1564 to magnet 1571 of units timing switch 3T. At the end of the first minute wiper 1564 partially energizes 1530 which pulls up completely when 2T moves on. At the end of the third minute a circuit is made over 1564 to step 3T on a step and thereafter 3T is stepped on each minute. After nine minutes a circuit is made for the magnet 1591 which steps on tens timing switch 4T. If the connection is held for ninety-nine minutes, 1525 is operated and gives an alarm. When the call is cleared 1500 falls and energizes 1630 which guards the toll line, initiates the operation of a delayed alarm, drives CF to position 13 from which it starts hunting for a printer controller, Figs. 16 ... 19, under control of 1620 which in due course pulls up in series with 1810 in the printer-controller, locks itself and energizes 1660. Since the circuit of 1630 involves offnormal springs of 3T, no recording takes place of ineffective calls cleared within the 15 seconds period. Printer-controller Figs. 16 ... 18. Relay 1810 energizes 2025 to cause the date and time to be signalled from DTO to the registers XV to XXII as described in Specification 516,409. 2025 also energizes 2050 which cuts off 2025 but holds itself and energizes 2120. With 1660, 1630 operated 1625 generates impulses again and delivers them to relay 1670, magnet 1681 of the distributer switch 2S and magnet 1836 of distributer switch 1P in the printer-controller. By this means the records of the registers I to XII in Fig. 14 are transferred in tu
