Abstract

PURPOSE:To output an incoming rejecting signal when a specific local business work is on business, by providing a means to deliver a prescribed incoming rejecting signal to a communication circuit to show that the reception is temporarily impossible for the incoming although a terminal device is normal. CONSTITUTION:When a special local business work is performed, a command switch 9 for control not-ready CNR state is turned on. Thus a CNR state command is delivered to a communication control part 5 from a system control part 8, and then an incoming rejecting signal is delivered from the part 5. Then a call progress signal is transmitted to the calling side from a circuit connecting part 7. As a result, the calling side knows that the terminal device of the remote side is under a busy state and therefore transmits no document information. Thus it is possible to perform a special local business work through a terminal device for document production communication.

3, the bootstrap ROM 81 side is selected immediately after the power is turned on.

Incidentally, this system control section 8 also constitutes an incoming call rejection signal output means, the details of which will be described later.

Then, this system control unit 8 controls O8. File maintenance program, word processing program, display output program, printer output program, CC, U message sending program.

The entire system is controlled based on the CCU message receiving program, self-diagnosis program, etc.

The functions of each of these programs are as follows.

(a) O8: Mainly task execution management, file management, and Ilo control.

(b) File maintenance program: Mainly input/output of stored information to the external storage unit 4, conversion of stored information into a file, and file management.

(b)) CCU message receiving program: Sends received document information to the output unit 6 or external storage unit 4.

(h) Self-diagnosis program: Diagnosis of the entire system and each part.

Here, O8 will be explained. This O8 is capable of multitasking control and has a resident (resident process function), meaning that a certain process can be embedded in the O8, and that process (task or job) and another process are executed alternately. It has a function that can be controlled.

In this example, O8 is Digital Research (Digital Research).
MP developed by ital Re5each)
/M (Multiflow Monitoring Control Programming).

This MP/M is an upper operating system for CP/M ("Control Program for Microprocessors") developed by the company, and is capable of multiple users (multiple terminals) and multiple programming.

The basic system of this MP/M has a configuration as shown in FIG. XDO8 is the core of MP/M, and B
DO8 manages disk files and each console, and XIO3 manages actual input/output.

In addition, in MP/M, a program called a resident system process can be made to reside in memory, and a program created by the user can also be made to reside in this resident system process, and it is possible to decide whether or not to make it resident. is performed during system generation. In this embodiment, the CCU message receiving program is incorporated into the resident system process during generation.

Other details are left to the explanation in the MP/M User's Manual published by Digital Research.

In this system control unit 8, programs such as the O8 and 7 aisle maintenance program, food processing program, display output program, printer output program, CCU message sending program, and CCU message receiving program are stored in the external storage unit 4. It is stored on a floppy disk.

Then, when the power is turned on, the bootstrap ROM 81 is controlled by the memory control circuit 83, and O8, the file maintenance program, and the CCU message receiving program are loaded into the system area of the RAM 82 based on the bootstrap stored in the bootstrap ROM.

In addition, other programs can be run on the keyboard 1 of the input section 1.
By inputting the file name of a program by operating the 0 key, the program with that file name is read out from the floppy disk to the non-resident program area of the RAM 82 based on O8, and control is performed based on that program.

In this way, the received document information is transferred to the output section 3 or the external storage section 4.
By having a CCU message receiving program output to the computer and a program capable of alternately controlling the execution of a plurality of programs resident in the RAM 82, the CCU message receiving program can be executed in parallel with the word processing program.

As a result, even if document information is received while the word processing program is running and the document creation task is being performed, the execution of the word processing program and the CCU message receiving program can be controlled alternately. The received document information can be output to the output section 3 or the external storage section 4 for recording or storage without interrupting the process.

The CNR status indication switch 9 is an incoming call rejection signal output command means for instructing the incoming call rejection signal output means described below to output an incoming call rejection signal, and is turned on when instructing the output of the incoming call rejection signal. .

Next, details of the configuration of the incoming call rejection signal output means according to the present invention will be explained.

First, since the document creation communication terminal device in this embodiment is connected to the digital exchange network service as described above, the terminal device (hereinafter also referred to as rDTEJ) and the line connection device which is the line connection section 7 (hereinafter referred to as rDCEJ
(also referred to as CCITT Recommendation X, 2)
1, and the communication control section 5 and line connection section 7 are configured to satisfy this requirement.

That is, first, the names of interconnection circuits and their meanings are shown in Table 1.

Processing such as calling, disconnecting, and recovering 2 incoming calls is performed by controlling this interconnection circuit (signal line). For example, calling in the case of an address call is performed in the sequence shown in Figure 7. It will be held in

In addition, the line connection equipment (DCE) is as follows (11-y
It is configured to satisfy (3).

