The present invention relates to a relay method of an exchange system, and more particularly, to a method for automatically implementing a relay function using a speech synthesis apparatus.

Generally, the exchange system implements the exchange function manually through the transit station. That is, the exchange system connects these calls to the relay station when the trunk line or the internal line is generated, and after the operator checks the call received by the relay station, connects the call to the station or the trunk line.

The switching system also features the ability to record voice messages and automatically respond to simple voice messages when you are away. In this case, the switching system includes a circuit capable of recording and reproducing a voice message, and performs a function of allowing an external or internal subscriber to automatically answer a voice message memorized in a call. At this time, the exchange system records a voice message in a voice message system (VMS), and registers whether or not a call is made to the voice processing device when a call is generated from outside or inside. When a call is generated in the above state, the switching system drives the voice processing device to send a voice message to the calling party.

Therefore, in the former exchange system, it was necessary to perform the exchange function manually after confirming the call received by the attendant one by one. In the latter exchange system, only the automatic answering function of the simple voice message was performed, so the actual call was relayed. The function could not be performed.

Accordingly, an object of the present invention is to provide a method for automatically implementing a relay function using a speech processing apparatus in an exchange system.

It is still another object of the present invention to provide a method for automatically relaying an incoming call by selecting a CO line in an exchange system through a voice processing apparatus.

Hereinafter, the present invention will be described in detail with reference to the drawings.

1 is a configuration diagram of an exchange system having a voice processing device, wherein the control unit 11 controls the overall operation of the exchange system and simultaneously controls the operation of the voice processing device. The subscriber circuit 12 performs an interfacing function between subscribers and the system under the control of the controller 11. The trunk circuit 14 performs an interfacing function with the trunk line under the control of the control unit 11. The switch circuit l3 is connected between the subscriber circuit 12 and the trunk circuit 14 and performs a function of exchanging incoming and outgoing signals under the control of the control unit 11. The buffer 17 is connected to the control unit 11 and buffers the control signals of the audio processing device output from the control unit 11. The control signal includes a reset signal, a start signal, a stop signal, a record / reproduce signal, and the like. The voice synthesis unit 15 is connected to the switch circuit l3, and an operation mode is determined by a control signal output from the buffer 17 to convert the voice signal received from the switch circuit 13 into digital voice data. Synthesized and stored or stored digital voice data is synthesized into a voice signal and output to the switch circuit 13. The voice memory l6 performs a function of storing and reproducing a voice message under the control of the voice synthesis unit l5.

2 is a diagram illustrating a process in which the voice synthesizer 15 performs a recording operation to convert a voice signal received from the switch circuit 13 into digital voice data and then record the voice signal to the voice memory 16. It is shown.

3 illustrates a process of setting a trunk line for performing an automatic relay function according to the present invention.

4, the trunk line ports are sequentially examined to check the presence or absence of the trunk line ring, and when incoming, the ring count of the trunk line port is increased.

FIG. 5 is a diagram illustrating a process of implementing an automatic repeater function according to the present invention. When a trunk line ring is received, it is checked whether the corresponding trunk line is a trunk line set with an automatic relay function. The process of connecting a device to send a guide message informing about the automatic relay function and then forming a call path with a corresponding extension subscriber according to the digit received thereafter.

The present invention will be described in detail with reference to the flowcharts of Figs.

First, when the automatic relay function is to be implemented using the voice message in the switching system, a configuration capable of recording and playing back a voice message for guiding the auto relay should be provided. In the same system as in the first diagram, the voice synthesizing unit 15 and the voice memory 16 implement a recording and reproducing function of the voice message. The voice synthesizer 15 may use “KS5917”, and in this case, may record a voice message for about 30 seconds. The voice synthesizer 15 receives a reset signal, a start signal, The operation mode is set by receiving the stop signal and the recording / reproducing signal. In the recording mode, the voice signal received from the switch circuit 13 is synthesized into voice data and recorded in the voice memory 16. Voice data is accessed from the memory 16, synthesized into a voice signal, and output to the switch circuit 13.

