BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information control system in a telephone exchange, and more particularly to a system for controlling information between a main control unit in a PBX or the like and a telephone interface that accommodates a key telephone.

[0002]

2. Description of the Related Art FIG. 3 shows a block diagram of a telephone exchange device which accommodates a key telephone and a main telephone. In the figure, the telephone exchange device 1 has a star-like configuration via line interfaces 2-1 to 2-n provided for the lines, a call path switch 3 for setting a call path, and extension cables 7-1 to 7-k. First telephone interface 5-1 and extension lines 11-1 to 11 provided for each of the main telephones (DP dial type and PB dial type) 6-1 to 6-k provided in
Button telephone provided in a star shape via -k (here, in order to provide a wide variety of services, a telephone with display functions such as multiple lamps and displays, multiple switch operation functions, etc. (Defined to include a control device such as an MPU) 10-1 to 10-k provided with a second telephone interface 9-1 and a main control device 4 for controlling each part of the telephone exchange device 1. It is configured to include. 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 is passed. The main control information is an on-hook / off-hook signal, a dial number signal, various signal tone transmission time timing signals, and the like. Further, the control information peculiar to the key telephone set passing through the control line 8-n includes a blinking signal of a lamp provided in the key telephone set, switch pressing information, and display control information of the 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.

Now, referring to FIG. 4, the main controller 4
A method of processing control information unique to the key telephones 10-1 to 10-k performed between the second telephone interface 9-1 and the second telephone interface 9-1 will be described. FIG. 4 is a block diagram showing the main configuration of the main control device 4 and the second telephone interface 9-1. In the figure, 12 and 18 are read-only memories (hereinafter referred to as ROM), 13, and
19 is a random access memory (hereinafter referred to as RAM),
14 is a mass storage device (indicated by MT / DK in the figure), 1
Reference numerals 5 and 20 are microprocessor units (hereinafter referred to as MPUs), 16 and 17 are input / output interfaces, and 21 is a data transmission / reception circuit. As the control information unique to the key telephone set passing through the control line 8-n, a control signal specifying the lamp number and switch number of each key telephone set is used. Here, these pieces of information are referred to as individual physical control information. For example, from the main control device 4 to the second telephone interface 9-1, the individual physical control information "Turn on the lamp with the lamp number n of the button telephone 10-1" is sent, and the second telephone interface 9-1 sends the main physical control information. The individual physical control information "The switch of the switch number n of the key telephone set 10-k is pushed down" is sent to the control device 4. In the main controller 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 sent to the individual logical information. Using,
It is converted into logic level information suitable for the main controller 4 to process. This corresponds to the logic control information described later. Here, the individual logic information is information indicating the functional meaning of the lamps and switches of each key telephone.
For example, information such as "the lamp number n of the key telephone set 10-1 is a response display lamp of the office line n of the key telephone set" or "the switch n of the key telephone set 10-k is a hold request switch". Is. Such individual logic information is stored in the ROM 12 of the main control device 4, for example. When the MPU 15 of the main control unit 4 turns on the response display lamp of the station line n of the button telephone 10-1 for example, the response display lamp of the station line n of the button telephone 10-1 from the ROM 12 is the lamp number n. Knowing that, the individual physical control information of "Turn on the lamp of lamp number n of the key telephone set 10-1" is converted to the second physical control information.
It is sent to the telephone interface 9-1. Similarly, the individual physical control information transmitted 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 sends the individual physical control information to the key telephone 10.
-1 to 10-n is converted into a data format to be transmitted and received. For example, when the MPU 20 receives the above-described individual physical control information "Turn on the lamp of the lamp number n of the key telephone set 10-1", it converts this to a predetermined data format and sends it to the key telephone set 10-1.

[0005]

However, in such a control method of information, since the processing of the control information peculiar to the key telephone is all performed by the main control device 4, the load of the main control device is reduced. There is a problem that the control that requires a real-time processing becomes impossible.
Also, as the control information unique to the key telephone, the control information is exchanged between the telephone interface and the main control unit through the individual physical control information, which has a large amount of control information for each key telephone. However, there is a problem that transfer of other control information, which requires real-time processing, is temporarily stopped in a telephone exchange device or the like which has a large data transfer capacity. Further, there is a problem that the replacement operation under the control of the main control device is hindered due to such a problem. In particular, in a large-scale exchange apparatus that accommodates many key telephones, the above problem becomes remarkable.

Therefore, the present invention aims to solve these problems.

[0007]

An information control system in a telephone exchange apparatus according to the present invention comprises a line interface provided between a call path switch for setting a call path and a line, the call path switch and a button telephone. A telephone interface provided between the call path switch,
In a telephone switching device having a line interface and a main control device for controlling a telephone interface, the storage means in the telephone interface has logical control information necessary for processing of the main control device and necessary for controlling the key telephone. In the case where the main control device stores in advance information corresponding to various individual control information and common logical information designating a group for each key telephone, and the main control unit executes control unique to the key telephone, the individual logical control In the case where the key telephone is controlled by deriving individual physical control information based on the information, and the main controller causes one or a plurality of the key telephones to perform common control, one common logical control is performed. From the common logical control information at the phone interface by sending information Belonging to the group as a control object 1
Alternatively, a plurality of key telephones are determined, and the individual physical control information for each key telephone is derived based on the common logical control information so that one or more key telephones can be controlled simultaneously.

