[Problems to be solved by the invention]
SUMMARY OF THE INVENTION The present invention is a new premises equipment that enables use of premises equipment with a specific prepaid card of a type provided by a premises manager, which can be installed for each room or individual of the premises to reduce the burden of telephone users. The purpose is to provide a telephone line.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, a private telephone line according to the present invention is provided by a private manager for calculating a frequency corresponding to use of a private telephone, a television, a washing machine, a refrigerator, a FAX, an AV, an NES, and other devices. Is used to charge off-line telephones, televisions, washing machines, fax machines, and other equipment at hospitals, hotels, offices, and other premises using a specific prepaid card of the type provided by Onhook, Offhook, and Line. polar, for home with a circuit control unit having a ring signal and dial signals such detection, further connection and disconnection of the telephone line, and a card reader unit constituting a power calculation of the type of a particular prepaid de card premises administrator provides A private telephone is connected to an NTT telephone line via a card charging adapter.
[0006]
[Action]
That is, since the above-mentioned configuration is adopted, for example, by inserting a specific prepaid card into a private-room card charging adapter, it becomes possible to make outgoing calls and incoming calls using a private-use telephone set for a private room or an individual, and It is possible to collect a call charge using a specific prepaid card for each telephone (extension telephone).
[0007]
【Example】
In the embodiment shown in FIG. 1, the card system management device 5 that performs frequency subtraction corresponding to the operation of the television 2, the refrigerator 3, the washing machine 4, and the like with a specific prepaid card provided by the premises manager is on-hook and off-hook. A line controller, a circuit controller for detecting the line polarity, ring signal and dial signal, and further connecting / disconnecting the telephone line, and a card reader unit for subtracting the frequency of the specific prepaid card. The private telephone 8 is connected to the NTT telephone line 7 via the card system management device 5 and the private card charging adapter 6. In the figure, 9 indicates a PBX.
[0008]
At the time of implementation, it is also possible to connect the private card charging adapter 6 to the NTT telephone network 10 directly or via the PBX 9 as shown in FIG.
[0009]
The operation of the private telephone line of the above embodiment will be described in detail below.
(1) Idle state / reset state;
In the idle state, a ring signal and a connect command from the card reader are constantly monitored, and a reception mode is activated when a ring signal is detected, and a transmission mode is activated when a connect command is received. In this state, the line and the telephone are not connected.
[0010]
(2) Transmission mode;
When the transmission mode is activated, the operation proceeds in the following order.
(1) Connect the line to the telephone.
(2) The receiver monitors the line until off-hook is detected.
If no off-hook is detected after elapse of 20 seconds, it is regarded as outgoing call cancellation, a hang-up detection notification is transmitted, the line is disconnected, and the system returns to the idle state.
Also, when a break instruction is received during line monitoring, the line is immediately disconnected and the system returns to the idle state. However, in this case, the hangup detection notification is not transmitted.
The off-hook detection is regarded as valid off-hook detection after confirming the off-hook state for 500 ms to avoid erroneous detection due to pulse noise of the line.
(3) The line is monitored until a dialed number is detected.
The end of the dial number string is determined by satisfying one of the following conditions.
-15 digits of the dialed number were detected.
-No dial input for more than 20 seconds.
-Polarity reversal (response of partner) was detected.
If on-hook (dial interruption) is detected during line monitoring, it is regarded as outgoing call cancellation, a hang-up detection notification is transmitted, the line is disconnected, and the system returns to the idle state. Also, when a break command is received, the line is immediately disconnected and the system returns to the idle state. However, in this case, the hangup detection notification is not transmitted.
During the detection of the dialed number, the calling restriction number list is constantly searched, and when the corresponding number is detected, a hangup detection notification is transmitted at that time to disconnect the line and return to the idle state. Similarly, when the number of effective digits is less than three digits (a total of four digits in the PBX mode and three digits in the case of NTT Direct), it hangs up as an error.
This occurs after 20 seconds have passed since the outside line was dialed 0 (after dial detection was completed).
This is to prevent unauthorized use such as dialing a subsequent telephone number.
The polarity inversion and off-hook are detected by checking the progress of the state for 500 ms in order to avoid erroneous detection due to line pulse noise.
(4) The line is monitored until the response (polarity reversal) of the dialed party is detected. After detecting the other party's response, the penalty number list is searched first, and if applicable, "UO CR @" is sent. After 0.5 seconds, a hang-up detection notification is sent and the line is disconnected to enter the idle state. Return. Next, a flat rate (fixed rate) table is searched, and if applicable, the fixed rate is transmitted in the format of “Ux {CR}”. Finally, the area code list is searched, and the corresponding unit charging time is transmitted in the format of “Tx {CR}”.
If on-hook (dial interruption) is detected during line monitoring, it is regarded as outgoing call cancellation, a hang-up detection notification is transmitted, the line is disconnected, and the system returns to the idle state. Also, when a break instruction is received, the line is immediately disconnected and the system returns to the idle state. However, in this case, the hangup detection notification is not transmitted.
The polarity inversion detection is regarded as effective inversion detection after confirming the inversion state for 500 ms in order to avoid erroneous detection due to line pulse noise.
Here, the penalty number list is a kind of transmission restriction number, and indicates a transmission restriction number list to which the other party has already answered when three digits are detected, for example, 115. When such a number is detected, first, several card charges are made once with "UO \ CR \" (penalty), and immediately thereafter, the telephone line is disconnected (call restriction).
(5) Monitor the line until the call ends. The end of the call is detected by polarity reversal (when the other party hangs up first) or on-hook on the calling side. When the end of the call is detected, a hang-up detection notification is transmitted to disconnect the line and return to an idle state.
Also, when a break command is received, the line is immediately disconnected and the system returns to the idle state. However, in this case, the hangup detection notification is not transmitted.
The polarity inversion and on-hook detection are performed by checking the state progress for 500 ms in order to avoid erroneous detection due to line pulse noise.
In any of the above states, if there is no acknowledgment to the transmitted command, it is regarded as a system abnormality, and the line is immediately cut off to return to the idle state.
[0011]
(3) reception mode;
When the reception mode is activated, the operation proceeds in the following order.
{Circle around (1)} After confirming the ring signal, transmit a ring detection notification and connect the line. This causes the phone bell to start ringing. The ring signal is regarded as an effective ring signal in the detection of the first three cycles (about 200 ms) of the ring signal in order to avoid erroneous detection due to pulse noise of the line. If the ring signal is confirmed to be in error, it is determined to be due to pulse noise, and the process returns to the idle state.
(2) The line is monitored until a response (off-hook) of the own station is detected. After the response is detected, a response detection notification is transmitted, and the process proceeds to the next step. If the ring signal is lost before the call is answered (the caller hangs up after canceling), the hangup detection notification is detected for a confirmation time of 3 seconds (because the ring period is 1 second on and 2 seconds off) This prevents erroneous detection.
During this incoming call detection, the control command is not monitored.
(3) Monitor the line until the call ends. The end of the call is detected by the on-hook of the own station (the polarity is not inverted in the case of reception). When the end of the call is detected, a hang-up detection notification is transmitted to disconnect the line and return to an idle state. Also, when a break command is received, the line is immediately disconnected and the system returns to the idle state. However, in this case, the hangup detection notification is not transmitted.
The polarity inversion and on-hook detection are performed by checking the state progress for 500 ms in order to avoid erroneous detection due to line pulse noise.
In any of the above states, if there is no acknowledgment to the transmitted command, it is regarded as a system abnormality, and the line is immediately cut off to return to the idle state.
