Dur ing this operation, the armof the zone marking 'deviceZm will be set on its contact 9 and remains there during the whole call. Thus,.the positive potential of Zm is transmitted to the second arm Za. of the zone marking device. When the second characteristic numeral 2 is selected, both arms ofselector Zm are brought 'on. their second contact.
  • the second arm Za of Zm is connected withthe second arm Zot of the marking device Zm and according to the .third numeral bringing the latter arm on I, 3 or 14 to 9 the positive potential is transmitted to the contact 30 of the coin counting device Me or to its'oontact 50. After inserting of the. correct amount of money the arm Mza of the counting device is brought on the corresponding contact and the communication will be established as stated above.

  • the arm ZA of selector 2M is connected with the positive pole of the battery. Its contact row is, the contacts LB and 0 excepted, connected with the lamp for twenty cents. The result is that when, for instance, the calling subscriber wants to have a communication with asubscriber which is directly connected with the main office the lamp for twenty cents'will flash up already after the selection of the first numeral. The adjusting of the arms ZA and ZA remains without further influence.

At the end of the second series of impulses the calling subscriber already knew about the'tax to be paid.
  • the third series of impulses has caused also the adjustment of arm 'ZA but without any lamp being influenced because the second arm 2A of selector ZM is connected with contact 9 of selector 2M If the calling subscriber Wanted a communication with a subscriber or the outer network he By this selection the second arm ZA of selector ZM has been connected with the positive pole of the battery. According to the second numeral this potential has been transmitted to the one or the other of. the arms of the selector 2M which causes the flashingup of the lamps for 50 or 30 cents respectively in accordance with the series of impulses emitted.