In the case of implementing the automatic relay function using the voice message in the switching system as described above, a process of recording a voice message for implementing the automatic relay function by using a repeater telephone and an automatic relay using the recorded voice message The process of designating the CO line to implement the function, and checking the CO line when the incoming call is detected, outputting the voice message to the CO line when the automatic relay function is set, and then connecting the subscriber and the call path corresponding to the digit received. It consists of the process of forming.

First, a process of recording and playing back a voice message using a relay telephone will be described with reference to FIG. When a specific key signal for setting a recording function is received from the relay phone, the control unit 11 receives it through the subscriber circuit 12 and recognizes that the recording function is selected in step 201. It is assumed here that the specific key is a switch / alarm key. Then, the control unit 11 displays the recording number (recording NO) to the repeater telephone side in step 202, and waits for the reception of the recording code.

In this case, when the recording code is received from the relay phone, the control unit 11 recognizes it in step 203 and indicates that a function of recording a voice message is set in the voice processing apparatus (SYS VMS REC). After that, the control unit 11 controls the switch circuit 13 to form a communication path between the telephone set and the voice synthesis unit 15. In step 206, the control unit 11 returns to the voice synthesis unit 15. After outputting the set signal, a recording / playback signal for performing a recording function is output to set the voice synthesizer 15 to a recording mode. Then, the voice signal generated from the relay phone is converted into voice data by the voice synthesizer 15 and recorded in the voice memory 16 as a voice message for performing an automatic relay function. At this time, the recording of the voice message is performed for a predetermined time through steps 206 to 207, and the recording is performed for about 30 seconds.

When the recording process is completed as described above, the control unit 11 outputs a stop signal to the voice synthesis unit 11 in step 208 to stop the recording function of the voice message, and in step 209 to record the voice synthesis unit 11 Outputs a recording / playback signal for playing back a voice message. As a result, the voice synthesizer 15 accesses the voice message recorded in the voice memory 16, reproduces the voice message, and outputs the voice signal to the switch circuit 13. You will be able to see one voice message.

After recording the voice message as described above, the trunk lines for performing the automatic relay function are designated using the voice message, which is performed in the same process as in the third diagram. In the above process, when an incoming call is received, an automatic relay service function or a general operation is performed. This is because even though a voice processing device is built in and an automatic repeater function is performed, there may be a case where the user does not want to receive such a service. Therefore, in the present invention, if a DISA (DirectInward Station Acces) line is designated for each CO line, the CO lines will be serviced with an auto relay function.

Since the selection of the DISA trunk line is performed in the program mode, when the # key, which is the program key, is received in step 301, the DISA trunk line is transferred to the program mode. When the code for setting the DISA function is generated in the program mode as described above, the code is received at step 302, and control is passed to the DISA set module. In step 303, the trunk line trunk to be set is displayed. Thereafter, when the set key is received in step 304, the corresponding trunk line is designated as a DISA trunk, and in step 305, the next trunk is selected. In this case, if the #key, which is the program key, is received again, the program mode is terminated. Therefore, the program is terminated in step 306. Otherwise, the program is terminated.

When the above process is performed, a flag indicating that the DISA function is set for each trunk line is set, and when the trunk line is generated, an automatic repeater function is performed with reference to the above flag. Therefore, after performing the above processes, when the incoming ring signal is received by the CO line with the DISA function set, the voice processing device operates to perform the relay function automatically.

4 is a diagram illustrating a process in which the control unit 11 inspects the trunk circuit 14 to count whether a trunk line ring is ringing or not. This is a process of checking whether the incoming CO line is a valid ring signal. First, in step 401, the arbitrary trunk line port is checked, and if the trunk line ring is being received, the incoming time count of the corresponding trunk line port is increased in step 402. In step 403, the next CO line is designated to check whether the next CO line is ringing. If the designated CO line is the last CO line in step 404, the process of checking the CO line is terminated.

Therefore, if the CO line monitoring process for continuously detecting the CO line ring is performed as described above, each time the ring signal is detected to the corresponding CO line port, the count value assigned to each CO line is increased. When the count value is greater than or equal to a certain value, the trunk line ring is considered detected.

If it is regarded as the incoming call of the ring by performing the CO line monitoring process as described above, it performs the same process as the fifth diagram to perform the auto relay function by voice message.

