Definitions

  • any telephone anywhere in the world could be used even without computerised facilities to contact a specific person. Such person moreover would become aware of the callers identity before the telephone had to be answered.
  • Figure 1 shows a system block diagram of the unit
  • Figure 2 is a schematic diagram of the ring detector and remote on-hook detector
  • Figure 3 is a schematic diagram of the dial- pulse counter.
  • Figure 4 is a schematic diagram of the acoustic signal generator (block 1) ,
  • Figure 5 is a schematic diagram of the acoustic signal generator (block 2) .
  • the ring signal is rectified by diode Dl.
  • the opto-coupler PH01 causes the input of the AND gate IC6 to go low.
  • the output of the IC6 also goes low since opto-coupler PH02, part of the remote off-hook detection unit is unenergised due to the open circuit at relay 3.
  • the low/high transition at the input to the counter IC4 that occurs when a ring pulse ceases causes the count to increment.
  • the output Q7 will go high, energising relay 1 and causing the incoming telephone line to be switched to relay 3.
  • the signal RE which turns on the relay also resets the pulse counter so that it is ready to count the dialled pulses .
  • the received pulses are rectified by diode D2 and low pass filtered by R5 and C3 tnen amplified and finally are counted by IC2:A. Because there is one more pulse produced by the circuit than dialled due to the energy in the "end of dialling" spike a count of two pulses is made to signify "1" has been dialled by activating the acoustical signal for "1".
  • the binary representation of the count at the output of IC2:A is used to drive a multiplexer, IC3 switching high one of the output Cl to CIO. These outputs form the input to the acoustical signal generator 6.
  • relay 3 When relay 3 is energised the acoustical signal is unaffected.
  • the opto-coupler PH02 is connected across the line. Because the called party has not yet lifted the hand- set the line is terminated by a 10K resistor in series with the phot ⁇ diode. The dc voltage from the exchange turns on the output transistor of the opto-coupler, causing a low transition at the input to the counter. If the calling party abandons the call the opto-coupler output will go high causing a low-high transition at the counter input and the output at Q7 will go low, causing relay 1 to be de-energised and restoring the telephone line to the ring detect unit 2 ready for the next call. At the same time the pulse detector is reset to a count of zero inhibiting the acoustical signal.
  • It may also be capable of distinguishing external and internal calls by sound.
  • a mechanism may also be included in the system to provide sound differentiation for each extension phone if used.
  • the recipent can choose not to answer unwanted calls .
  • the system can be used to prevent crank calls.

Abstract

Dans le circuit de téléphone ou d'interphone décrit, l'introduction d'un premier numéro de ligne par le demandeur localise le terminal récepteur désiré et, après le début du signal de sonnerie d'appel, l'introduction ultérieure d'un second numéro de code par le demandeur produit une tonalité présélectionnée distincte au niveau du terminal récepteur, laquelle permet d'identifier le destinataire désiré de l'appel ou de déterminer l'identité du demandeur en fonction du second numéro de code. Ledit circuit peut comprendre un système de trois relais (1, 3 et 7) et cinq sous-systèmes électroniques, à savoir un circuit détecteur de sonnerie d'appel (2), un compteur d'impulsion (4), un détecteur à distance de combinés raccrochés (5), un générateur de signaux acoustiques (6) et un détecteur local de combiné décroché (8).
