Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a connection method between a telephone exchange and a telephone, and particularly, a connection between the telephone exchange and a telephone terminal, a local area network (LAN) capable of using a telephone cable, or these. The present invention relates to an electronic IDF system as an integrated wiring system for cable wiring when both are used together.

As is well known, as telephone terminals, various telephones, facsimiles, personal computers and the like are connected to a telephone exchange, and information processing terminals are connected to a LAN such as an Ethernet system.

Generally, the twisted pair wire can transmit data of 10 MBPS, and the telephone and data terminals can be connected by the same cable. Therefore, the idea of prewiring, in which a twisted pair cable having a sufficient capacity is preliminarily wired as wiring for an office, is becoming established. By this, the relocation of terminals,
It is possible to lighten the burden of construction work when additional construction becomes necessary, and such investment for reducing construction costs is becoming common.

At this time, it is necessary to set the connection state between the outgoing lines from a plurality of subscriber circuits in the telephone exchange and the core wire of the telephone cable for a plurality of telephone terminals in any combination. For this purpose, a terminal board called IDF has been conventionally used.

In such an IDF, the connection state of the terminal board portion can be automatically set arbitrarily by inputting connection control information from the outside without using fixed connection such as soldering. It is convenient if you can.

[0006]

2. Description of the Related Art In order to connect a telephone exchange to a telephone terminal, a terminal board generally called an IDF or a patch panel is used, and the outgoing line from the subscriber circuit of the telephone exchange is temporarily connected to a terminal line on one side of the IDF. And connect it to the vicinity of the user's telephone by using the telephone cable from the other terminal row.

The accommodation position of the subscriber circuit in the telephone exchange is predetermined corresponding to the telephone number, and the core number of the telephone cable corresponds to the telephone of each user. Therefore, in order to accommodate any telephone in any telephone number, a desired connection state is realized by performing strap connection between the terminal row on the telephone exchange side of the IDF and the terminal row on the telephone side. To do.

As a strapping method in this case, a method of soldering connection between two specific terminals in both terminal rows with a jumper wire or a cable having modular jack terminals attached at both ends is prepared. A method of connecting by using is used.

However, in the method of setting the connection in the IDF by the strap connection as described above, not only is it time-consuming and time-consuming to set each connection, but also
When the connection state needs to be changed at a later date, it is often very laborious and time consuming.

Further, when the number of terminals in the IDF is large, the number of strap connections is also large, so that the connecting lines are messed up, not only a large space is required for wiring, but also maintenance and connection change work is difficult. It is easy to become.

Such a situation is the same when connecting each channel in the LAN to a corresponding data terminal.

[0012]

As described above, the first problem in connection between such a telephone exchange and a telephone terminal is the commercialization of parts related to cable construction and terminal connection. However, the cable handling method and the construction method are gradually being improved, but it is still necessary to leave the work to a specialist.

The second problem is that the telephone number of the telephone is
This means that it is necessary to create construction drawings in order to be able to connect an arbitrary telephone to an arbitrary telephone number from the accommodation position number, the cable core number, and the like.

The third problem is that the telephone is relocated.
It is necessary to keep track of the current wiring status and manage it at all times in preparation for expansion.

Furthermore, the fourth problem is that the space required for installing the IDF is large and a construction area is required.

The present invention is intended to solve the above problems of the prior art, and the initial cost required for the equipment can be recovered by the construction cost for several years, and thus the construction cost can be increased. It is an object of the present invention to provide an electronic IDF capable of solving the problem of space factor and reducing the number of wiring management steps.

[0036]

FIG. 5 shows an embodiment of the present invention, showing an example of the overall construction of a computerized IDF according to the present invention, in which the same components as in FIG. 1 are designated by the same reference numerals.

In FIG. 5, numbers 1 and 2 of the telephone exchange 4 are shown.
From the subscriber accommodation position of 0, Y of the matrix switch unit 2
It is connected to the terminals of numbers 01 to 20 of the terminal row 8 in the axial direction.
The telephone number can be freely set for each telephone exchange system, and is set to 201 to 220 in FIG. The telephone number of the controller unit 3 is 2
It is set to 00. In the case of FIG. 5, the number of usable telephones is 20.

The terminal numbers in the terminal row 7 in the X-axis direction of the matrix switch section 2 are 01 to 30 and have a capacity capable of connecting 30 telephones. In this way, the concept of prewiring with the capacity of the telephone set larger than that of the telephone switchboard in view of the room for expansion in the future is currently the mainstream. Is intended to be unnecessary. In the case of FIG. 5, terminal numbers 01 to 30 in the X-axis direction
Are sequentially and regularly connected to the modular jack numbers 01 to 30, and the X-axis terminal number 1 corresponds to the modular jack number 1, for example.

The cross points in the matrix switch section 2 are simply 20 × 30. It is possible to reduce the number of crosspoints by setting restrictions on selection, but there are restrictions on usage.

The controller section 3 has a first table for determining the relay number at the cross point from the X-axis terminal number and the Y-axis terminal number, and a second table for determining the correspondence between the Y-axis terminal number and the telephone number. , And a third table that defines the correspondence between the X-axis, the terminal number, and the modular jack number. As an example of the contents of the first table, the Y-axis terminal number 01 of the matrix switch unit 2 in FIG.
And the relay number for the cross point of the X-axis terminal number 01 is 0101.

FIG. 6 exemplifies a table that defines the correspondence between Y-axis terminal numbers and telephone numbers. In addition, FIG.
It is an example of a table that defines the correspondence between the X-axis terminal number and the modular jack number.

