[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an information control method in a telephone exchange device, and more specifically, to control information between a main control device in a PBX etc. and a telephone interface accommodating a button telephone. Regarding control method.

(Prior Art) FIG. 3 shows a block diagram of a telephone exchange device that accommodates a button telephone and this telephone. In the figure, a telephone exchange 1 includes line interfaces 2-1 to 2-n provided corresponding to the lines, a call path switch 3 for setting a call path, and an extension cable 7-1.
This telephone set (DP dial type, PB dial type) 6-1 to 6- is installed in a star shape via ~7-k.
A first telephone interface 5-1 is provided corresponding to each telephone interface 5-1, and button telephones are provided in a star shape via extensions 11-1 to 11-k (here, in order to provide a wide variety of services, , a telephone with display functions such as multiple lamps and displays, and multiple switch operation functions, etc.
(Defined as equipped with a control device such as MPU)
The main control device 4 is configured to include a second telephone interface 9-1 provided corresponding to each of the telephone exchange devices 10-1 to 10-k, and a main control device 4 that controls each part of the telephone exchange device 1. Here, a control line 8-1 connecting the first telephone interface 5-1 and the main control device 4, or a control line 8-n connecting the second telephone interface 9-1 and the main control device 4 The main control information that passes through is on-hook/off-hook signals, dial digit signals, and various tone output time timing signals. Furthermore, the control information specific to the button telephone set passing through the control line 8-n includes a blinking signal of a lamp provided on the button telephone set, information on pressing a switch, and display control information on a display. These various control signals are centrally controlled by the main control device 4, and the exchange operation is performed under the control of the main control device 4 based on these control signals.

Here, a method of processing control information specific to the key telephones 10-1 to 10-k performed between the main control device 4 and the second telephone interface 9-1 will be described with reference to FIG. FIG. 4 is a block diagram showing the main configurations of the main control device 4 and the second telephone interface 9-1. In the figure, 12 and 18 are respectively read-only memories (hereinafter referred to as ROM), 13 and 19 are random access memories (hereinafter referred to as RAM),

As the control information unique to the button telephones passing through -n, a control signal specifying the lamp number, switch number, etc. of each button telephone is used. Here, this information is referred to as individual physical control information. For example, the main control device 4 sends individual physical control information to the second telephone interface 9-1 such as "Turn on the lamp with lamp number n of the button telephone 10-1", and the second telephone interface 9
-1 to the main control device 4 is the “key telephone 1
Individual physical control information such as "The switch with switch number n of 0-k has been pressed down" is sent. In the main control device 4, in order to send such individual physical control information or to decode the individual physical control information sent from the second telephone interface 9-1, the individual physical control information is converted into an individual logic The information is converted into logical level information suitable for processing by the main controller 4. This corresponds to logical control information described later. Here, the individual logical information is information indicating the functional meanings of lamps, switches, etc. of individual key telephones. for example,
"The lamp number n of the button telephone 10-1 is the response display lamp for the central office line n of the button telephone."
or "Switch n of key telephone 10-k is a switch for requesting hold." Such individual logical information is stored, for example, in the ROM 12 of the main control device 4. The MPU 15 of the main control device 4 is, for example, a button telephone 10-
When turning on the response display lamp for office line n of key telephone 10-1, it is learned from the ROM 12 that the response display lamp for office line n of key telephone 10-1 is lamp number n, and the lamp number of key telephone 10-1 is turned on. n
The second telephone interface 9-1 converts the information into individual physical control information such as "Turn on the lamp of
Send to. Similarly, the individual physical control information sent from the second telephone interface 9-1 is converted using the individual logical information.

On the other hand, the second telephone interface 9-1
The MPU 20 converts the individual physical control information into a data format to be transmitted and received between the key telephones 10-1 to 10-n. For example, when the MPU 20 receives the above-mentioned individual physical control information "Turn on the lamp with lamp number n of the button telephone 10-1", it converts this into a predetermined data format and sends it to the button telephone 10-1. .

(Problems to be Solved by the Invention) However, in this information control method, all the control information specific to the button telephone is processed by the main control device 4, so the main control device This method has a problem in that the load is large and control that particularly requires real-time processing is impossible. In addition, as control information specific to key telephones,
Control information is exchanged between the telephone interface and the main control device via individual physical control information containing a large amount of control information for each button telephone, so the amount of information between them is large and the data transfer capacity is limited. In telephone exchange equipment and the like, there is a problem in that control information transfer that requires other real-time processing is temporarily stopped. Furthermore, due to such problems, there is a problem in that the replacement operation under the control of the main control device is hindered. In particular, the above-mentioned problem becomes noticeable in large-scale switching equipment that accommodates many key telephones.

Therefore, the present invention aims to solve these problems.

(Means for Solving the Problems) The information control system in the telephone exchange device of the present invention includes a line interface provided between a line and a line switch for setting a call path, and a line interface between the line switch and the button. A telephone exchange device comprising a telephone interface provided between the telephone and a main control device for controlling the call path switch, the line interface, and the telephone interface, the storage means in the telephone interface comprising: storing in advance individual physical information that defines a correspondence relationship between logical control information necessary for processing of the main control device and individual physical control information representing control content specific to each of the button telephones; When executing control specific to a telephone, the logical control information is derived by referring to the individual physical information based on the individual physical control information.

