The present invention relates to an apparatus for servicing a wake-up call by interlocking by interworking with another private exchange (PABX, etc.) and an E / M (Ear / Mouth) dedicated line (Tie Line). Provides high quality wake-up calling function by sending multiple messages by installing E / M tie line between private exchange with built-in upcall and exchange without built-in wake-up call. The present invention relates to a wake-up call service control circuit and method.

In general, the wake-up call function is one of several service functions on the exchange that can notify the subscriber's appointment time at the scheduled time or wake up the subscriber who is sleeping at the scheduled time. The wake-up call function is connected to an E / M dedicated line with a switch (PABX) to provide a service according to the wake-up call to an exchange extension subscriber by interworking. A general block diagram of an E / M dedicated line is shown in FIG. 1. The E / M dedicated line is divided into a voice path and a signaling path, so that a call is made through voice paths T and R, and a signal is made of signal paths E and E. If there is an input for calling, the other station can call the subscriber through the operator, or can call the subscriber by dialing the subscriber number directly with a pulse and the call is always connected. When a seizure signal (hereinafter referred to as GND) enters the E line, the ring and the GND detection circuit detect it and operate the loop and the occupancy relay to transmit an occupancy recognition signal to the M line. After receiving the recognition signal from the other station, send pulse through E-line or connect the call exchanger with the telephone line. The recovery signal of the calling party is to open GND on the E line, and the recovery signal of the called party is to send the Release Backward signal to other stations by opening GND on the M line.

The output call is made to occupy the E and M dedicated lines when the station subscriber turns the ID number of the E and M dedicated lines, and the operator can also occupy the E and M dedicated lines. The occupancy of the other station becomes the occupying signal of the other station by sending GND signal to M line when the relay is operated by giving data to the E, M dedicated line from the microcomputer device.

After receiving the occupancy signal, the other station sends a recognition signal to the E-line, and after detecting the signal, connects the operator to the telephone line or restores the operation of the relay to the digit received from the subscriber. Sends a pulse of the dial signal to another station.

After receiving the pulse, if the receiving party of the other station is idle, the other station sends the ring back tone to the subscriber or the operator. In this case, when the called party answers, the call is made and the wake-up message can be received.After the call, the recovery signal of the calling party recovers the relay and the M line removes the GND, and the called party recovery signal removes the GND from the E line of the other station. Just do it.

As described above, a wake-up signal is sent through the E / M dedicated line to wake up the desired subscriber to make a call through the call path.

In the conventional exchange, the wake-up call has been made through the E / M dedicated line at the time of reserving the reserved time by automatically reserving the time when the subscriber wakes up and calling the current time.

However, the message source is limited in the system having the wake-up call function. For example, if a large hotel has a private exchange with a wake-up call function in a hotel where guests with multiple languages are staying or live in different countries, the message source may be one or two languages ( It is limited to English, Japanese, and Korean), and it has caused distrust from subscribers due to the problems of not being able to deliver the message to all the countries and confirming the call result according to the wake-up call.

Accordingly, an object of the present invention is to provide a control circuit capable of distinguishing and serving a plurality of messages in various languages by interlocking signals by connecting an E / M dedicated line with a private exchange or a non-embedded exchange having a wake-up calling function. have.

Another object of the present invention is to add a console device of the printer and monitor to easily modify the various parameters of reservation, change, cancellation, check the wake-up call service results, print the call results to inform the subscriber and respond until The present invention provides a method of performing a high quality wake-up call function by allowing recall.

FIG. 6 is a flow chart of reservation, modification and cancellation and attempt and retry of a wakeup call different from the assignment of FIG. 5, in which the subscriber ST1 of the private exchange 70 receives the wakeup call service. Occupying the lines 3 and 4, the microcomputer 50 checks the occupancy state and sends a recognition signal to the E / M dedicated circuit 60.

