JPS603255B2 - Frequency registration method for public lines that use large amounts of money - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a frequency registration method when a public telephone can be used to make multiple calls using high-value coins, that is, one coin.

Conventional public telephones that use large amounts of money are Boxloo yen public (
Commonly known as yellow 10 biq public), in this case, even if you finish the call in the middle of 100 yen, there is no need to register the remaining amount after that, so you can register it and it is gone.

However, if this remaining power is not registered, the amount registered at the station and the amount stored in the pay box of the public telephone will not match, and for example, in the public telephone installed by commission, the amount equivalent to the remaining power is large. A discrepancy occurs where the items are stored.

The present invention has been developed in view of this point, and the number of points that can be used for money calls is registered in bulk after the end of a high-value currency call, and if there is a call for appetizers during the bulk registration, the bulk registration is temporarily suspended. death,
The system is characterized in that the batch registration is restarted after the termination of the incoming call, and its purpose is to eliminate the above-mentioned discrepancy, as well as to omit the required circuit for regulating incoming calls during the batch registration, and to pass the call.

FIG. 1 shows an embodiment of the present invention, and in its configuration, C is the C line of a line link frame/LLF that accommodates subscribers of a known telephone exchange, that is, public telephones.

-S is a relay that detects the earth condition of the C line, and operates during a call when a call is made and an incoming call is connected. The winding circuit of the rva3 contact is not shown in this diagram, but when connected to the
This is the contact point of the RVA relay that operates when the polarity of the outgoing trunk/OGT, internal trunk/OT, talk trunk/TKT telephone line to the public telephone is reversed, and the berth is detected (not shown). Although the winding circuit of the hco installation point is not shown in this diagram, it is the contact point of the closing relay HC that is operating as a result of identifying that the public telephone has stored high-value currency, and the registration of the number of calls possible is completed. It is working until now. The HCI is a relay that operates when a call is made using a large amount of money, that is, when the hco contact is closed, and the aforementioned trunk lever, that is, the rva3 saddle point is closed, and when the S relay is restored, that is, when the call ends, the relay is activated via the s3 contact. The operation continues until the above-mentioned hco contact point is opened, that is, the registration of the number of possible calls using high-value currency is completed. Although the winding circuit of the int contact is not shown in this figure, after the CI relay operates, the int contact repeats the operation recovery (intermittent operation) at a constant cycle, and stops when the HCI relay recovers. The T relay is a frequency registration relay operated by the hc12 contact of the above-mentioned CI relay and the above-mentioned int contact. M○, M1, M2 relays are the contact point t of the T general appliance mentioned above.
This is a counting circuit controlled by LO, and the conditions for starting the counting operation are the above-mentioned case of the rva4 contact being closed by the trunk opening, and the case of the above-mentioned S relay contacts s9 and H.
This may be due to the contact hcl' of the CI relay. SO~
The S4 relay is a counting circuit controlled by the contact voltage of the T relay described above, and its starting condition is the hco contact described above. The RL relay is a relay (a circuit for detecting the completion of callable number registration) that operates when the counting circuit relays of SO to S4 mentioned above count 10 times. The HC relay on the line will be restored. That is, FIG. 1 shows a case where the number of possible calls for large amounts of money is 10. M old T is a known frequency meter. FIG. 2 is an operational diagram of frequency registration during an outgoing call using the circuit example shown in FIG. 1, and FIG. FIG. 3 is an operation diagram of frequency registration when

The embodiment of the invention shown in FIG. 1 will be described below with reference to the operational diagrams shown in FIGS. 2 and 3.

First, frequency registration during an outgoing call will be explained.

During an outgoing call, the RVA controller (not shown) operates due to the above-mentioned trunk berth, and the HCI
The total crab operates, and the T relay connects the above-mentioned int contact and hc
Operates with 12 contacts. When this T relay operates, M
The 0 and MI counting circuits perform a known counting operation through the tlo contacts. In the old T frequency meter M, this T relay works, H
When the CI relay is operating, that is, 1 registration is performed during a call using the tll contact and the hc13 contact. Next, when the T relay is restored, both the M0 and MI counting circuits operate, and m
03, HCI relay is restored by mill contact. H
When the CI relay is restored, the 1-registration operation during the call ends. The SO-S4 counting circuit relay identifies how many high-value currency call enabled frequencies have been registered during the outgoing connection using the t8 contact. Next, a description will be given of how to collectively register the remaining number of callable points when a call is terminated in the middle of the number of available callable points for large amounts of money.

As is well known, when the call ends, the C line of the line link frame mountain F is opened, the S relay is restored, and the s3 contact returns to its normal state, thereby activating the HCI relay.
When the HCI relay operates, the T relay becomes int as described above.
Continuous and intermittent due to the intermittent operation of the contacts. When the T relay performs intermittent operation, the frequency meter MET performs bulk registration and the S
The O~S4 counting relay performs a counting operation, and when the number of 1 width exceeds 10, the R relay operates, and as mentioned above, the hc (not shown) is activated.
Restore the HC relay, which is a 4-contact winding circuit. hc
When the O contact returns to its normal state, the HCI relay is restored and the alternating operation of the T relay is stopped. Next, the operation when there is an incoming call during the batch registration performed as described above will be explained with reference to FIG.

FIG. 3 shows a case where there is a spring call after the 8th registration of the registration during the call and the above-mentioned batch registration after the end of the call, that is, the S relay is activated. When activated by an incoming call, the S relay uses a circuit not shown in FIG. 1 to control the known communication lines A and B to be connected directly to the line link frame LLF and a public telephone (not shown) regardless of the call control circuit, and The operating circuit of the HCI relay is disconnected at the point after s3. However, the HCI relay will continue to be held by hclo. Also, by closing the s9 contact, M0, MI
The relay performs a one-time count of the tlo contacts as described above.
As a result, the HCI class electric appliance is restored by the same operation as the frequency registration explained during the outgoing call. In this way, when the HCI main appliance is restored during an incoming call, the S relay is operating during the incoming call, and the above-mentioned RVA relay does not operate as is known, so it is impossible to create a circuit to operate the HCI main appliance again. Therefore, the T-relay does not operate, the batch registration stops, and the counting circuit maintains its state, and when the S-relay is restored after the incoming call ends, the batch registration operation is performed again. Here, as explained above, if there is an incoming call during the batch registration of remaining degrees, the reason why the incoming call is given priority and the batch registration is temporarily suspended is that the incoming call goes through the expensive exchange ladder. This is because it cannot be disabled.

The purpose of registering the remaining power in the case of an incoming call all at once after the end of the incoming call is to clarify the logic by separating the outgoing and incoming calls. Also, as above, there may be a case where a re-call is made during the batch registration of remaining powers, but in this case, unlike in the case of the incoming call, the expensive exchange ladder is not passed, and the remaining powers are not registered. Re-registration and re-calling will be regulated for reasons such as the complexity of managing the registration of new degrees.

Specifically, it is conceivable to continue registration with silence or busy tone BT status in response to a re-call. As explained above, in the embodiment shown in FIG. 1, by keeping the counting circuit relays SO to S4 operating during an incoming call during batch registration, batch registration is performed using the counting circuit operation during an outgoing call. It is possible to stop the service, and after the incoming call ends, it is possible to restart the batch registration again.

As detailed above, according to the present invention, even if there is an incoming call during bulk registration after the end of a high-value currency call, there is no special storage circuit or incoming call restriction circuit provided during bulk registration, and incoming call restriction is implemented. It is possible to register the frequency of public lines that use large amounts of money economically without having to do anything.