(Function) When controlling a key telephone from the main control device, the main control device may be
Logic control information such as "Turn on the hold lamp" is sent to the telephone interface. This logical control information has the necessary level to be processed by the main control unit. The telephone interface is
In order to convert the received logical control information into individual physical control information representing specific control contents of the button telephone, the individual logical information in the telephone interface is looked up. As a result, the telephone interface learns that the hold lamp of button telephone k is the n-th lamp, and sends individual physical control information to button telephone k that says, "Light up the n-th lamp of button telephone k." . Conversely, when transmitting control information specific to the key telephone from the key telephone to the main control device, the telephone interface receives, for example, physical control information from the key telephone k that indicates that "switch m of the key telephone k has been pressed down." The telephone interface looks up the individual logical information, and when it learns that switch m is a hold switch, sends logical control information to the main control device stating that ``the hold switch of button telephone k has been pressed down.'' The main control device performs necessary switching operations based on this logical control information.

As described above, since the conversion between logical control information and individual physical control information is performed not by the main control device but by the telephone interface, the load on the main control device is reduced. Furthermore, the logical control information not only targets individual key telephones as described above, but also includes information such as "turn on the hold lamps of all key telephones in group n".
Multiple button phones can be targeted.
As a result, the amount of information between the main control device and the telephone interface can be significantly reduced, and other control information can be easily transferred.

(Example) The present invention will be described below based on an example with reference to the drawings. The present invention is directed to a telephone exchange apparatus as shown in FIG. 3 mentioned above. FIG. 1 is a block diagram showing one embodiment of the present invention. In the same figure, 4 is a main control device, 40 is a second telephone interface, and the second telephone interface is the second telephone interface 9 in FIG.
-1. As can be seen from FIG. 1 and FIG. 3, the basic configurations of both are almost the same. The difference is that the ROM 22 is configured according to the method of this invention.
A program for driving the MPU 20 is stored, logic control information having the necessary logic level processed by the main control device 4, and specific control contents specific to the key telephones 10-1 to 10-k are stored. The point is that the RAM 19 stores individual logical information that defines the correspondence relationship with the individual physical control information that is represented.

Here, the logical control information, as described above, has the necessary logical level to be processed by the main control device 4, such as "Turn on the hold lamp of the key telephone 10-1" or "Turn on the hold lamp of the key telephone 10-1." 1
0-k hold switch is pressed down," and 1. "Turn on the hold lamp of the key telephones belonging to one group". Here, the former is referred to as individual physical control information, and the latter is referred to as common logical control information. Further, the individual physical control information represents specific control contents specific to the key telephones 10-1 to 10-k, and is the same as that used in the conventional example.

FIG. 2 is a diagram showing individual logical information stored in the RAM 19. As explained in the conventional example, the individual logical information is information indicating the functional meaning of the lamps, switches, etc. of each individual button telephone, but in this embodiment, in addition to this, it is information that indicates which group the telephone belongs to. Also includes information indicating. This figure shows the individual logical information regarding the button telephone 10-1, where a is the individual logical information regarding the lamp, b is the individual logical information regarding the switch, and c is the individual logical information regarding the group. Similarly, this information is also stored for other key telephones. Conversion between logical control information and individual physical control information is performed by looking up this individual logical information.

Next, the information control method will be explained. First, from the main control device 4 to the button telephone 10-1
The case of controlling will be explained. The MPU 15 of the main control device 4, for example,
-1, turn on the hold lamp" is sent to the MPU 20 of the second telephone interface 40 via the input/output interface 16, the control line 8-1, and the input/output interface 17. The MPU 20 looks up the individual logical information regarding the button telephone 10-1 in the RAM 19 in order to find out which lamp of the button telephone 10-1 the hold lamp in the individual physical control information is. As a result of lookup, the pending lamp is 1
When the MPU 20 learns that the lamp is the 1st lamp, the MPU 20 transmits the individual logical control information to the ``button telephone 10-1''.
This is converted into individual physical control information such as "Turn on the first lamp." Next, the MPU 20 converts this into a known data format, and sends it to the key telephone 10-1 via the data transmission/reception circuit 21.
Sends information to turn on the second lamp.

Next, a case will be described in which control information is sent from the key telephone 10-1 to the main control device 4. The MPU 20 receives, for example, individual physical control information such as "the first switch of the button telephone 10-1 has been pressed down" from the button telephone 10-1. MPU20 looks up RAM19,
We know that the first switch is a hold switch. Next, the MPU 20 converts this individual physical control information into individual physical control information such as "The hold switch of the key telephone 10-1 has been pressed down" and sends it to the MPU 15 of the main control device 4. MPU1
5 receives this individual physical control information, and controls the inside of the telephone exchange apparatus so as to perform the corresponding exchange operation.

Next, when the MPU 15 sends out the common logic control information "Turn on the hold lamp of group 1", the MPU 20 looks up the RAM 19 and determines which key telephones belong to group 1. Based on the search result, the MPU 20 lights up the hold lamp of the corresponding key telephone.

The present invention has been described above based on one embodiment.
Note that the individual logical information in the RAM 19 is stored in the MT/DK 1 of the main control device 4 during the initial setting of the telephone exchange.

(Effects of the Invention) As explained above, according to the present invention, since the conversion between logical control information and individual physical control information is performed within the telephone interface, the load on the main control device is reduced and real-time Processing can be facilitated. Furthermore, since information capable of controlling a plurality of key telephones can be used as one piece of logical control information, the amount of control information between the main control device and the telephone interface can be reduced. Therefore, the present invention is suitable for application to large-scale telephone switching equipment that handles a large amount of data.
