[Traditional technique (nei)]

FIG. 4 is a diagram showing an example of a conventional automatic private branch exchange.

In FIG. 4, a subscriber of a public telecommunications network (not shown) dials extension 2 in order to receive a dial-in call to extension 2 of the automatic local exchange 1. When the telephone number n2 is dialed, the public communication network acquires a vacant dial-in office line 3 connected to the automatic private branch exchange 1 and sends out an activation signal.

In the automatic horizontal switchboard 1, the central office trunk (COT)
) 4 receives the activation signal transmitted via the dial-in office line 3, the dial-in connection section 51 in the central control unit 5 is activated.

The dial-in connection unit 51 controls the communication network (NW) 6, connects the office line trunk 4 that has received the activation signal to the telephone number receiving device (PI3R) 7, and then connects the office line trunk 4 to the dial-in station. A start-up completion signal is sent back to the public communication network via line 3.

The public communication network that has received the activation completion signal converts the lower several digits (for example, 1 to 4 digits) of the telephone number n2 of extension 2 to extension number na.
g, and is sent to the dial-in office line 3.

In the automatic private branch exchange l, the telephone number reception bag w7 is transmitted via the dial-in office line 3 to the extension number n1.
is received and transmitted to the dial-in connection section 51.

The dial-in connection unit 51 selectively acquires the extension 2 based on the extension number nag, and causes the subscriber circuit (SLC) 9 to send a calling signal to the extension 2. When the extension 2 answers, the telephone network 6 is controlled 2 to connect the office line trunk 4 and the subscriber circuit 9, and the extension 2 is made to answer the caller of the public communication network.

Note that when the dial-in connection unit 51 selects extension 2, the number is 1.9! 2 is busy, or if the extension 2 that received the calling signal does not respond within a predetermined time due to being absent or the like, the dial-in connection section 51 activates the relay board transfer section 52.

The attendant transfer unit 52 stops the call processing for the extension 2, controls the communication path network 6, connects the office line trunk 4 and the attendant control circuit (ATTC) 10, and transfers the call to the attendant (ATT) 1.
] to display an incoming call.

The operator of relay console 11 who notices the incoming call display responds to the caller by performing a predetermined response operation.

At this time, the relay transfer unit 52 activates the number display unit 54 in the same way as when receiving an existing central office line call, and the number display unit 54 reads the trunk number from the area 81 in the main storage device 3 stored in advance corresponding to the trunk. ncl is extracted and transferred to the area 83 corresponding to the number display section of the relay stand 11. The dial-in trunk number ncI is displayed on the display unit 14 of the relay console 11.

On the other hand, when a subscriber of the public communications network dials the representative number np assigned to the automatic private branch exchange 1, the public communications network dials the vacant trunk office line 12 connected to the automatic private branch exchange PBX.
and sends out a calling signal.

In automatic horizontal switchboards, the central office trunk (COT)
) 13 receives the call signal transmitted via the relay station NlAl2, the relay stand connection unit 5 in the central control device 5
3 is activated.

The relay console connection unit 53 controls the communication path network 6, connects the office line trunk 13 that has received the activation signal to the relay console control circuit 10, and then causes the relay console 11 to display an incoming call.

When the operator of the relay console 11 who notices the incoming call display performs a predetermined response operation, the relay console connection section 53 activates the number display section 54 . Number display section 54, relay station line 1 in main storage device B
After transferring the line number nc2 assigned to the relay station line 12 stored in the relay station line 12 corresponding area 82 to the number display area corresponding area 83 of the relay station 11, The line number nct stored in the area 83 is displayed on the number display section 14 of. Also, the office line trunk 13 is placed in a response state to the relay station office line 12.

The operator recognizes the number of the relay station line 12 that responded from the line number n3□ displayed on the number display section 14, and responds to the caller on the public communication network.

[Problem to be Solved by the Invention 3] As is clear from the above explanation, in conventional automatic private branch exchanges, the operator of the attendant 11 is responsible for determining whether a dial-in call transferred to the attendant 11 is an incoming call at the attendant. If the caller responds in the same way as an incoming call from the attendant, it will be an inappropriate response to the caller who is expecting a response from extension 2, and the service quality for the caller will be compromised. Become.

[Means for solving problems] FIG. 1 is a diagram showing the principle of the present invention.

In FIG. 1, when #, who handles the relay console 11, responds to a dial-in call transferred to the relay console 11 in an automatic private branch exchange 1 equipped with a dial-in function, the called extension 2 A number display means 100 is provided as means for displaying an extension number.

[Function] That is, according to the present invention, when responding to a dial-in call transferred to the relay console 11, the operator can identify the extension number of the called extension 2, After recognizing that an incoming call has been transferred, it is possible to respond to the caller, allowing appropriate response to the caller and improving serviceability.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 2 is a diagram showing an automatic private branch exchange according to an embodiment of the present invention. Note that the same reference numerals refer to the same objects throughout the plan.

In FIG. 2, the relay board transfer section 521 is the number display section 5.
22 is activated as the number display means 100 and has an iT function.

In Figure 2, when a subscriber of the public telecommunications network dials the telephone number n2 assigned to extension 2 in order to receive a dial-in call to extension 2 of automatic private branch exchange l, the public telecommunications network A vacant dial-in office line 3 connected to exchange I is captured and a activation signal is sent, and when an activation completion signal is returned from automatic private branch exchange l, the called extension number n
Transfer ap.

