DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data communication apparatus such as a facsimile apparatus capable of recognizing a telephone number of a calling terminal prior to a line connection.

[0002]

2. Description of the Related Art Conventionally, prior to a line connection, a facsimile apparatus capable of recognizing a telephone number of a calling terminal has been proposed.
It is known that a telephone number to which an incoming call is permitted is registered, an incoming call from a registered telephone number is permitted, and an incoming call from an unregistered telephone number is prohibited.

[0003]

By the way, in the above-mentioned conventional facsimile apparatus, when a plurality of lines are accommodated, the permission of the incoming call is controlled by the registered telephone number regardless of the availability of the lines.

FIG. 1 is a block diagram showing the configuration of a facsimile apparatus according to one embodiment of the present invention.

An NCU (network control unit) 2 connects to a terminal of the line in order to use the telephone network for data communication and the like.
It controls connection of the telephone exchange network, switches to a data communication path, and holds a loop. The NCU 2 connects the telephone line 2a to the telephone when the signal level (signal line 20a) from the control circuit 20 is "0", and connects the telephone line 2a when the signal level is "1".
Is connected to the facsimile machine side. In a normal state, the telephone line 2a is connected to the telephone 4 side.

The hybrid circuit 6 separates the transmission system signal and the reception system signal, sends the transmission signal from the addition circuit 12 to the telephone line 2a via the NCU 2, and receives the signal from the other party via the NCU 2. , To the modem 8 via the signal line 6a.

The modulator / demodulator 8 is based on ITU-T Recommendation V. 8,
V. 21, V.I. 27ter, V.I. 29, V.I. 17, V.I.
The modulation and demodulation are performed based on the signal line 34, and each transmission mode is specified by the signal line 20c. The modem 8 receives the signal output on the signal line 20b, outputs the modulated data on the signal line 8a, receives the received signal output on the signal line 6a, and outputs the demodulated data on the signal line 8b. I do.

The ANSam transmission circuit 10 is a circuit for transmitting an ANSam signal. When a signal of signal level "1" is output to the signal line 20d, the ANSam transmission circuit 10 transmits the ANSam signal to the signal line 10a and outputs the ANSam signal to the signal line 20d. When the signal of the signal level “0” is being output, no signal is output to the signal line 10a.

The addition circuit 12 inputs the information of the signal line 8a and the information of the signal line 10a, and adds the result of the addition to the signal line 12a.
Output to The reading circuit 14 reads an image of a document and outputs the read data to a signal line 14a.

The recording circuit 16 is for sequentially recording information output to the signal line 20e line by line. The memory circuit 18 is used to store raw information of read data or encoded information, and also stores received information or decoded information.

The paging signal detection circuit 22 receives the information of the signal line 2b, and detects the paging signal when the paging signal is detected.
A signal of signal level "1" is output to signal line 2a, and when a calling signal is not detected, signal level "0" is output to signal line 22a.
The signal of is output.

The telephone number detecting circuit 24 receives the information on the signal line 2b and outputs to the signal line 24a the telephone number information on the calling side which is output between the call signals.

The above-mentioned NCU 2, telephone 4, hybrid circuit 6, modem 8, ANSam transmitting circuit 10, adder circuit 12, calling signal detecting circuit 22, telephone number detecting circuit 24
Are collectively referred to as a communication unit A.

The registration circuit 32 is a telephone number registration circuit of the AA group for registering a permitted telephone number having the highest priority via the signal line 32a when the calling priority is selected.

The registering circuit 34 registers a telephone number registered in the registering circuit 32 and, after the telephone number registered in the registering circuit 32, a permitted telephone number having a higher priority via the signal line 34a when the calling priority is selected. Is a telephone number registration circuit.

When the call priority is selected, the registration circuit 36 registers a permitted telephone number having a higher priority order via the signal line 36a following the telephone number registered in the registration circuit 34. Is a telephone number registration circuit.

The outgoing call priority / incoming call priority selecting circuit 38 is a circuit for selecting outgoing call priority or incoming call priority. When the outgoing call priority is selected, a signal of a signal level "1" is output to the signal line 38a and the incoming call is selected. When the priority is selected, a signal of signal level "0" is output to the signal line 38a.

Signals equivalent to 20b, 20c, 20d, 8b, 22a, and 24a are included.

The control circuit 20 controls the entire facsimile apparatus capable of recognizing the telephone number of the calling terminal while accommodating the lines by the three communication units A to C as described above. In particular, in the present embodiment, the control for changing the control at the time of incoming call according to the number of unused lines is performed.

Further, in the first embodiment of the present invention, the registration circuits 26, 28 and 30 can independently register the calling terminal to be permitted according to the number of unused lines. Further, the outgoing call priority / incoming call priority selection circuit 38 changes the condition of the calling terminal to be permitted according to the number of unused lines depending on the outgoing call priority and the incoming call priority, and the outgoing call priority is selected. In this case, it is determined that the number of unused lines is one less than when the incoming call priority is selected.

More specifically, when the incoming call priority is selected, if the number of unused lines is three, incoming calls of the telephone numbers of the groups A, B, and C are permitted, and the number of unused lines is two. In this case, the telephone numbers of the groups A and B are permitted to be received. When the number of unused lines is 1, the telephone number of the group A is permitted to be received. When the outgoing call priority is selected, the number of unused lines is set. If the number is 3, the telephone numbers of the groups A and B are permitted to be received. If the number of unused lines is 2, the telephone number of the group A is permitted. If the number of unused lines is 1, Do not allow incoming calls.
