Abstract

PURPOSE:To execute proper management of telephone set by changing automatically the initial service class to the other class when the budget is consumed out. CONSTITUTION:The budget stored on a magnetic card and in a storage RAM is displayed while being decremented at each calling. On the other hand, the service class of a connected telephone set is also preset to the magnetic card and the storage RAM, a transmission signal is collated and discriminated at calling, and if a signal other than the designated number is transmitted, a line switch RL connected in a loop to a telephone line is closed for a prescribed time so as to limit calling. Thus, if the budget of a talking charge is decreased into 0, the service class is changed automaticaly from the service class used up to now into the other class so as to limit the calling.

Description

[Detailed description of the invention] The caller reads the dial impulse number sent by a multi-frequency code, and uses a call charge meter (or a call charge meter for calls exceeding a certain time) that starts operating when the caller responds by changing the line polarity. The budget for the magnetic card or internal memory 1 (・A, M is subtracted (displayed as -7) for each outgoing call. On the other hand, the 9-1 bis class of the connected telephone also uses this magnetic card. Alternatively, it can be set in advance in the memory It AM, and at the time of making a call, the transmitted signal is compared and determined, and if a signal other than the specified number is transmitted, the line/switch (RL) connected in a loop to the telephone line is activated for a certain period of time. , and has the function of restricting outgoing calls.When the above-mentioned call fee subtraction (currently the budget for the number of calls exceeding a certain amount of time) reaches O, the service class is automatically changed from the previous service class. This is a device that can change the class to another class and restrict outgoing calls.

Conventional call regulation devices and call rate/call time measurement devices had functions such as simply regulating long-distance calls and acting as a rate side, but they did not have a function that could automatically change the service class when the budget was reached. For this reason, it was difficult to know when the call charges exceeded the budget, and it was difficult to properly manage the telephone equipment.However, in consideration of the above points, the present invention strictly restricts usage within the call charge budget and long-term calls. Execute accurately (7 Uru telephone bill meter (
To provide a telephone call management device with a number of calls exceeding a certain period of time.

The present invention consists of a device including the following circuit shown in FIG.

The main control unit of this device controls each circuit, such as changing the execution service class of Q when the budget held in the magnetic card or storage RAM reaches O.

Q, Knee Check the identification of the transmitted signal at Q, and if a signal other than the callable number stored in Q5 is transmitted, R and L (line switches) in Figure 2 are kept open for a certain period of time. A circuit that releases lines.

Q. In Fig. 2, when the hook is hooked, the input current flows through either 1, 1, or FT to determine the line polarity and determine the input direction. When there is a response from the other party, the input direction is reversed (11) and the polarity is reversed, which is used as an operation start signal for the toll side, etc.

Q3 A circuit that identifies the outgoing signal and checks it against the callable station number of the active service class.

Q: A circuit that applies the signal identified by Q to timer data to register call charges or set call time.

Q6 Memory RAM circuit of this device, including call charge registration service class, number of outgoing calls, number of calls over a certain period of time, deduction and addition, speed dial data, etc.

Q6: A clock circuit that displays the month, day, hour, minute, day of the day, etc., and also sets the time to change the execution service class at a fixed time.

Q79 A buzzer circuit that outputs an alarm every minute when measuring call time and when registering charges.

Q: A data input circuit that manually enters Q's fee budget, callable numbers, etc.

Q, ,: A circuit that measures and displays call time at Q.

Q,...: A circuit that displays the execution service class of Q.

Ql: A circuit that displays numerical data such as call charge budget, call charge count, number of calls, etc.

Q, ,: A magnetic card unit that reads and writes the call charges, execution service class, etc. in Q.

Claims (1)

[Claims] 1. In advance, the service class of the telephone connected to the magnetic card or internal storage AM in the device, the cumulative call fee subtraction (or the budget for the number of calls exceeding a certain time), and the semi-special grade call Set the available station numbers, etc., read the partner station number sent when making a call, check it with the service class designated number, and release the telephone line if a number sent that does not match the available numbers is sent. The telephone charge meter has the function of restricting outgoing calls for a certain period of time, and starts operating in response to a response signal from the called party after becoming ready to make a call. ). This registration circuit has the function of subtracting from the budget (2) and displaying the count, and when the budget reaches O (7), it is possible to automatically change the initial service class to another class. A telephone call management device with a charge meter (number of calls over a certain period of time). 2. A telephone call control device according to claim 1 that reads and identifies the other party's station number sent by the caller. , a circuit that performs a check against a preset designated number that can be called, and if there is no match, limits outgoing calls by keeping a line switch loop-connected to the telephone line open for a certain period of time.
