Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information-compatible house in which an analog telephone, an ISDN connection device and a personal computer connected to a LAN can be used in a plurality of rooms of a house, and in particular, these information terminals are used in each room. The present invention relates to a house that is characterized by the advance wiring of a communication cable placed in a wall or under a floor to enable the wiring.

[0002]

2. Description of the Related Art With the rapid spread of ISDN, the Internet, and personal computers, a situation in which a plurality of types of information terminals are used in a general household is occurring. For example, a plurality of telephones, facsimile terminals, personal computers connected to the Internet via ISDN, and the like are being installed in homes. The location may be moved or added in accordance with changes in the environment or the growth of children. These information terminals require connection of communication cables such as analog telephone cables and ISDN cables, which are usually connected to a public ISDN line via a terminal adapter (TA), a digital service unit (DSU) and a security device. You. A TA generally has a plurality of analog ports (AP ports) and digital ports (ST ports).
A G3 facsimile, a personal computer via a modem, etc. are connected in a star connection or a bus connection. On the other hand, G4
Facsimile, PC, etc. are connected by bus. The communication speed of the ST port is higher than that of the AP port, and is not easily affected by noise.

[0003] Therefore, when installing a plurality of information terminals in a home, it is necessary to install one DSU built-in TA and lay an analog telephone cable or ISDN cable from the TA to each information terminal. become. Therefore, when a plurality of information terminals are installed in a house, a large number of cables for connecting to the devices are laid, which is very unsightly. In addition, when moving or adding an information terminal, it is necessary to move or add a communication cable, which is very complicated. Cables connecting these devices include 2N-core, 4-core, 6-core and 8-core cables.
An analog terminal and an ISDN terminal are different in the shape and the number of poles of a modular jack (MJ) provided at a cable end, so that erroneous wiring is likely to occur.

[0004] These communication cables are upwardly compatible, and if the connection to the terminal is not mistaken, an 8-core cable is replaced with a 4-wire cable.
It is possible to use it as a core cable or to use a 4-core cable as a 2N core cable. The reason why the shape of the MJ differs between analog and ISDN is to avoid erroneous insertion. If the corresponding jack and plug are of the same standard, the analog MJ (jack called RJ-11) is often used. ) Instead of digital MJ (R
J-45 is often used). It should be noted that an 8-core cable is used in a LAN described later, and an MJ for connection is used.
Uses the same RJ-45 jack as that for ISDN (however, the connection form to the terminals is different).

In order to solve the above-mentioned problem, ie, the problem of having to lay a large number of communication cables indoors and to move or add these cables every time an information terminal is moved or added, an analog MJ is installed in each room. And M for digital
J is provided, and analog and digital communication cables for connecting the MJ of each outlet and the TA connected to the ISDN line are laid in advance in the wall or under the floor of the building. Wiring (for example, see Japanese Patent Application Laid-Open Nos. 9-224073 and 9-153926).

FIG. 11 shows such a prior art.
become that way. FIG. 11 shows an example in which analog terminals are connected to a bus.
No.-224073). In the figure, one information distribution board (referred to as such in accordance with a commercial power distribution board) 1 is usually installed at one location of a house. The information distribution board 1 is equipped with a DSU built-in terminal adapter 10 and is connected to a public ISDN line 4 through a protector 3. The terminal adapter 10 has a plurality of analog ports (analog MJ) 13 and an ISDN port (digital MJ) 14.

In each room in the house, an information communication outlet 5 provided with a digital port 51 and an analog port 52 is arranged in anticipation of future needs. At present, these ports are RJ-11 type jacks and RJ-45 type jacks, but the cable connection terminals on the back of these jacks are U-shaped crimp terminals. Therefore, a terminal plate 8 provided with a large number of U-shaped crimp terminals is provided in the information distribution board 1, and the terminals of this terminal plate and the MJ of each outlet are divided into digital and analog ones and the corresponding communication cables 6 are provided. Connect with. In the example shown in the drawing, outlets are appropriately allocated by two bus lines and connected to the TA so that two analog lines can be used separately.

