The information specific to the line 2 is registered by the operator. The line-specific information includes “telephone number (facsimile number)”, “source name”, “dial”, “line type”, and “purpose”.

In the "telephone number (facsimile number)", a telephone number assigned to a line is registered, and is used for a TSI signal and a TTI (caller display). "Sender name"
Is registered as a transmission source, and is used for TTI. “Dial” is a tone (“DTM”) as a dialing method used when making a call.
F ") or pulse (" 10PPS "or" 20PPS ")
S ”) is registered.

As the "line type", any one of "external line", "extension (dedicated)", and "extension (external line calling number)" is registered. If the "extension" is connected to the public line network, the "extension (dedicated)" is connected to the extension exchange, and if the extension exchange cannot connect to the public line, the "extension (external calling number)" is assigned to the extension exchange. It means that it is connected and can be connected to a public line network by dialing an outside line calling number. In the present embodiment, the line L1 is an outside line and the line L2 is an extension that can be connected to a public line network. However, the present invention is not limited to this and can be appropriately selected.

"Use" is "transmission only", "reception only",
One of "shared" is registered. "Send only" uses the line only for transmission and does not respond when there is an incoming call. "Receive only" uses the line only for reception and does not use it for transmission. It means that it is used for both.

FIG. 5 shows the destination table T2. In the destination table T2, the destination telephone number and the name of the destination are registered by the operator for each abbreviated number and one-touch dial. The destination phone number can be registered as either an extension destination phone number or an external line destination phone number. If there is an “!” At the end (last digit) of the number, Indicates that it is the other party's phone number, and ends with "!"
If there is no telephone number, it indicates that the telephone number is for the extension.

FIG. 6 shows a line status table T3. The line status table T3 indicates which of the modem 2, the telephone TEL1, and the telephone TEL2 is using the lines L1 and L2. “1” indicates that it is in use, and “0” indicates that it is empty, and is sequentially changed by the CPU 12 according to the situation.
For lines L1 and L2, modem 2, telephone TEL1,
If all of TEL2 are empty, the line is available. When the lines L1 and L2 of the modem and the telephones TEL and TEL2 are free, the modem and the telephones TEL1 and TEL2 can be used.

FIG. 7 shows a line selection table T4. The line selection table T4 is used in a line selection process described later, and is used to select a line to be used when calling from the facsimile machine F. One of “calling enabled”, “call waiting”, and “calling disabled” is set by the CPU 12 according to the situation.

The processing for automatic facsimile transmission will be described with reference to FIGS. FIG. 8 is a flowchart showing a process in the case where a call is made from the facsimile apparatus F and facsimile transmission is automatically performed.

First, a document to be transmitted by an operator is set on a document table (not shown) (S101), and the destination telephone number is entered by the ten keys 41, speed dial keys 42, and one-touch dial keys 43 of the operation unit 4. Is entered. When the ten key input and the abbreviated number input are performed, the start key 44 is subsequently pressed (S102).
When inputting the telephone number of the transmission destination from the numeric keypad 41, either the telephone number for the public line network (external line) or the telephone number for the internal exchange (extension) can be input. , Add "!" To the end.

A line selection process is executed to select a line to be used (S103). The line selection processing will be described with reference to FIG. First, destination information is acquired (S201). In S102, when the destination is input by the abbreviated number and the one-touch dial, the destination telephone number and the destination name are acquired from the destination table T2.

Next, the line L is obtained from the line attribute table T1.
1. The line attribute information of L2 is acquired (S202). First, it is determined whether the "use" of the line L1 is "reception only" (S203). In the case of "reception only", since transmission cannot be made from the line L1, "outgoing transmission" is set in "selection result" of the line L1 in the line selection table T4 (S204), and the process proceeds to S209.

If it is not "reception only", it is determined whether or not the "line type" of the line L1 matches the type of the telephone number of the destination input in S102 or obtained in S201 (S205). This is to prevent the transmission of the extension telephone number to the public line network and the transmission of the external telephone number to the extension exchange. The extension telephone number and the outside line telephone number can be distinguished by whether "!" Is added at the end. If the "line type" does not match, it is not possible to make a call from the line L1, so that "outgoing call" is set in "selection result" of the line L1 in the line selection table T4 (S204), and the flow proceeds to S209.

If the "line type" matches, the line L
It is determined whether 1 is usable with reference to the line status table T3 (S206). If the line L1 is already in use by modem communication or telephone TEL1 or TEL2 and cannot be used, if the communication or the call is terminated, the line may become available.
"Call waiting" is set in the "selection result" of the line L1 in the line selection table T4 (S207). If the line L1 is empty and usable in all of the modem and the telephones TEL1 and TEL2, the line L in the line selection table T4 is used.
In the "selection result" of No. 1, "calling possible" is set (S20).
8).

S203 to S20 for the line L1
8 is also performed on the line L2 (S209).
To S214). When the line selection processing of FIG. 9 is completed,
The “selection result” of the line selection table T4 includes the line L1,
For L2, any one of "outgoing call possible", "outgoing call waiting", and "outgoing call impossible" is set.

Here, the description returns to FIG. The line to be used is selected with reference to the "selection result" of the line selection table T4. It is determined whether or not the line L1 is "callable" (S104). If the line L1 is "callable", the line L1 is selected (S105). On the other hand, if the line L1 is not "callable", it is determined whether the line L2 is "callable" (S106). Line L2 is "callable"
If so, the line L2 is selected (S107).

