Description

Circuit arrangement for counting. The invention is a Circuit arrangement in which the subscriber line has two counting devices are assigned to the billing of connections of different values.

Such arrangements are provided for those participants who a separate registration of the unpredictable conversations they have had (Local and long distance calls). With a @ known electrical or mechanical Double counter can only count separately take place. Counting pulses that are sent to the double counter during an active connection given, lead to a wrong result.

Another known circuit arrangement allows payment or Billing both during and after the call. this will This makes it possible for a long-distance connection to switch electricity pulses to one to the. Speech wires lying relay are given that the switching of the in the Test wire makes lying counter: With this arrangement, an additional one occurs Attenuation in the speech circuits.

The invention is also concerned with the separate counting or counting. Logging of different-valued connections both during an existing connection Connection 'as well as at the end of the same. It avoids a special power source for counting and attenuating the speech circuits. According to the invention; this achieved by the fact that the participant approach orderly Switching means by one when establishing any countable connection, z. B. Reporting the called party, coming into effect, registering the total number of calls Counter affecting count the other, the charges for high quality Switch on the connection-recording 'counting device' in preparation. Such Arrangement does not require any drastic changes;! - in selection.

Using the in A: bb. The invention is explained in more detail in the circuit examples shown around 2. Fig. I shows the necessary change B in the preselection organ for double counting. It is assumed that the subscriber had established a connection. The preselector has found a free subsequent connection device in a known manner, switched the subscriber through and blocked incoming calls. The subscriber has made the connection. Relay A takes the place of the usual counter in the preselector. It records the counting pulses received during or after the call. By means of the contact a, these are transferred to the counters located in a special circuit. Contact a closes the circuit for the counter Z i and <read relay B: +, a, b I, Z i, B (i-2), - when the first counting surge arrives.

Contact b I, designed as a drag contact, prepares the switchover to counter Z 2: +, a, b I, zä 1 I, Z 1, B (1-2), -.

fitber contact b 1I. and the switching arm d in the preselector, binds Relay B Via a second winding for the duration of the connection: 'r, B (3-4), switching arm d, -.

After the end of the counting pulse, relay A drops out again. By opening the contact a in the Zähderschaltung the circuit for the counter z i is interrupted, which is connected to the contact zä i. the counter z 2 finally prepared for the inclusion of further incoming counting pulses. Now take more pulses to the relay A, then these are transmitted by means of the contact a to the counter Zä. 2

+, abl, zäiI, z2, wii, -.

When the connection is released, relay B is made to drop out, as the switching arm d of the preselector interrupts the circuit. In the counter circuit is again switched to counter Zä unige- i, which can accommodate the first in a new connection via contact a of the transferred count.

While the counter z i counts the number of calls made by the subscriber, the counter z 2 detects the charges that: arise for a long-distance connection. In Fig. 2 the counters are switched in another way. If the first counting pulse is transmitted via contact a; so the counter Z i and relay B (1-2) responds, which, as already mentioned, remains in the preselector over a second winding. The counter Z i responds before the delayed relay B: +, a, b III, Z i, B (1-2), -. Contact b III switches to counter zä 2 , which, however, since relay A has still responded, is short-circuited by counter contact zä i II. The counter Z i receives - via the resistor Wi 2 holding current: If the circuit is interrupted by contact a, then the counter Z i drops and can no longer respond via the resistor Wi 2 when a second counting pulse is transmitted through the contact a to the counter device. Rather, this arrives at the counter zä 2, @ because the counter contact zä i II has released it: +, a, b III, z 2, Wi 3, -. All further counting pulses are now, as relay B, as already mentioned, remains in a circuit of the preselector, transferred to the counter Z2.

Claims (3)

PATENT CLAIMS: i. Circuit arrangement for counting, in which the subscriber connection line is assigned two counting devices for recording charges for calls of different values, characterized in that switching means (A, B) assigned to the subscriber connection line are replaced by a connection that is subject to counting when any connection is established, e.g. B. Reporting of the called party, coming into effect, the counting device registering the total number of conversations (Z i), which influences the other counting device that prepares the charges for high-quality connections. 2. Circuit arrangement according to claim i; through this characterized that Idas switching means (B), in the circuit of the d = ie total number of calls registering counter responds. and in a via a switching arm (d) four pre-selection device (VW) running circuit binds. 3. Circuit arrangement according to claim i, characterized in that the counting pulses respond to the charges Counting devices that record different conversations by one in the test circuit the preselection device arranged switching means (A) are transmitted.
