Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a private telephone exchange device that displays a display corresponding to a meet-me response in a private telephone exchange.

In general, a private telephone exchange for an incoming call is performed by having an attendant temporarily put the incoming call on hold, then calling the called telephone's extension, and connecting the incoming call to that telephone. If the called telephone does not respond, the hold is canceled (line restoration) and the attendant notifies the incoming call that the called party is absent. In this manner, in telephone exchange control by the attendant, the holding of incoming calls is effectively utilized. By the way, in addition to the telephone switching operation by the addendum that involves holding incoming calls, recent telephone switching systems also park incoming calls and call the parked incoming calls by performing a specific dialing operation. There is a meet-me response function where the side responds. This meet-me response is used when the called party is absent or the called telephone is busy, the incoming call is parked by a specified dialing operation on the attendant, and then the called party is called by mass paging. This function allows the called party to answer the parked incoming call by dialing a specified number using an arbitrary telephone set.
Therefore, after the incoming call is parked, the called party can directly answer the incoming call without going through an attendant, which is an excellent feature.

However, the display installed on the attendant's desk in the conventional private telephone exchange equipped with the meet-me response function does not display any information regarding the incoming call after the incoming call is parked and the subsequent paging operation is performed. . Therefore, the attendant cannot know whether or not the parked incoming call has been answered. In addition, since the number of lines provided in the above park is usually one, or at most two or three, it is difficult to take appropriate measures when it becomes necessary to perform meet-me response processing for the next incoming call. There was a problem. In addition, when the park line is blocked, an overflow tone is generally emitted to the attendant, but this tone has to be identified before replacement processing is performed, which is inefficient.

The present invention has been made in consideration of these circumstances, and its purpose is to improve the work efficiency of attendants and the operating efficiency of switching equipment by accurately grasping the park status of incoming calls. An object of the present invention is to provide a simple and highly practical private branch telephone exchange.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic configuration diagram of an embodiment device. In the figure, reference numeral 1 denotes a private branch exchange (PBX), which is connected to outside lines via a plurality of central office lines 2a, 2b to 2n, and is equipped with a plurality of private telephones 3a, 3b to 3m. An attendant console 5 connected to the PBX 1 via a data transmission line 4 is operated by an attendant (not shown) and handles processes such as answering incoming calls, connecting a line to a predetermined telephone, and parking. Enter control input. This attendant table 5
A display, ie, a busy lamp field 6, is provided to display the line connection status and park status of the PBX 1, which are input from the PBX 1 via the data transmission line 4.

However, the attendant
n or telephones 3a, 3b to 3m, and responds to an incoming call from the designated telephones 3a, 3b to 3m.
3m, and if it becomes necessary to park the incoming call due to a busy call or other reasons, the specified operation of the attendant console 5, that is, the special number Perform dial operations. This operation information is input to the PBX 1 via the data transmission line 4, and a search is made to see if there is an incoming call that has been parked. At this time, if there is already a parked incoming call and there is no vacant space in the park area, the attendant responds to the incoming call to that effect. As a result, necessary measures such as a promise to return the call will be taken. On the other hand, if the park area is vacant, the incoming call is parked as is. At this time, the PBX 1 responds to the park of the incoming call and sends park data to the attendant console 5, thereby indicating the park.
The lighting display of BLF6 is performed corresponding to the above park. This allows the attendant to confirm the park of the incoming call, and then paging the called party using paging operations and paging information about the response to the park, such as "Mr. . This completes the parking process of the incoming call by the attendant and the necessary actions associated with it, and the attendant prepares for the next incoming call. Further, the park information displayed on the BLF 6 is continuously displayed until the called party responds to the parked incoming call by a specified dial operation.

By the way, the called party who knows that the incoming call has been parked due to paging etc. uses the telephone set 3a, 3b to 3n whose extension is open and performs a specified dialing operation for a meet-me response, that is, dials a special number. do. This establishes a line connection between the telephone set and the parked incoming call, and a meet-me response is performed. Incidentally, even if the above-mentioned special number is dialed in a state where an incoming call is not parked, no line connection will be made because the park area is in an open state. Then, when the above meet-me response is established, PBX1
Meet-me response establishment information is sent to the controller, and as a result, the lighting drive of the park display by the BLF 6 is controlled to stop, that is, the light is turned off. At the same time, the parked incoming call is returned to the line and a telephone conversation is made through the telephone set that the called party answered. Therefore, the attendant can know the completion of the meet-me response for the parked incoming call by turning off the BLF 6, and therefore can take appropriate measures even if meet-me response processing is required for the next incoming call. can be applied. That is, by understanding the park status, it is possible to take appropriate measures, such as performing a new parking operation or responding to an incoming call indicating that the vehicle is parked and asking for another call.

By the way, I responded to this kind of park processing.
If the PBX 1 is an electronic exchange, the lighting display of the BLF 6 may be controlled by extracting data according to the execution of its control program, but generally it is controlled by the hardware as shown in Figure 4. realizable.

That is, the activation of the park area of the exchange main body 1 is detected by the reservation detector 11, and the status determination circuit 12 consisting of, for example, a flip-flop is set. In response to the set output of the determination circuit 12, the drive circuit 1
3 is activated and drives the display 14 (BLF6) to light up, thereby displaying whether the incoming call is parked. Further, in conjunction with this park detection, the response detector 15 is energized and set to detection mode. The response detector 15 is configured to detect a dial signal from the telephone of the called party to the park area where the incoming call is parked, and the state determination circuit 12 is reset by this detection. As a result, the lighting display on the display 14 stops (turns off) in response to the reset of the determination circuit 12, so that a display corresponding to the incoming call park and the meet-me response to this park can be displayed. . In addition, the drive circuit 13 from the detectors 11 and 15 is connected to the exchanger main body 1.
However, it is also possible to incorporate these into the attendant stand 5. It goes without saying that the detection results of the detectors 11 and 15 may be transmitted to the attendant stand 5.

As explained above, according to the present device, it is possible to appropriately display a meet-me response by using a display element that indicates the park of an incoming call, without using a special display device for confirming the meet-me response. Therefore, the attendant can always accurately grasp the park status of the incoming call, and can therefore respond appropriately without performing unnecessary dialing operations. In addition, if the incoming call remains parked for a long time, a meet-me response can be prompted by paging again, thereby improving the effective operation of the exchange and the processing efficiency of the attendant. Furthermore, the functions of this device can be easily incorporated into conventional exchanges that have already been installed, so it has great effects such as high practicality.

Note that the present invention is not limited to the above embodiments. For example, the number of lines on which incoming calls are parked may be determined depending on the scale of the exchange. When multiple park areas are set, the device must be configured to display a park corresponding to each park area, for example, by driving number-corresponding display elements or driving a number display. Bye. Further, the exchanger can be of various types, such as an electronic type or a crossbar type, and the detection mechanism can be configured accordingly. In short, the present invention can be implemented with various modifications without departing from the gist thereof.
