【Example】

 FIG. 1 is a block diagram showing an embodiment of the present invention. As shown in the figure, the private branch exchange 1 has a main control unit 2, an office line interface 3, an extension line interface 4, a fax machine automatic switching means 5, an idle line confirmation means 6 and a switching means 7. This private branch exchange 1 has a representative function and, as shown in the configuration diagram of FIG. 2, is connected to the central office switching network 9 through a telephone line 8a and a fax machine line 8b, and has a plurality of extension lines 10a-10n. It is connected to the extension telephones 11a to 11i and the extension facsimile machine 12. The telephone line 8a and the facsimile line 8b are previously registered in the central office switching network 9 as transfer destinations.

The idle line confirmation means 6 confirms the usage status of the telephone line 8a and the facsimile line 8b. The switching means 7 switches the fax machine automatic switching means 5 to a vacant line upon confirmation by the vacant line confirmation means 6. The automatic facsimile switching means 5 detects a non-ringing incoming call when an incoming call is received from the external telephone 13a, 13b or the external facsimile 14 to the telephone line 8a or the facsimile line 8b. When the other party is a telephone, the extension telephones 11a to 11i are connected.

The operation of the private branch exchange 1 having the above-described structure when an incoming call is received from the outside line telephones 13a and 13b or the outside line facsimile 14 will be described with reference to the flowchart of FIG.

The idle line confirmation means 6 always confirms the use states of the telephone line 8a and the facsimile line 8b, and when both the facsimile line 8b and the telephone line 8a are idle (step S1), the facsimile line 8b is idle. However, for example, when the telephone line 8a is in use due to an incoming call from the external telephone 13a to the internal telephone 11a (step S2), the switching means 7 is connected so that the automatic facsimile switching means 5 is connected to the facsimile line 8b. The automatic ringing function of the automatic facsimile switching means 5 is switched to the facsimile line 8b (step S3). In this way, when the facsimile line 8b is empty, the silent ringing function is applied to the facsimile line 8b, so that the external line telephone 13b receives an incoming call from the external telephone 11i or the external line facsimile 14 to the internal line facsimile 12 via the facsimile line 8. can do.

When a telephone call is being made from the extension telephone 13a to the extension telephone 11a using the facsimile line 8b and the telephone line 8a is idle (step S4), the facsimile automatic switching means 5 is connected to the telephone line 8a. Then, the switching means 7 is switched so as to activate the non-ringing incoming call function of the facsimile automatic switching means 5 on the telephone line 8a (step S5). In this way, when the facsimile line 8b is in use, the silent ringing function is activated on the telephone line 8a. When an incoming call is received from the outside line facsimile 14, the representative ringing function automatically switches to the telephone line 8a and the silent ringing call is received. The function enables the extension facsimile 12 to receive a call.

Next, the operation when a call is made from the extension telephones 11a to 11i or the extension facsimile 12 to the outside line will be described with reference to the flowchart of FIG.

For example, when the extension telephone 11a makes a call to the outside telephone 13a to call the facsimile line 8b and captures the facsimile line 8b (step S11), the function key of the extension telephone 11a, for example, "* 1" Is operated to set the transfer function in the central office switching network 9 (step S12). The idle line confirmation means 6 that has detected the capture of the facsimile line 8b switches the switching means 7 so that the automatic facsimile switching means 5 is connected to the telephone line 8a, and the silent ringing function of the automatic facsimile switching means 5 is set to the telephone line 8a. To work (step S13). When a call is received from the external line facsimile 14 to the facsimile line 8b during a call from the extension line telephone 11a to the external line telephone 13a via the facsimile line 8b (step S14), the incoming call is made by the transfer function of the central office switching network 9. The data is transferred to the line 8a and is connected to the extension facsimile 12 by the silent incoming call function of the facsimile automatic switching means 5 (step S15).

When the call from the extension telephone 11a to the outside telephone 13a ends (step S16), the transfer button is released by operating the function button of the extension telephone 11a (step S17).

When the extension facsimile 12 makes a call to the telephone line 8a, the same operation and processing as described above are performed.

In this way, incoming calls from the outside line facsimile 14 can be processed even while the facsimile line 8b is in use, and incoming calls from the outside line telephones 13a and 13b can be processed even when the telephone line 8a is in use.

Even when the telephone line 8a and the facsimile line 8b are used in common for a telephone and a facsimile respectively as described above, a key system or a key telephone is provided between the central office switching network 9 and the private branch exchange 1. If there is a device, it is not possible to select the extension telephone 11a from the extension telephone 13a to receive the call directly, but it is necessary to intervene the telephone of the key system or the key telephone device. Even in this case, if the special number is input so that the incoming call can be made directly between the outside line and the extension line, the processing of the above-described embodiment can be performed.

[0021]

[Effect of the device]

 As described above, the present invention confirms the usage status of the facsimile line and the telephone line, and even if the facsimile line is in use, the facsimile automatic switching means is activated to another available telephone line to automatically send the facsimile automatically. By effectively using the switching function, it is possible to effectively utilize the line and reduce the failure rate of incoming faxes.

Further, when a call is made to the facsimile line or telephone line from an extension facsimile or an extension telephone, the transfer function is set from the calling line to the office line so that the facsimile line is in use. However, since the facsimile call is processed and the telephone call is processed even when the telephone line is in use, the facsimile line and the telephone line can be effectively used.

The transfer function can be set accurately and quickly by setting the transfer function for the central office line by one-touch with the function button of the extension facsimile or the extension telephone.