The communication cable 6 is arranged in a wall or under a floor as a preceding wiring when a house is newly constructed or expanded. Since the port of the terminal adapter is MJ and the terminal of the terminal plate is a U-shaped crimp terminal between the terminal adapter 10 and the terminal plate 8 in the information distribution board 1, the rosette 8
1, the terminal adapter 10 and the rosette 81 are connected by a cord having MJ connected to both ends, and the U-shaped crimp terminals of the rosette 81 and the terminal plate 8 are connected by a connection cable 82. One rosette 81 is required for each bus line.

If wiring for communication as shown in FIG. 11 is provided as a preceding wiring in a wall when a house is newly constructed, for example, when a telephone or a personal computer to be connected to the Internet is moved or added, these devices are used. By simply plugging the signal line into the analog port 52 or the digital port 51 of the information communication outlet 5 arranged in advance, those devices can be used immediately.

[0010]

However, in the conventional prior wiring as described above, the communication terminals connected to the digital port and the analog port of the information communication outlet arranged in each room are respectively digital or analog. If there is only one digital port and one analog port, for example, if you want to use two analog terminals in one room, one communication terminal is not used in another room. If you don't connect a cable to the analog port, you cannot use it.

Since the front face of the information communication outlet is exposed, it is possible to replace the digital MJ with the analog one even after the installation, but replace the preceding wiring in the wall. Since it is impossible to do so, the number of analog ports and digital ports in each room is determined when the preceding wiring is laid, and cannot be changed thereafter. Further, it is difficult to predict in which room and how many information terminals will be used in the future. So in order to cope with possible future situations, as many digital and analog ports as possible must be placed in as many rooms as possible, and in reality many of them remain unused That is very expensive.
The ISDN cable has a draw-out length from TA of 200
m, it may not be possible to provide digital ports in a large number of rooms or locations due to the length limitation.

In recent years, a plurality of personal computers have been installed in homes, and there are many cases of connecting them to a LAN.
It is considered that personal computers LANs in general households are becoming more widespread due to lower prices of personal computers and increase of information stored in personal computers. A personal computer connected to a LAN is normally star-connected to a hub with an 8-core cable. IS LAN
When connecting to a DN, a router (with a built-in hub) is connected to the digital port of the TA. Recently, DSU, TA,
A TA is provided in which a router and a hub are all integrated. The MJ used for these connections is the M for ISDN.
Although it has the same shape as J, the personal computers cannot be connected to each other by LAN using the bus wiring for ISDN due to the difference between the used contacts and the star connection and the bus connection.

[0013] Therefore, in order to perform pre-wiring in anticipation of the future establishment of a home LAN, a LAN port is added to each information communication outlet, and a communication cable for connecting each LAN port to a hub or router is required. It is necessary to add additional wiring, for analog, IS
If it is not possible to predict how many devices for DN and LAN will be placed in which room in the future, these three types of wiring must be provided in as many rooms as possible. The amount of wiring and the cost and effort required for it are extremely wasteful.

Therefore, according to the present invention, at least a digital port of an information communication outlet provided in each room is connected to an IS port.
It can be changed between DN and LAN, and it is also possible to replace the MJ of the information communication outlet or to connect an analog terminal connection cable with a digital modular plug connected to one end and an analog MJ connected to the other end. It is an object of the present invention to provide an information-capable house provided with advance wiring that can switch digital wiring to analog wiring by using the same.

[0018]

FIG. 1 to FIG. 6 show a first embodiment of the present invention. In the following description and in the claims, an N-pole jack, a 2N-pole jack, an N-pole jack,
N when referring to a core cable, a 2N core cable, or the like means an integer greater than the number of terminals required for connecting a bus terminal and the number of terminals required for connecting a star terminal does not exceed 2N. The N-pole jack and the 2N-pole jack are jacks having the number of contacts of N and 2N or more, respectively, and the N-core cable and the 2N-core cable are cables having the number of core wires of N and 2N or more, respectively. Considering typical terminals, cables and connectors (mainly MJs) currently used, it is practical to set N to 4 at present.

In FIG. 1, an information distribution board 1 is installed adjacent to a telephone line entrance of a building. Information distribution board 1
A terminal adapter 10 including a DSU 11 and a router 12 and a cable connection unit 2 are provided. The built-in DSU 11 is connected to the public ISDN line 4 via the protector 3. The terminal adapter body has a plurality of analog ports (AP ports) 13 and an ISDN port (ST port) 14, and one of the ISDN ports 14 is connected to a built-in router 12, and the built-in router 12 has a plurality of LANs.
A port 15 is provided. In a current typical terminal adapter, the analog port 13 is an RJ-11 type M
J, ISDN port 14 and LAN port 15 are RJ-
It is a 45 type MJ.

