Description

Multiplexer complex and method for constructing an indoor network using it}

The present invention relates to a communication multiplexer, and more particularly, to an integrated multiplexer for multiplexing various communication lines including voice communication and data communication, and an indoor communication network installation method using the same.

Conventionally, data communication is mainly performed in a work space, but in recent years, various computer communications including the Internet have been spreading into residential spaces.

Data communication in the home is not limited to computer communication, and the concept of so-called home automation or intelligent housing is introduced, and remote control of various home appliances has been attempted, and almost all home appliances have become a communication terminal.

Currently, telecommunications providers supply homes with two-wire and one-wire lines. Two-wire and one-wire lines are commonly used in traditional public telephone networks, so they are often referred to as "voice communication lines." One-channel cable is commonly referred to as a "data communication line" because it is a method that is recently used as data communication.

What is referred to as a voice communication line is not intended to be limited to being used only for voice communication, such as a telephone, but may be used for data communication through various modems.

In general, each household subscribes to one or more voice communication lines and one line of data communication lines. Two or more communication terminals may be connected in parallel to one communication line drawn indoors.

Parallel connection in the conventional voice communication line was made by connecting the lines directly without using a separate connector. In such a parallel connection, if one communication terminal uses a communication line, the other communication terminal cannot. That is, when two telephones are connected to one communication line, if one telephone uses the communication line, the other telephone cannot use the communication line. At this time, the conversations of the telephones in the call continue to crosstalk to other telephones connected in parallel. There is no problem because the handset of the telephone does not operate when the hooks of the telephones are turned off.

However, in data communication, such crosstalk may cause a malfunction of other terminals connected in parallel. In addition, it is common for a terminal connected to data communication to occupy a communication line for a long time, and some terminals continue to occupy the communication line and receive a signal intermittently. That is, since the communication of the data communication terminal is difficult for the user to manually control the occupancy time, a multiplexer or a connection device such as a hub or a switching hub should be used. The multiplexer is composed of one uplink port and a plurality of downlink ports, a data communication line is connected to the uplink port, and a plurality of data communication terminals are connected to the downlink port.

The control element of the multiplexer appropriately adjusts when the data communication terminals connected to the plurality of downlink ports use the communication line connected to the uplink port, and suppresses crosstalk between the data communication terminals in parallel.

As described above, in addition to computers, almost all home appliances are becoming communication terminals, so it is impossible to connect and connect a separate communication line for each home appliance, so the demand for the multiplexer in the home is increasing rapidly.

In addition, as described above, the control element of the multiplexer serves to properly control when a plurality of terminals use a single communication line, and such control fails due to several causes such as congestion or overload of communication data. You will fall in love with it. In this case, if the power supply to the control element is cut off and then supplied again, the communication failure state is eliminated and normal operation is performed.

Therefore, the user who is aware of the incommunication state should remove the incommunication state by unplugging and plugging the feed plug connected to the multiplexer, or by turning off and on the on / off switch for the feed control. By the way, this operation is cumbersome, but it can shorten the life by turning on and off the power to other components in addition to the control element of the multiplexer.

On the other hand, the cause of the communication failure may be a variety of causes, such as failure of the communication terminal, failure of the multiplexer or disconnection of the communication line or failure of the equipment of the communication service provider.

The failure of the communication terminal can be easily grasped since communication will be possible from other terminals except the failed terminal. However, the failure of the multiplexer and the failure of the communication line side are not easily identified. If the multiplexer is malfunctioning, communication may be possible by directly connecting the communication line, which is introduced indoors, to the communication terminal without passing through the multiplexer, but the extension line is extended to the position where the terminal is located or the terminal is moved to the position where the end of the incoming line is located. Is generally not easy.

Meanwhile, many multiplexers of data communication lines have been developed, and branch connectors for voice communication lines are poorly developed.

As described above, voice communication lines are also used for data communication. In particular, most home appliances have been developed such that remote control is performed through voice communication lines. Therefore, the demand for branch connectors of voice communication lines is increasing rapidly.

The integrated multiplexer is generally installed in the generation terminal box and connected to the load terminal. Since the cable is connected to the side of the UTP cable, it is not easy to work and it is difficult to secure the radius of curvature of the cable. If it is refracted, it may cause a slowdown in high-speed data transmission and reception. Therefore, it is necessary to keep the cable bent below an appropriate curvature while facilitating the cabling work.

The present invention has been made in view of the prior art as described above, and is intended to provide an integrated multiplexer including a branch connector for integrally connecting a plurality of terminals using a communication line.

Still another object of the present invention is to provide an integrated multiplexer that can easily identify the cause of communication failure, and can quickly recover communication of an urgent communication terminal when the identified cause is a failure of the multiplexer.

It is another object of the present invention to provide an integrated multiplexer which can simply reset only the control elements of the multiplexer in case of data communication failure.

The present invention also relates to a method for installing an indoor communication network using the integrated multiplexer described above.