In the automatic private branch exchange 1, when the central office line trunk 4 receives an activation signal arriving from the dial-in central office line 3 (i),
The dial-in connection unit 51 in the central control unit W5 is activated, connects the office line trunk 4 to the telephone number receiving device 7, returns a activation completion signal to the public communication network, and receives the extension number na2 transferred from the public communication network. When received, extension 2 is selectively captured and a calling signal is sent from subscriber circuit 9 to extension A.

Therefore, in the present invention, the dial-in connection section 51 stores the extension number n12 in the area 84 corresponding to the dial-in station line 3 in the main storage device 8.

When dial-in connection section 51 selects extension 2, extension 2
is busy or extension 2 receives the ringing signal.
If the dial-in connection unit 51 does not respond within a predetermined time due to reasons such as absence, the dial-in connection unit 51 activates the relay board transfer unit 521.

The attendant transfer unit 521 stops the call processing for the extension 2, controls the communication path network 6, connects the office line trunk 4 and the attendant control circuit 10, and displays the incoming call to the attendant 11. Ru.

When the operator of the relay console 11 who is concerned about the incoming call display performs a predetermined response operation, the relay console transfer unit 521 changes the number display unit 522
Start. After the number display section 522 transfers the extension number nag stored in the dial-in station line 3 corresponding area 84 in the main storage device 8 to the number display section corresponding area 83 of the relay console 11, the relay console control circuit 10 The extension number n stored in the area 83 is displayed on the number display section 14 of the relay console 11 via
,! Display. Based on the extension number nov displayed on the number display section 14, the operator recognizes that the dial-in call that arrived at internal vA2 has been transferred to the attendant console 11, and transfers the call to busy extension 2.
The caller will respond appropriately to the caller of the public communication network, such as interrupting connection to the network or arranging an extension to call instead.

On the other hand, an incoming call to the relay station line 12 from the public communication network is received at the relay station 11 in a process similar to that shown in FIG. 3, and when answered, extension numbers n, ! The line number ncl of the relay station line 12 that can be identified as ``ncl'' is displayed on the number display section 14.

FIG. 3 is a dial-in control flow diagram according to the present invention. In FIGS. 2 and 3, when an incoming call on the central office line is detected by receiving an activation signal, the type (class) of the incoming trunk is determined from the trunk class table (Te1.S) (step Sl).

If the central control unit 5 determines that the trunk type is a dial-in trunk 4, the trunk 4 is connected to the telephone number reception bag W7 via the communication path network 6 (step S7). Next, it sends a start-up completion signal to the public communication network (step S3) and receives extension numbers n, , z from the other party's exchange (step S3).
(Step S4).

The received extension numbers n, l+ are converted to the internal number nl within this exchange.
(Step S5). There are two ways to carry out this conversion: one treats the number 7 received from the public communication network as the same as the extension number, and the other treats it as an internal number.

Next, if the extension subscriber corresponding to extension number n1 is busy (step S6), and if the extension subscriber is idle and calling (
In step S7), if there is no response despite the calling for a certain period of time (step S8), the line number ncl of the central office line corresponding to the incoming trunk is extracted from the trunk memory, etc., and the line number ncl is displayed on the relay stand. (Step S10).

Therefore, in the present invention, after waiting for a response from the relay console operator (step 511), the extension number 0.2 is displayed on the display section of the relay console (step 312), and the caller of the public communication network and the relay console operator are Enters the state of kissing in episode 1 of JL (Step 7, B513). If the extension subscriber responds within a predetermined time from extension subscriber calling 2 (step S7), the state shifts to a conversation state between the caller of the public J11 network and the extension subscriber (step 514).
).

The major difference from the conventional technology is that in the above process, the relay stand display in the case of a dial-in call is changed to the trunk number (or line number) display in the case of a general office line call, and
The feature is that it displays the subscriber number of the extension that received the call.

As is clear from the above description, according to the present embodiment, when a dial-in call that arrives at extension 2 is transferred to the attendant 11, the number display section 14 of the attendant 11 displays the number of the attendant office line 1.
Since the line number nc2 of 2 and the extension number 0.2 of the called extension 2, which can be identified, are displayed, the handler confirms that each time a dial-in call is transferred and that the called extension number is n, 2. It becomes possible to recognize and respond to an incoming call by distinguishing it from an incoming call from a relay stand.

It should be noted that FIGS. 2 and 3 are only one embodiment of the present invention, and for example, if extension 2 is incorrect. An incoming dial-in call that is answered at t5 is not limited to being transferred to the relay console 11, and may also be transferred to a distributed relay console; however, the effects of the present invention can be achieved even in such a case. does not change. Note that when transferring to a distributed relay stand, it may be considered to display the extension number nez on the station line number display panel. In addition, when a dial-in call arrives at the attendant console, a dedicated button for dial-in response (different from the answer button for incoming calls at the attendant console) should be provided, or the extension number should be displayed on a display that can be recognized as dial-in. However, the effect of the present invention remains unchanged. It goes without saying that the configuration of the automatic private branch exchange 1 is not limited to that shown in the drawings.

Furthermore, for incoming calls from the central office line, write the extension number corresponding to the central office line↑
The effect of the present invention does not change even if it is applied to a direct-in-line method in which a call is received on a specific extension that has been set to a.

〔Effect of the invention〕

Therefore, according to the present invention, when the automatic private branch exchange responds to an incoming dial-in call transferred to the attendant, the operator can recognize the number of the called extension, and As soon as the caller recognizes that an incoming dial-in call has been transferred due to non-answer, the caller can respond, appropriate response can be made, and serviceability is improved.