From the above situation, in this embodiment, 2N
An RJ-45 type jack is used as the pole jack, and an RJ-11 type jack is used as the N pole jack. RJ
The -45 type jack has 8 poles, and the RJ-11 type jack has 6 poles, and two of the six poles are used.

An information communication outlet 5 is arranged in a necessary room of the building. Each information communication outlet 5 is practically provided with a plurality of analog ports and digital ports. However, in the figure, the analog port is omitted and only one digital port is shown. The digital port 51 is a 2N-pole jack.

The cable connection unit 2 of the information distribution board 1 has a patch cord connection port 21 corresponding to the digital port 51 of each information communication outlet 5 on a one-to-one basis, and a termination jack 22 to which a termination resistor is connected. Is provided. Each of the patch cord connection port 21 and the termination jack 22 is a 2N-pole jack.

Each jack 21 of the cable wiring unit 2
And the jack 51 of the information communication outlet are divided into N poles and connected one-to-one with a 2N-core communication cable 6. The cable connection terminals on the back of the RJ-45 jack used as these jacks are U-shaped crimp terminals. Out of the 2N contacts of the jacks 21 and 51, N is defined as the sending side, and the other N are defined as the returning side, and the core wire of the cable connected to the sending side contact is connected to the sending side core wire and the return side contact. The determined core wire is defined as the return core wire. This cable 6
It is wired inside the wall and cannot be replaced after it has been laid.

The 2N pole plug of the bus terminal connected to the terminal connection port 51 of the information outlet has the sending terminal and the return terminal internally short-circuited. If the terminal maker does not provide such a plug, it is necessary to change the core of the communication cable at the U-shaped crimp terminal on the back of the terminal connection when converting between star connection and bus connection become. That is, the terminal connection port 51 for connecting the bus connection terminal
Short-circuits the feed-side core wire and the return-side core wire at the U-shaped crimp terminal. Terminal connection port 5 for connecting a star connection terminal
1 connects the sending-side core wire and the returning-side core wire to the corresponding sending-side terminal and returning-side terminal, respectively, without short-circuiting the two. This operation can be easily done by removing the information outlet from the wall and pulling out the communication cable a little.

Terminal adapter 10 in information distribution board 1
Patch cord 23 consisting of a 2N core cable having 2N pole plugs 26 attached to both ends, and an N pole plug 27 at the base end.
And 2N pole plugs 26a to 26
e and a second patch cord 24 to which 26f is attached. 2N pole plug 26 in the middle of the second patch cord
The numbers a to 26e are set to the maximum number of terminals connected to the bus. This second patch cord is an N-core cable, and a first intermediate plug (2N pole) 26
a on the feed side, and the following intermediate plugs 26a to 26
e are connected so as to connect the return side contact of the upstream side (line controller side) intermediate plug to the feed side contact of the downstream side intermediate plug, and terminate the return side contact of the last intermediate plug 26e. It is connected to the feed side contact of the plug 26f. Nothing is connected to the return contact of the terminal plug 26f. The reason why a 2N-pole plug is used while the termination plug 26f uses only the N pole is to enable connection of an arbitrary intermediate plug and termination plug to the termination jack 22.

In the preceding wiring state, the star connection terminal (LAN terminal) 71 is connected to 5a and 5c of the information communication outlets 5a to 5e, and the remaining 5
b, 5d and 5e are bus connection terminals (ISDN terminals) 72
You want to connect. At this time, of the patch cord connection ports 21 of the cable connection unit corresponding to each information communication outlet, 21a and 21c are connected to the first patch cord 2
At 3, each is individually connected to the LAN port 15 of the terminal adapter. The remaining patch cord connection ports 21b, 21d, and 21e of the cable connection unit have the intermediate plug 26a of the second patch cord in which the base N-pole plug 27 is connected to the ISDN port of the terminal adapter.
26c are sequentially inserted, and the intermediate plug 26d next to the intermediate plug inserted into the patch cord insertion opening 26e is connected to the termination jack 22. The remaining intermediate plug 26e and terminal plug 26f are not connected anywhere. Then, the information outlet to which the bus connection terminal is connected is pulled out, and the sending core wire and the return core wire of the communication cable are short-circuited.