That is, the GND / dial pulse detection circuit 280 detects the occupancy state through the overvoltage protection circuit 270 through the E / M dedicated lines E and M lines 3 and 4 of FIG. The microcomputer 50 recognizes the signal through the microcomputer 50 and transmits the occupation signal to the relay control circuit 380 and the scissor / dial pulse transmitting circuit 285.

When the signal dialed from the subscriber ST1 in the process (6b) is input to the E / M dedicated circuit 60 through the private exchange 70, the GNG / dial pulse detection circuit through the overvoltage protection circuit 270 of FIG. At 280, the dial is detected and input to the microcomputer 50 through the multiplexer 290, and at the same time, the dial signal is processed by the DTMF transmitter / receiver 40 of FIG. 2 and input to the microcomputer 50. At this time, the microcomputer 50 switches between the extension number (EXTN #) corresponding to the hotel's telephone number on the RAM and the extension number (EXTN / ID) corresponding to the hotel's room number. Check it. Here, when there is no EXTN # and EXTN / ID to be switched, in the process (6n), the microcomputer 50 controls the switching network 10 to connect a path to receive the tone supply from the tone supply unit 30, and the error tone is changed to E / N. Through the M dedicated circuit 60 to be sent to the subscriber (ST1) of the private exchange 70. After checking whether the microcomputer 50 releases the E / M dedicated line lines 3 and 4 in step (6V), the E / M dedicated line (E, M) of the E / M dedicated circuit 60 in step (6w). ) Initialize lines (3, 4) and complete the service.

However, when the telephone number and room number input in step 6c are present in the conversion table, the reservation time desired by the subscriber ST1 in step 6d is set to the E / M dedicated circuit 60 and the DTMF transmitter / receiver 40. If you want to cancel the reservation from the microcomputer 50 in the process of (6e), check whether the reservation is made in the reservation table in the process of (6f). Delete the phone number (EXTN #) and room number (ID) on the reservation table. However, when the reservation table is not reserved in step 6f, it is checked in step 6g whether the dial number and room number entered are present in the retry table.

When the retry table is in the (6g) process, the phone number and room number are erased, and in the process (6k), the microcomputer 50 controls the switching network 10 to hear a confirmation tone and then, from the process (6v). Falls out.

When the reservation is not canceled in step (6e), it is checked whether the time to be input in step (6i) is an accurate time within the 24-hour period, and in step 6l, the message of the subscriber ST1 is sent to the E / M dedicated circuit (60). And the DTMF transmitter / receiver 40 and receive it from the microcomputer 50, and check the message message identifier of the subscriber's language used in the microcomputer 50 in the process of (6m).

If the ID of the message received in the above process is the wrong data, the error tone is connected in step (6n), and the release of the leased line by the other party is checked in step (6v). After releasing from the M dedicated circuit 60, in the process (6x), the dedicated line service table is initialized, and the services of the corresponding E / M dedicated lines (E, M) lines (3, 4) are terminated.

If the message ID is correct in step (6m), check if there is a telephone number and room number (EXTN # / id) in the reservation table in step (6o). Since only one reservation can be made to the subscriber, the state of the reservation data is already changed, and the connection state is output to the printer or monitor of the console unit 80 in step 6s. If it is not reserved in step (6o), it is empty. In step (6p), the telephone number and room number are reserved in the reservation table as data, and in step (6q), the printer or monitor of the console unit 80 is monitored. After making a reservation or change in the reservation table, connect the confirmation tone (6t).

After the confirmation sound is connected and the other party waits for (6u) process to release the leased line and releases it in (6v) process, it releases the leased line in the E / M dedicated circuit 60 in the process (6w) and the E / M After the service table of the dedicated lines (E, M) lines (3, 4) is initialized in step (6x), the service of the lines (3, 4) of the corresponding E / M dedicated lines (E, M) ends.

