Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a control method for a communication control device that allows an appropriate response without enlarging the voice information storage memory of the communication control device when making a voice response from an information center to a terminal.

The basic configuration of an information processing system in which multiple terminals and an information processing center are connected via a public switched telephone network and perform data transmission is shown in Figure 1, and operates as shown in the time chart in Figure 2. ing. Terminal A, which is commonly known as a data telephone with a telephone and an automatic tape (card) reader, and terminals B and C, which are called pushphones, are connected to the public switched telephone network.
It is configured so that it can be connected to the information processing center DPRC via EXC. The operator at terminal A first picks up the telephone handset. FIG. 2A shows the operation of terminal A, and HOF shows when the handset is lifted (hook-off). The operator hears the dial tone from the telephone exchange network EXC and
Dial the subscriber number of the information processing center DPRC. In the information processing center DPRC, the network control unit NCU operates first (Figure 2B) and transmits to the MDM (modulator/demodulator) (Figure 2C), so the Ci signal turns on and is transmitted to the communication control unit CCU (Figure 2C). Figure 2D). The communication control unit CCU now preferably informs the terminal operator that a connection has been made to a mechanically automated processing location, but normally it simply sends back a ring back tone. After the ring tone T (for example, 2 to 3 seconds), the center DPRC establishes a hook-on state to notify the various circuits within the center and the operator that the call has arrived. When the operator presses the transmit button on the terminal after the ringer is turned off, the terminal generates an ENQ signal when it is ready to transmit and sends it to the center. When the center is ready, it returns a response signal ACK. Next, the operator sends a data statement (TEXT). Data received response signal
When ACK is returned, send data end signal EOT,
Wait a while and then turn off the handset. The electronic computer CPU also shuts down and data transmission ends. The disadvantage of this case is that if the terminal operator is not sufficiently trained, the information processing center DPRC
If the center is not aware that the subscriber number was dialed to another location by mistake, or if the center is out of service for some reason, invalid data may be sent. Furthermore, even if a telephone subscriber who is supposed to talk to a certain person dials the center by mistake, there is no voice response from the center, so the line is held inactive for a long time, and the terminal that wants to send data is forced to wait. Therefore, if a voice response is made from the center, the above-mentioned drawbacks can be alleviated considerably, so it is possible to divide the sentence into short syllables, record them on a voice drum, etc., and synthesize them according to instructions from a computer. considered,
It is put into practical use in telephone calculation centers, etc. Since all of this equipment operates according to instructions from an electronic computer, the load on the computer is large, making it extremely large and expensive. It is also possible to introduce tape recorders, but this may be fine if there is a single line, but it would be inappropriate to respond to multiple lines as it would be necessary to prepare a large number of tape recorders.

For this reason, the inventor of the present invention has proposed that a voice response device be provided in a communication control device in an information processing center and that its operation be started in response to a command from a computer. FIG. 3 is a block diagram showing the internal configuration of the communication control device and the modulation/demodulation device. In Figure 3, the modem device MDM and the network control device NCU
and the modem device MDM, and when a voice response is to be made from the center, the changeover switch is changed according to a command from the communication control device CCU, and the network control device NCU and the voice adapter are connected. Communication control unit CCU
The LCF inside is a line connection mechanism that connects line adapters LA0, LA1, etc. equal to the number of lines and voice adapter VOA.
It is formed by 0, VOA1,... PU is a general-purpose microprocessor, MEM is a memory that stores microprocessor operation programs and line control information, IF is an interface, and VOM is a voice memory that stores encoded voice information in units of messages, for example. . When the computer CPU detects an incoming call to the information processing center, it activates the microprocessor PU, converts the audio information read from the audio memory VOM into audio in the audio adapter VOA, and sends it out.

The purpose of the present invention is to further improve the operation of such a communication control device, and to provide a control method for the communication control device that allows audio information read from a computer and audio information on the communication control device side to be edited and sent out. It is about providing.