It is apparent that the star connection terminal 71 is star-connected to the line controller 10 in this state. On the other hand, the bus connection terminals 72 are connected between the outgoing side and the return side of the 2N core cable 6 connecting the information communication outlet 5 and the cable connection unit 2 and the intermediate plug of the second patch cord 24 (this portion is N-core). Is connected via a bus). To switch the star connection and the bus connection of each information communication outlet, the 2N pole jacks 21a to 21e of the corresponding cable connection units are individually connected to the star connection port 15 of the line controller by the first patch cord 23. Or the second patch cord 24
The connection can be made by connecting to the intermediate plug 26.

For example, when the information communication outlet 5a is to be switched for bus connection, the first patch cord 23 is pulled out from the 2N-pole jack 21a of the cable connection unit, and the intermediate plug 26 connected to the terminal jack is disconnected.
d may be inserted into the 2N pole jack 21a, and the next intermediate plug 26e may be inserted into the terminal jack 22. 5
In order to be able to use all five connection ports of one information communication outlet for star connection or for bus connection, there are five star connection ports on the line controller 10 side; 5 first patch cords 23,
A second patch cord 24 with five intermediate plugs
It is necessary to have a book. If such a thing is prepared, without changing the communication cable 6 between the cable connection unit 2 and each outlet 5a to 5e, it is possible to freely determine which outlet is used for star connection and which outlet is used for bus connection. You can choose.

When an analog connection terminal is connected to the digital port 51 of the information communication outlet 5, a third patch cord 25 is prepared. The third patch cord 25 has an RJ-11 on the proximal end for connecting to a terminal adapter.
This is a two-core cord with a type jack connected and an RJ-45 jack connected to the other end. In addition, R of information communication outlet
To connect an analog terminal to the J-45 jack,
And the same patch cord 25 is used in reverse.

FIGS. 7 to 10 show the second embodiment. Currently used communication cables are a LAN cable having eight cores, an ISDN cable having four cores, and an analog cable having two cores.

The embodiment shown in FIG. 7 uses an RJ-11 type jack as the patch cord connection port 21 arranged in the cable connection unit 2. This has 8 core LA
When connecting N cables, two adjacent patch cord connection ports are used in parallel. First patch cord 23
Has an RJ-45 plug 26 attached to the base end connected to the router, and two RJ-11 plugs 27 attached to the other end.

Each information communication outlet 5 has an RJ-4
A 5 jack (digital port) 51 and an RJ-11 type jack (analog port) 52 for connecting an analog terminal are provided, and the analog connecting jack of each outlet is connected to the analog port 13 of the terminal adapter by a conventional connection structure. The RJ-45 jack 51 of each outlet is
Connect two RJ-11 type jacks of the cable connection unit with two 4-core cables or one 8-core cable.

The second patch cord 24 for connecting the wiring to the bus is formed by a plurality of cords having RJ-11 plugs attached to both ends. Two adjacent RJ-11 type jacks of the cable connection unit 2 are determined to be one on the sending side and the other on the returning side in consideration of the connection of the bus terminal. The plurality of second patch cords 24 are connected to the ISJ port 14 of the terminal adapter by one and connected to the sending side of an RJ-11 type jack corresponding to an outlet to be bus-connected, and the RJ-11 plugs are sequentially connected. A four-core cable is used to connect the return side of the upstream RJ-11 type jack to the downstream side of the RJ-11 type jack, and then to the return side of the last RJ-11 type jack. RJ-11 type jack with a terminating resistor (terminating jack)
22 is connected.

When it is desired to use the RJ-45 jack of the outlet for analog device connection, a third patch is provided between the RJ-11 type jack on the sending side of the cable connection unit corresponding to the outlet and the analog port 13 of the terminal adapter. Connect with a cord (two-core cable with RJ-11 plugs attached to both ends) and connect nothing to the RJ-11 type jack on the return side corresponding to the outlet.

In the example of FIG. 7, a pair of RJ-11 type jacks provided in the cable connection unit correspond to one RJ-45 jack of the information communication outlet, so that the cable connection unit 2 becomes large. However, there may be a case where the unit price of the MJ or the cable is advantageous in terms of cost.