If the retry entry exists in the retry table in FIG. 5 (5e) and the retry entry is attempted, when the microcomputer 50 outputs the table data to the relay control circuit 380 in step 6y, the E / M dedicated circuit 60 The line GND of " low ", i.e., " low " the M line 4 of the E / M exclusive lines E, M, 3, 4 of FIG. Wait for the occupancy recognition signal input through

If the microcomputer 50 does not recognize the occupancy in step 6z because there is no recognition signal, the attempt and retry data of the wake-up call is registered in the retry table for retry in step 6K, and then the above procedure of FIG. Return to (6v), (6w) process, if occupancy is recognized in (6z) process, check whether the attempt to wake-up or retry in (6A), if it is an attempt to console the "try" state in (6J1) Output to the printer and monitor of the unit 80, and in the case of "retry", output the printer and monitor to the retry state in the process (6B), and then try and retry in the (6C) process in the microcomputer 50 The stored telephone number data is sent to the DFMF transmitter / receiver 40 to automatically dial DTMF transmission.

If the response signal is received by the microcomputer 50 in step 6D within the predetermined response time with respect to the dial in step 6c, and the response signal is received by the microcomputer 50 (6E), the printer of the console unit 80 and Print the connection and response status of the message to the monitor, return to the above (6V) process in Fig. 6 (b), wait for the other party to release the E / M dedicated line (E, M) line (3, 4) When released, the dedicated line of the E / M dedicated circuit 60 is released, the dedicated line table is initialized, and the corresponding E / M dedicated service ends.

However, if there is no response sound until the response waiting time in step (6D), check the elapse of a predetermined time in step (6F), check whether the last recall in step (6G), and in the retry table at the last recall In the process of (6H) without registering, the wake-up state is output to the printer and monitor of the console unit 80, and is left as a list for confirmation to the subscriber later, and the process is not the last recall in the process (6G). In this case, the process registers in the table in step 6J2 and outputs the non-response state to the printer and monitor of the console unit 80, and registers in the recall table in process 6I.

If the E / M leased lines (E, M) lines (3, 4) are released, after confirming that the other party releases the leased lines in the process (6V) of FIG. 6 (a), the service is initialized and the E / M leased lines (E M) Ends the wake-up call service on lines 3 and 4.

After the console service table of the MICOM 50 is initialized and ready to receive a command, when the command comes in, it checks whether it is a string or a string in step (7a) and wakes up from the console unit 80 when the digit is a number. It handles upcall reservation, change and cancellation, and if it is a string, it processes the command.

If the sequence of numbers in step (7b) checks whether the number sequence received in step (7b) is a telephone number (EXTN #) and a room number (EXTN / ID) in the conversion table of the microcomputer 50, if not (7r) In step), the phone number and room number are displayed as an error on the monitor of the console unit 80, and in step 7s, the monitor service table of the console table is initialized and then fed back for the first time. However, when there is a telephone number and room number entered in the conversion table in step (7b), when it is checked in the reservation table in step (7c), the message name reserved in step (7d) is displayed, If it is not reserved, it receives the corresponding message number and checks whether it is a built-in message or a correct message according to the type of each language of the message source unit 20 in step (7f). Display the number of the error on the monitor of the console unit 80, initialize the monitor service table in the step (7s), and cancel (clear ID) in the process (7g) when the message number purified in the step (7F). Check if it is necessary.

When the ID is not deleted in step 7g, the reservation table is checked in step 7h to check whether the reservation time is set in the reservation table. If the reservation time is reserved (7i), the monitor of the console unit 80 displays the reservation time, and if the reservation is not made, the time is reserved in step (7i). Check whether the time is within 24 hours in the process of 7k). At this time, if something else is already reserved in the reservation table, change the phone number and room number reservation data in the reservation table in step 7m and output the change status to the console unit 80 in step 7n. In step (7n), the reservation is made in the reservation table. In step (7V), the reservation status is output to the monitor and printer of the console unit 80. Then, the console service table is initialized as in step (7s). .

However, when the digit is not a number in step (7a), the input command is analyzed in step (7w) and changed to each function state, and when the error state is in step (7o) (7p), the monitor of the console unit 80 is moved. Displays that the input command is an error and initializes the monitor service table in step (7g).