Examples of the present invention will be described below. Figure 4 is a diagram showing an example of address assignment and stored information in the memory MEM in Figure 3, and Figure 5 is an example of messages stored in the voice memory VOM in Figure 3 and commands to select them. FIG. First, in Figure 4, the address is in hexadecimal code
It is indicated by "0000" to X "FFFF". LCW indicates a line control word, and 16 lines LCW0 to LCW15 use 256 bytes from X"0000" to X"00FF". Each line control word LCW consists of 16 bytes, the contents of which are shown on the left. The 0th byte LMD specifies the line operation mode, line connection adapter type, etc. in the initial settings from the computer, and the 1st byte PCD is a byte that specifies the line transmission control procedure, similar to LMD. The second byte, PYN, indicates the machine number on which the line adapter and audio adapter are installed. The third byte, CMD, is a byte that stores the line command code and is rewritten every time a command is issued from the computer, and the fourth byte, DAT, is used to transfer line transmission and reception data to the computer and line connection facility LCF. It's a battle.

Next, the control program CTP is stored in addresses X “0100” to X “FEFF”, and the remaining
256 bytes at addresses "FF00" to X "FFFF" are allocated as hard registers. X
Line connection mechanism from “FF00” to X “FF7F”
Assigned as LCF control register, R to one line
Since eight addresses from 0 to R7 are assigned, various line connection adapters are controlled using a maximum of eight registers. The definitions of R0 to R7 are determined for each line connection adapter LA. Then X
“FF80” to X “FFFF” are microprocessors
Used as a control register for the PU and interface IF.

