Pay phone for local and personal dialing

The invention relates to a payphone for choice of location and person.

The invention is based on the object known To simplify coin operated telephones of this type and without the help of a Verraittlungspereon on a particularly simple one Way to enable direct choice of location and

In the system according to the invention, a coin inserted by the user is picked up by reversing the polarity of the current flowing in the conversation platform during the conversation. Local calls can be carried out in the same way as wle ^{: 1 with} the known systems. If a long-distance call is made, in the system according to the invention the inserted and stored coins are received one after the other by MÜnssannelslgnale which, during the call, come from the office but the transmission line to the payphone concerned. If the polarity reversal of the transmission current is used as a short-cut signal, a

If this participant does not insert another coin, the conversation will be terminated when the polarity of the next reverse current pulse changes by interrupting the transmission current completed. Since no additional coins have to be inserted with a local call, a tone signal ("pay tone") to indicate that no external information is stored, not required. Therefore, if the called party answers, signals are sent out by the control center that differentiate between local calls and long-distance dialing calls in the coin-operated telephone will.

manufactured. If the called subscriber answers, it changes the polarity of the transmission streams and reverses back to the original polarity aurüok, as in Fig.5a illustrates let (this signal is given when answering of a local call called the ttünseammelslgnal).

Through this polarity reversal, the relay N ₍ which monitors the response, is operated via the following circuit:

L2 (+ VrI-CHI-P-KSl-Di-CCLl-K-De-HSl-Ll (-)

When the polarity of the transmission current changes, it reverses the current direction of the relay F, which is used to distinguish between local calls and long-distance calls; so that this relay begins to drop out. However, since the relay F has a slow drop-out characteristic, the relay H _c, which monitors the response, is actuated before the relay F has dropped out (see Figure 5a). If the relay M is actuated, "before the relay F has dropped out," an (as shown in Fig. *) Can distinguish the call as a local call. The mechanically held relay F attached its operating conditions; the connections a and b of the tone generator TQ are closed, so that an operation of this ** tone generator is prevented. The mechanical actuation processes of the relays F and M will be explained in more detail later.

The contact ii2 eliminates the hook-and-loop holder contact BSI and the dialing impulse agreement Oi course and opens the sound of the course-closed microphone T to establish a non-regular connection Prevent the use of the rotary dial and the hook switch and an irregular long-distance call. By actuating the relay K, the following circuit is formed, the coin collecting relay F is actuated and the previously inserted coin is placed in a coin container:

ANKOHMBKDBR KOt:

The Wacker We rings with a ringing signal. the Hook holder contacts HS1 to HSJ are activated when you lift off of the handset. The call signal then flleit Above the following circuit, the xieebanleoh interlocking Relay R is activated:

Li-C3-HS2-R8-R- «2-KSi-P-CHl-ri-L2

By actuating the relay R, the following direct current circuit is formed, which starts a conversation:

The relay R stops as well as the relay M after it has been actuated. The hook switch and the relay R will be canceled after the call has ended by hanging up the handset.

The pointer inside is therefore limited to the fact that the end of a plate 10 is indicated. the part B of the control disk applies in the non-actuated state. If the relay P is actuated, the end of the lever 6 of the armature of this relay moves to the right and actuates the relay contact. At the same time, a rotary movement of the control disk 4 Is Uhreeigerslnn is not interrupted. In this state the control disk k is of course not rotated, since its plate 10 rests against part E of the control disk 3 in the non-actuated state Relay W to the left and actuates the contact »At the same time, the control disk 3 rotates around the axis 3 in the counterclockwise direction. The part B of the control disk 3 is brought to a standstill by the end of the lever 5. The relay M is therefore held mechanically in the actuated state. Simultaneously with the rotary movement of the control disk 3, the control disk H rotates about the axis 2 in the clockwise β inn. The part D of this control disk H hits the end of the lever 6 which has been moved to the left. As a result, the relay P is also mechanically held in the actuated state. This state is shown in Fig. * A. The state shown is maintained until the current is interrupted by hanging up the handset, with the control disks 3 and 4 returning to their starting position at the same time *

If an Uhterbreefring-ltaeklapiils is issued as in Fig. 3, then the relay F drops out during the current interruption afterwards. The relay M is titled by the return pulse. The lever S and the control handle 3 move and the above-mentioned state is maintained. The part B of the control disk 3 is removed from the plate 10, however, since the relay * F has already dropped out. The control lever H therefore tries to turn clockwise su. The relay P remains in the non-actuated state, since part C of the control disk 4 strikes the end of the lever 6 and comes to a standstill. This state is illustrated in Fig. Hh. The control disk 3 is surflekcendet in the actuated state by hanging the handset as explained above. ·

As explained above, the energy of the periodic signal on the calling side is greater in the coin-operated telephone for long distance dialing than in a periodic call system with a normal periodic alternating current signal, since a radio pulse is the periodic signal of the f _% . MUn * recording is used (as shown in Fig. 1). At the polarity quarrel. of the transmission current, the gradual decrease and the gradual increase in the Aat takes place, the transmission current being sent to the transmission line via the low-pass filter with a lower limit frequency than corresponds to the speech frequency range.Parallel to the circuit in which disturbances caused by the reception relay and the coin contact can be connected, a capacitor C6 is connected, in series with a choke

rinsing CHI ancsordnat is. The elements are located between the transmission line, which prevents the transmission of interference onto the line. To prevent tu, daft when Polaritätswechael übertragungastromes of the microphone T current is supplied to the * Qbartragungastron is rectified (see FIG. 5 shows), so-daft the Stromriehtung is fixed. A capacitor with a large capacity is charged by the current l at the same time the current is fed to the microphone T * via the choke coil CHS. If, therefore, no current is present when the transmission atom changes polarity, the capacitor Ck supplies a discharge current to the microphone Ί and prevents the transmission from being interrupted. Furthermore, local calls and long-distance calls are provided with three MCtataufnahae signal systems. the number tone generator TO is controlled so that it distinguishes between xwisohen location calls and pern calls; herefCU * is the combination of the * primary division of location "and.Relay T, which is used for remote calls, and the relay M, which is used to monitor the response.