If the line L2 is not "callable",
It is determined whether at least one of the lines L1 and L2 is "waiting for transmission" (S108). If at least one of the lines L1 and L2 is not "call waiting", that is, if both are "outgoing call impossible", no call can be made from any line, so the facsimile automatic transmission process ends.

If at least one of the lines L1 and L2 is "call waiting", redialing after a predetermined time may result in "call possible" (S109). Redialing is performed a predetermined number of times at predetermined time intervals (for example, 3 times every 5 minutes).
Call). When redialing is performed, the process returns to S103 after a predetermined time. If a line cannot be selected despite redialing a predetermined number of times, the facsimile automatic transmission process ends.

If the line used for calling can be selected, the line state table T3 is updated (S110). Since the modem 2 is used for facsimile transmission, the use state of the modem of the selected line is changed to "1 (in use)". Next, the fourth line RL4 is controlled to connect the selected line to the modem 2, and the first and second relays RL1, RL2 are controlled to disconnect the telephone connected to the selected line from the line ( S111).

Further, the fifth relay RL5 is closed, the DC circuit of the selected line is closed, and a dial signal is transmitted (S112). The dial signal is stored in the line attribute table T.
The DTMF or dial pulse is transmitted by controlling the auto dialer 2 based on the "dial" of No. 1. To send a telephone number for an external line with "!" At the end of the other party's telephone number to a line whose "line type" is "extension (external line calling number)", Prior to the transmission of (1), an outside line calling number (for example, “0”) is transmitted.

If there is a response from the destination facsimile machine within a predetermined time after the call is made (S113, S114),
Facsimile communication is performed (S115), but if there is no response, the process proceeds to S116. After the end of facsimile communication, the fifth relay RL5 is returned to open the DC circuit, and the first, second,
Return the fourth relays RL1, RL2, RL4 to the standby state (S
116). Then, the line use state of the line state table T4 is returned to "0 (empty)" (S117), and the facsimile automatic transmission process ends.

FIG. 10 is a flowchart showing a process when a call is made from the telephone TEL1. Telephone TEL1
Since the direct current is supplied from the line L1 or the pseudo bell generating unit 17, the telephone T
Off-hook of EL1 can be detected. Telephone T
When the off-hook of EL1 is detected (S301), it is checked whether or not the line L1 is available by referring to the line state table T3 (S302). If the line L1 is in use, the telephone TEL1 cannot be used. Therefore, the fact is displayed on the display unit 8 (S303), and the calling process is terminated.

If the line L1 is usable, the use state of the TEL1 of the line L1 in the line state table T3 is changed to "1" (S304). After that, the other party's telephone number is sent out by the dialing operation of the operator, and after the other party answers, a call can be made (S305). When the off-hook detection circuit OH1 detects the on-hook of the telephone TEL1 (S306),
The use state of TEL1 of the line L1 in the line state table T3 is returned to "0" (S307).

FIG. 11 is a flowchart showing a process when a call is made from the telephone TEL2. Telephone TEL2
Is operated by the operator operating the third relay RL3.
The connection to the line L1 or L2 can be selected. Since the telephone TEL2 is supplied with a direct current from the lines L1, L2 or the pseudo-bell generator 17, the off-hook detector OH2 can detect the off-hook of the telephone TEL2.

When the off-hook of the telephone TEL2 is detected (S401), it is determined which contact is closed by the third relay RL3 (S402). When the contact e is closed, the line status table T3 is determined. , It is checked whether the line L1 is available (S403). Line L
If the telephone 1 is in use, the telephone TEL2 cannot be used, and the fact is displayed on the display unit 8 (S40).

If the line L1 is usable, the use state of the TEL1 of the line L1 in the line state table T3 is changed to "1" (S405). After that, the telephone number of the other party is transmitted by the dialing operation of the operator, and after the other party answers, a call can be made (S406). When the off-hook detection circuit OH2 detects the on-hook of the telephone TEL2 (S407),
The use state of the TEL2 of the line L1 in the line state table T3 is returned to "0" (S408), and the calling process is terminated.

If the contact f is closed in S402, it is checked whether or not the line L2 is usable by referring to the line state table T3 (S409). If the line L2 is in use, the telephone TEL2 cannot be used. Therefore, the fact is displayed on the display unit 8 (S404), and the calling process ends.

If the line L2 is available, the use state of the TEL2 of the line L2 in the line state table T3 is changed to "1" (S410). Thereafter, the telephone number of the other party is transmitted by the dialing operation of the operator, and after the other party answers, a call can be made (S411). When the off-hook detection circuit OH2 detects the on-hook of the telephone TEL2 (S412),
The use state of the TEL2 of the line L2 in the line state table T3 is returned to "0" (S413), and the calling process ends.

When making a call from the telephone TEL1 or TEL2, it is necessary for the operator to judge the line type. In other words, when calling from the telephone TEL2 to the public line network with the contact f of the third relay closed, it is necessary to dial the outside line calling number before the telephone number of the other party.

Next, the processing when there is an incoming call on the line L1 will be described. In the line L1, a facsimile automatic reception (FAX type) mode and a telephone /
The operator can select one of the FAX switching (TEL / FAX) modes. It is determined whether or not the CI detector 15 has detected the CI (S501). When CI is detected,
It is determined whether or not the modem 2 is free with reference to the line state table T3 (S502). If the modem 2 is in use, the incoming call cannot be answered and the incoming call process ends (S503).

If the modem 2 is usable, the use state of the modem on the line L1 in the line state table T3 is changed to "1" (S504). Close the fifth relay RL5 and set the line L