[0008]

When controlling the key telephone from the main control unit, the main control unit sends to the telephone interface logical control information, for example, "light the holding lamp of the key telephone k." This logic control information has the level required to be processed by the main controller. The telephone interface looks up the individual logical information in the telephone interface in order to convert the received logical control information into individual physical control information representing the specific control contents of the button telephone. As a result, the telephone interface knows that the holding lamp of the key telephone k is the nth lamp, and sends the individual physical control information "Turn on the nth lamp of the button telephone k" to the key telephone k. Conversely, when transmitting the control information unique to the key telephone from the key telephone to the main control unit, the telephone interface is, for example, from the key telephone k to “key telephone k
Physical switch information is received. The telephone interface looks up the individual logical information, and when it knows that the switch m is the hold switch, "the hold switch of the button telephone k is pushed down."
Is sent to the main controller. The main control unit performs the necessary exchange operation based on this logical control information.

As described above, since the conversion of the logical control information and the individual physical control information is performed not by the main control unit but by the telephone interface, the load on the main control unit is reduced and the real-time processing is facilitated. Further, the invention not only targets individual key telephones as described above as the logic control information, but also, for example, "lights all hold lamps of key telephones in group n".
Multiple key telephones can be targeted. As a result, the amount of information between the main controller and the telephone interface can be significantly reduced, and other control information can be easily transferred.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described based on an embodiment with reference to the drawings. The present invention is directed to the telephone exchange apparatus as shown in FIG. FIG. 1 is a block diagram showing an embodiment of the present invention. In the figure, 4 is a main controller, 40 is a second telephone interface, and this second telephone interface corresponds to the second telephone interface 9-1 in FIG. As can be seen from FIG. 1 and FIG. 3, the basic configurations of both are almost the same. The difference is R
The OM 22 stores a program for driving the MPU 20 according to the method of the present invention, logic control information having a necessary logic level to be processed by the main controller 4, and key telephones 10-1 to 10-k. That is, the RAM 19 stores the individual logical information that defines the corresponding relationship with the individual physical control information that represents the specific control content unique to the.

As described above, the logic control information has a logic level necessary for being processed by the main control unit 4, such as "turn on the hold lamp of the key telephone 10-1". For individual key telephones such as "the hold switch of the key telephone 10-k is pressed down" and "group 1 (a group is a plurality of key telephones divided into several groups. "Turn on the hold lamp of a key telephone belonging to one of the groups"), and here the former is called individual physical control information and the latter is common logical control information. That. Also,
What is individual physical control information? Key telephones 10-1 to 10-k
Represents the specific control content unique to the above, and is the same as that used in the conventional example.

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

Next, the information control method will be described. First, the case of controlling the key telephone set 10-1 from the main control device 4 will be described. M of the main controller 4
The PU 15 transmits, for example, the individual physical control information "Turn on the holding lamp of the key telephone 10-1" to the M of the second telephone interface 40 via the input / output interface 16, the control line 8-1, and the input / output interface 17.
It is sent to the PU 20. The MPU 20 looks up the individual logical information relating to the key telephone 10-1 of the RAM 19 in order to search for the number of the lamp of the key telephone 10-1 in the individual physical control information. When the hold lamp is the first lamp as a result of the lookup, the MPU 20 gives the above-mentioned individual logical control information to "light the first lamp of the button telephone 10-1."
Is converted into individual physical control information. Next, MPU20
Converts this into a known data format and sends the information for turning on the first lamp to the key telephone set 10-1 via the data transmission / reception circuit 21.

Next, a case where control information is transmitted from the key telephone set 10-1 to the main control unit 4 will be described.
The MPU 20 receives, for example, “the first switch of the button telephone 10-1 has been pressed” from the button telephone 10-1.
The individual physical control information is received. MPU20 is RAM
Look up 19 and see that the first switch is the hold switch. Next, the MPU 20 converts this individual physical control information into individual physical control information that "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. When the MPU 15 receives this individual physical control information, it controls the inside of the telephone exchange so as to perform the exchange operation corresponding to this.

Next, when the MPU 15 sends the common logic control information "Turn on the hold lamp of group 1", the MPU 20 looks up the RAM 19 to find out which key telephone set belongs to group 1. M
The PU 20 turns on the hold lamp of the corresponding key telephone based on the search result.

The present invention has been described above based on an embodiment. The individual logical information in the RAM 19 is downloaded to the RAM 19 from the information stored in the MT / DK 14 or the ROM 12 of the main control device 4 at the time of initial setting of the telephone exchange device.

[0017]

As described above, according to the present invention,
Since information that can control a plurality of key telephones can be used as one logical control information, the control information between the main control device and the telephone interface can be reduced. Therefore, the present invention is suitable for application to a large-scale telephone exchange device having a large amount of data.

That is, according to the present invention, even in a large capacity system, different switches and lamps can be set for each key telephone, and various grouping settings can be set for each key telephone. Also, by using the common logical control information, the amount of information transmitted and received between the main control unit of the telephone exchange and the key telephone interface is greatly reduced, and the load of the main control unit is significantly reduced.