The voice memory VOM in Figure 5 contains message A,
Multiple messages such as message B,... are stored, and the command to select each message is given by the command CMD on the communication control unit CCU side as shown on the right.
1, CMD3, and computer side command CMD2. SCH indicates one subchannel of a computer, and DISK indicates, for example, a disk in the computer, in which encoded audio information (product name, proper noun, etc.) is stored, and the number of bytes is arbitrary. Note that commands CMD1 and CMD3 are VA0 to
It is formed of 6 bytes VA2, VB0 to VB2, and specifies a message in the voice memory VOM. VA indicates the start address of the message, and VB indicates the number of bytes of the message. In FIG. 5, command CMD1 indicates that message B and message X can be selected, and command CMD3 indicates that message A can be selected. In FIG. 6, which shows the configuration of the audio adapter VOA, LNB is a line number setting device, and LNS is a line number selection device. Determine by comparing with the setting number. RND is a register number decoder that decodes the number information of the control register of the audio adapter in the information on the address bus B1, and selects a predetermined register RG0 to RG7.
That is, when the computer sends the voice response message selection command CMD1, the communication control device
The processor PU in the CCU uses the command byte of the line control word LCW of the corresponding line in the memory MEM.
Store the selection command in CMD. The control program transfers the data specified by the command from the computer byte by byte, and reads the line control word.
Store in DAT byte. Next, the control program
The first 3 bytes of CMD byte are used as audio adapter.
Set in memory address register MAD of VOA. The remaining 3 bytes are set in the byte number register BYT of the audio adapter VOA. At this time, the register number is set by the output of the register number decoder RND.
RG1 to RG6 are selected and each byte is stored. That is, signal S2 indicates that register RG1 has been selected, signal S3 indicates that register RG2 has been selected, and so on. The input signal W is operated by the AND gate A9, and information on the data bus B2 is set in bits 0 to 7 of the byte register BYT. The write signal W is calculated by the AND gate A1 on the signal lines C1 and C2, and indicates that the information on the data bus B2 is being sent from the processor. Next, the signals S3, B2 data, and write signal W are operated by the AND gate A10, and information on the data bus B2 is set in 8 to 15 bits of the byte register BYT. Similarly, the signal S4 is input from 16 to 16 of the byte register BYT by the AND gate A11.
Set the information to 23 bits. Furthermore, information on the data bus B2 is set in bits 0 to 7, bits 8 to 15, and bits 16 to 23 of the memory address register MAD via AND gates A12 to A14 by signals S5 to S6. Then register RGO
is selected and emits a signal S1, and the AND gate A6,
Latch circuit FF2 is set via OR gate OR2. The output of latch circuit FF2 is audio memory VOM
Since this is the start signal for making the first data transfer request to the memory address register MAD, the address of the memory address register MAD enters the voice memory VOM via the bus B3, and the message at the corresponding location is placed on the bus B4. Store each byte in the far register VDB. The D/A is a digital to analog converter, which converts it into audio information and sends it to the changeover switch SW. When one byte of audio information is taken out from the audio memory VOM, the number of bytes in the byte register BYT is decremented by 1, and the address in the memory address register MAD is incremented by 1. Also, when the information in the audio memory VOM that has been read once is enabled, the signal line C5 becomes "1" and the AND circuit A8 generates the signal S12 and the latch circuit
FF2 is reset and latch circuit FF1 is set. The output of latch circuit FF1 is OR circuit OR1
The converter D/A is controlled via the converter D/A to start the audio conversion operation. The data from the buffer register VDB and OR circuit OR3 is read and converted into an analog signal using the sampling period of the oscillator OS. When the conversion is completed, the signal S13 is obtained and the AND gate A5,
Latch circuit FF2 is set through OR circuit OR2. Therefore, a second data transfer of the audio memory VOM is required. Audio information converter D/A again
is reached, the next sound is output, and the process is repeated. When the number set in the byte register BYT becomes zero, the zero detector ZR generates the signal S10, so the AND circuit A5 is closed and no further data transfer can be requested, and the interrupt request signal generating circuit ITR is connected to the processor PU. An interrupt request signal is issued to the Furthermore, DV
is a driver for driving the changeover switch SW shown in FIG. 3 when the converter D/A operates. When the processor PU recognizes an interrupt from the audio adapter VOA, if the byte counter of the subchannel SCH in Figure 5 is not zero, it further transfers 6 bytes of data between computers and transfers the data to the audio adapter.
Set in registers MAD and BYT of VOA. The audio adapter VOA performs audio conversion in the same manner as described above. If the byte counter of the subchannel SCH is zero, the processor PU reports termination to the subchannel SCH, and therefore sends the command CMD2 shown in FIG. 5. Next, the processor PU stores the command CMD2 in the command byte of the line control unit LCW, receives the first byte from the computer, and directly sets it in the register DTB in the audio adapter VOA. The digital/analog converter D/A receives the information stored in the register PTB according to the sampling period of the oscillator OS, and at the same time requests the processor PU for the next data transfer via the signal line S11 (interrupt request signal generation circuit (using ITR). The processor PU determines whether the byte counter of the subchannel SCH is zero. If it is not zero, the next data transfer request is made to the computer and the data is retrieved. The data is set in the register DTB and the voice is converted as described above. If the byte counter is zero, the completion of command CMD2 is reported.
Subchannel SCH starts executing the next command CMD3 upon receiving an instruction from the command chain.
At this time, the original operation of the voice adapter VOA is performed, and the voice response continues until the byte counter of the subchannel SCH becomes zero. In FIG. 6, bit D7 of bus B2 is a command bit for the voice adapter VOA to convert data from the voice memory VOM to give a voice response, bit D6 is a command bit for converting data from the computer, and D5 is a command bit for converting data from the computer.
is a bit that instructs the end of the data conversion operation from the electronic computer. Further, FF3 is a latch circuit which is bitted by bit D6 when it is in operation.

In this way, according to the present invention, information different from the content of the communication control device is stored in the voice information storage device on the computer side, and since the memory of the computer usually has a large capacity, it is often used as a product name. Since infrequent information can be stored, it is only necessary to set the order of operations between information read commands in the communication control device. Since the voice memory of the communication control device is not made too large and the operation speed is not reduced, the voice response of the communication control device can be performed appropriately.