(1) Ready state When the circuit T is "1" and the circuit C is in the r OFF J state, the circuit R is kept "1" and the 9 circuits are kept "OFF".

(2) UNR (7 UNCONTROL NOT READY) status.

When circuit T is "O" and circuit C is r OFF, J, if there is an incoming call, this will be communicated to the DTE, but this state will be detected, circuit R will be set to "1", and circuit engineering
- OFF j, and sends a message "Connection not possible due to call progress signal" to the calling party.

(3) CNR (Control Not Ready) state When circuit C is OFF J and "1" and "0" are being alternately transferred to circuit T in bit units (see Figure 8). , when there is an incoming call, the incoming call is displayed, but this state is detected and the circuit R is set to "1" and the circuit L is turned OFF.
j, and also sends a call progress signal ``Call Rejection'' to the calling party.

Therefore, in this embodiment, when the CNR status command switch 9 is turned on, the system control section 8 causes the communication control section 5 to place the interconnection circuit in the control not ready state shown in FIG. CCU CN for
R state command ratio is input, and the communication control unit 5 sets circuit C to r OFF J and circuit T to "1" alternately in bit units.
and "0", that is, a call rejection signal indicating that the terminal device is normal but cannot accept incoming calls temporarily (this state is the "control not ready state"). This constitutes an incoming call rejection signal output means.

In addition, to set the circuit T to "1" and "0" alternately in bit units, the system control unit 8 sends "01010101".
This is done by writing the byte data of J (55H) or l-10101010J (AAH) to the communication controller 55 of the communication control unit 5, and the communication controller 55 converts this parallel data into serial data and sends it to the circuit T. Output to.

Further, when the CNR status command switch 9 is turned off after being turned on, the system control unit 8 sets the circuit T to “1” and the circuit C to “OFF” to the communication control unit 5. A CCU ready state command ratio is input to make the CCU ready state and ready state to accept incoming calls.

With this configuration, when performing special local work, the operator turns on the CNR status command switch 9.

That is, for example, when copying all of one floppy disk for a bank amplifier, the system control unit 8
Under the control of O8, a floppy disk copy program from the floppy disk in the external storage section 4 is loaded into the non-resident program area of the RAM 82 and put into execution.

This program instructs the operator to set the floppy disk FDD 40 to be copied and the floppy disk FDD 41 to be copied. Therefore, the floppy disk storing various programs must be removed from the FDD 40.

If document information is received in this state, the received document information cannot be recorded.

Furthermore, when performing calculation work in the non-resident program area of the RAM 82 of the system control unit 8, the program may run out of control and damage the O8 before the program is completed, and if this overlaps with reception, the received document information may be lost. I end up.

Therefore, when performing such special local work, the CNR status command switch 9 is turned on.

As a result, the system control unit 8 transmits C to the communication control unit 5.
The CU CNR status command is output, and the communication control unit 5 outputs an incoming call rejection signal (Circuit C is OFF J, ・Circuit T
Since [IJ, rOJ) are outputted alternately in bit units, the line connection unit 7 transmits a call progress signal "call rejection" to the calling party.

Incidentally, the flow of the processing program of the system control unit 8 in this case is shown in FIG.

As a result, the calling party recognizes that the other party's terminal device is in a busy state and does not send document information.

Therefore, the above-mentioned special local business can be performed using the document creation communication terminal device.

Then, when special local operations are completed, CNR
By turning off the state command switch 9, the system control section 8 outputs a CCU ready state command to the communication control section 5, so that the document creation communication terminal device becomes ready to accept new calls. .

Note that instead of the CNR status command switch 9 as in this embodiment, a dedicated program for outputting the CCU CNR status command and CCU ready status command from the system control unit 8 is stored in the floppy disk of the external storage unit 4. It is also possible to load this dedicated program into the non-resident program area of the RAM 82 of the system control unit 8 and execute it when performing a special local business.

Furthermore, as shown in FIG. 10, a program for sending the CCU CNR status command and CCU ready status command may be incorporated into a special local business program.

In these cases, the incoming call rejection signal output means is configured by a dedicated program or a special local business program.

Next, although this is not a special local business, incoming calls cannot be accepted even while the communication control unit 5 is receiving document information and outputting the received document information to the system control unit 8.

In this embodiment, as shown in FIG. 11, in the document receive program constituting the CCU control program stored in the communication control unit 5, there is a program to set the control not ready (CNR) state. In other words, it incorporates a program that outputs a call rejection signal to the communication line.

That is, the document receive program constitutes the incoming call rejection output means and the incoming call rejection signal output command means.

By doing this, while the received document information is being output from the communication control section 5 to the system control section 8, a call progress signal "call rejection" is transmitted to the calling terminal device.

As described above, according to the present invention, special local business can be performed using the document creation communication terminal device.