The first table for determining the relay number can be uniformly determined at the time of designing the controller section 3 by determining the capacity of the matrix switch section 2, but the second table shown in FIG. 6 and FIG. One correspondence table must be set for each system. A telephone exchange to provide,
The system provider sets the initial settings according to the contents of the cable construction. Also, when adding a line to the telephone exchange, the system provider side similarly adds table data from the maintenance terminal 13.

At the beginning of providing the system, all the relays of the matrix switch section 2 are in a restored state, so that one telephone is connected so that the user can transmit the setting information when handing over to the user. Hand over. In the example of FIG. 5, by setting the modular jack 01 to the telephone number 201, the relay of the number 0101 is delivered in a driven state.

The user connects the telephone to the modular jack of number 01, dials 200, and connects the controller unit 3. After connection, the telephone number and the modular jack number to be connected to this are paired and sequentially transmitted to the controller unit 3. Modular jack number 02-3
19 sets of 0 and 19 sets of telephone numbers 202 to 220 can be combined to set 19 sets. The controller unit 3 stores and saves the received setting information as a correspondence table of modular jack numbers and telephone numbers.

FIG. 8 exemplifies the correspondence between modular jack numbers and telephone numbers. When the number of telephones to be set is large, the system provider creates data in advance on the maintenance terminal by submitting the correspondence table filled in the format shown in FIG. 8 from the user to the system provider. Then, the controller unit 3 can be set from the maintenance terminal 13.

When the controller unit 3 receives the data in the form of the correspondence table shown in FIG. 8, the modular jack number indicates the X-axis terminal number, the telephone number indicates the Y-axis terminal number, and FIGS. The relay number of the matrix switch unit 2 is determined by drawing from the table shown, and the relay is driven.

In the example of FIGS. 6 and 7, the relay number 02
The relays are driven in the order of 02, 0303, .... When a plurality of relays are driven in the same row of the Y-axis terminal row and the X-axis terminal row of the matrix switch unit 2, multi-connection is made,
Setting is prohibited. However, when the ISDN interface is adopted, it is possible to specify the telephone number of the corresponding ISDN interface in the X-axis direction. For example, if the telephone number 220 is an ISDN interface, 20
By simultaneously driving the 01, 2002 and 2003 relays, a plurality of telephone terminals can be connected to the 220 line.

When it is necessary to replace the telephone numbers due to the organization change or office layout change while operating with the setting information shown in FIG. 8, the setting number to be changed is transmitted from the nearest telephone. As a result, the telephone can be easily relocated.

For example, when the telephone number 202 is set for the modular jack number 30 (unconnected), the modular jack number 30 and the telephone number 202 are transmitted from the nearest telephone to the controller unit 3.
The relay 0230 is driven to restore the relay of 2002.

As described above, it is possible to easily relocate the telephone, but from a management point of view, there is a risk that someone may arbitrarily operate to change the connection setting. Therefore, when the telephone is connected to the controller unit 3, the controller unit 3 may be provided with a function of checking the qualification of the operator by using a personal identification number or an ID card on the telephone side.

FIG. 9 shows an example of the configuration of the controller section, in which the same elements as those in FIG. 5 are indicated by the same numbers, and 21 is a communication interface (INF) for communicating with the telephone exchange subscriber line. ), 22 is a bus, 23 is a central processing unit (CPU), and 24 is a read only memory (R).

RL0101 to RL01n, RL0201
˜RL02n, ... There is. The contacts of these relays respectively correspond to the same numbered cross points shown in FIG.

In the controller unit 3, the communication INF2
1 communicates with the telephone exchange subscriber line and stores the received information in the RAM of the memory 24. The matrix SWINF 25 outputs the information accumulated in the memory 24 to the matrix switch unit 2 via the X-axis relay driver 26 and the Y-axis relay driver 27. The CPU 23 uses a program stored in the ROM of the memory 24 to perform these processes.

In the X-axis relay driver 26, the decoder driver 28 decodes the relay drive signal composed of the serial signal from the matrix SWINF 25, energizes the designated relay coil, and turns on the corresponding contact. Similarly, in the Y-axis relay driver 27, the decoder driver 28 decodes the relay drive signal composed of the serial signal from the matrix SWINF 25, energizes the designated relay coil, and turns on the corresponding contact. As a result, a current flows from the power supply 30 to the relay coil connected between the turned-on X-axis relay contact and the turned-on Y-axis relay contact, and turns on the corresponding relay contact. As a result, the telephone or the data terminal is connected via the crosspoint designated by the X-axis terminal number and the Y-axis terminal number as described above.

[0056]

As described above, according to the present invention, in a terminal board for connecting an upper line and a terminal such as a telephone in an arbitrary relationship, a desired connection state can be established by inputting information from the outside. It can be set arbitrarily. Therefore, according to the present invention, a user can easily move a terminal such as a telephone,
It is possible to add more.

In recent years, office layout changes have occurred in some form in 30% of companies every year, and the construction costs associated with the relocation and extension of terminals such as telephones are enormous. .. Especially, most of the construction cost is personnel cost, so it is increasing year by year.
According to the present invention, a certain amount of initial cost is required, but it is possible to recover the initial cost in a few years as compared with the annual construction cost thereafter. Further, with the advance of semiconductor technology, it is expected that the relay section constituting the matrix switch section in the IDF of the present invention will be drastically reduced in price, and therefore the economic effect of adopting the present invention is extremely large. It appears to be.