The control unit 11 monitors the CO line port at a predetermined cycle by performing the same process as that of the fourth diagram, and when a CO line ring signal is detected at a certain CO line port for a predetermined time, the controller 11 recognizes this at step 501 and the CO line ring is received at step 502. Check if the CO line port is DISA. That is, when the CO line ring is received, the control unit 11 performs the same process as that of the third line to check whether the flag indicating that the CO line is the DISA CO line is set. Therefore, if the flag is set in the corresponding trunk line in step 502, the corresponding trunk line port is not a DISA trunk line, and thus proceeds to step 520 to perform a general trunk line call process. That is, in this case, a ring signal indicating that the trunk line ring has been received is delivered to the relay station or the designated station and the call is processed in a general manner.

However, if the CO line is a DISA CO line in step 502, the CO line is made busy in step 503 so that other subscribers cannot respond and waits for a second time in step 504. At this time, the second time is about 5 seconds, and in this standby state, the calling party hears the ring back tone supplied from the local exchange. When the second time has elapsed, the controller 110 recognizes this in step 504, and the controller 11 turns on the corresponding trunk line relay of the trunk circuit 14 in step 505, and controls the switch circuit 13 in step 506. A transmission call path is formed between the trunk circuit 14 and the voice synthesis unit 15, and at the same time, a reception call path is formed between the trunk circuit 14 and the DTMF receiver. This is a process in which the control unit 11 reproduces the voice signal for performing the auto relay function by using the voice message recorded by the corresponding trunk line, thereby taking a ready state for receiving a digit received from the corresponding trunk line. Becomes

In step 507, the voice processing apparatus is checked for existence. If the voice processing apparatus is present, the playback mode signal and the start signal are output to the voice synthesis unit 15 in step 508. Then, the voice synthesizer 15 accesses the voice message stored from the voice memory 16 by the reproducing command received through the buffer 17 to reproduce the voice message, and then switches the circuit 13 and the link circuit. A process of outputting a voice signal for implementing an automatic relay function to an outgoing subscriber of a corresponding trunk line by outputting through a transmission line formed through 14 is performed. The recording of the voice signal is performed in the same process as the second diagram, and it can be seen that the recording time is about 30 seconds.

After reproducing the voice signal, in step 509 to step 510, it is checked whether a DTMF signal, which is telephone number information, is received through the received call path formed within the first time. At this time, since the recording time is set to about 30 seconds, the first time is also set to about 30 seconds. Therefore, when the DTMF signal, which is the telephone number information, is received from the corresponding trunk line within the first time, it is checked in step 511 whether the DTMF signal received is the extension number, and if it is the DTMF signal of the extension number, the switch circuit 13 in step 512. By controlling the control, a call route is formed between the corresponding station and the trunk line to perform an automatic relay function. At this time, the control unit 11 outputs a stop signal to the voice synthesis unit 15 regardless of the state of the first time when the DTMF signal is received, thereby causing the voice synthesis unit 15 to reproduce the voice message. Stop at that point.

However, if the received digit is not the extension number while the voice message is being reproduced or completed in step 511, the process proceeds to step 515 to initialize the switch circuit 13 and the trunk circuit 14. Disconnect In step 509, if the digit is not received within the first time, the process proceeds to step 514 to determine whether the digit is received within the third time. Here, the third time is 10 seconds, and if the digit is not received during the first time, it means that the third time is further waited to wait for reception of the digit. In other words, even after waiting for about 10 seconds after the recording of the recorded voice message is completed, if there is no reception of the digit, the currently connected trunk line is released. If there is no voice processing device in step 507, the dial tone is supplied in step 513, and then the corresponding trunk line is released by performing steps 514 and 515.

As described above, the voice processing apparatus is built into the switching system, and the voice processing apparatus records the voice message for implementing the automatic repeater function, so that the recorded voice message is reproduced when the incoming call signal is received. It can implement the relay function automatically, and can freely record the voice message to improve the service of the automatic relay function, and also can set the function for the automatic repeater implementation for each CO line for efficient system There is an advantage that can be realized.
