Description

本発明は、通信事業者の通信局舎に配置される局側通信装置と、通信局舎から遠隔に配置される通信多重装置との間で、通信多重装置に収容される複数のユーザ（通信サービス加入者）の端末側通信装置に対応する信号を多重伝送する通信システムおよび通信多重装置に関する。 The present invention relates to a plurality of users (communications) accommodated in a communication multiplexer between a station-side communication apparatus arranged in a communication station of a communication carrier and a communication multiplexer arranged remotely from the communication station. The present invention relates to a communication system and a communication multiplexing apparatus that multiplex-transmits a signal corresponding to a terminal subscriber side communication apparatus.

πシステム（非特許文献１）やＣＴ−ＲＴシステム（非特許文献２）は、局側通信装置と通信多重装置との間で、通信多重装置に収容される複数の端末側通信装置に対応する信号を多重伝送する通信システムであり、電話やＩＳＤＮサービスなどを提供している。この場合の通信多重装置は、ＯＮＵ（Optical Network Unit) やＲＴ（Remote Terminal)と呼ばれる。なお、システム構成の概観は、図１に示す本発明の通信システムと同様である。 The π system (Non-Patent Document 1) and the CT-RT system (Non-Patent Document 2) correspond to a plurality of terminal-side communication devices accommodated in the communication multiplex device between the station-side communication device and the communication multiplex device. It is a communication system that multiplex-transmits signals, and provides telephones and ISDN services. The communication multiplexing apparatus in this case is called ONU (Optical Network Unit) or RT (Remote Terminal). The overview of the system configuration is the same as that of the communication system of the present invention shown in FIG.

通常の電話回線では、通信局舎（電話局）からユーザ宅内の電話機に至るまでの間はメタリック線路設備で接続されており、電話機に対して通信局舎（電話局）に設置された装置から給電を行っている。しかし、上記のπシステムやＣＴ−ＲＴシステムは、局側通信装置と通信多重装置との間が光ファイバで接続されているために、局側通信装置から通信多重装置に給電を行うことができない。 In a normal telephone line, the connection from the communication station building (telephone station) to the telephone in the user's house is connected by a metallic line facility, and from the equipment installed in the communication station (telephone station) to the telephone Power is being supplied. However, the above-mentioned π system and CT-RT system cannot feed power from the station side communication device to the communication multiplexing device because the station side communication device and the communication multiplexing device are connected by an optical fiber. .

πシステムでは、通信多重装置（ＯＮＵ）は柱上や集合住宅の壁面に設置されるが、特に柱上に設置される場合には設置場所に給電設備がない場合が一般的である。このため、非特許文献１に示すように、電力会社からＨＵＢ給電装置に対して給電を行い、ＨＵＢ給電装置から複数のＯＮＵに対して新たに設置する給電線を介して給電を行う方法がとられている。また、ＣＴ−ＲＴシステムにおける通信多重装置（ＲＴ）も同様に屋外に配置され、設置場所において新たに給電設備を設ける必要があった。 In the π system, a communication multiplex unit (ONU) is installed on a pillar or a wall surface of an apartment house. In particular, when installed on a pillar, there is generally no power supply facility at the installation location. For this reason, as shown in Non-Patent Document 1, there is a method in which power is supplied from an electric power company to a HUB power supply device, and power is supplied from a HUB power supply device to a plurality of ONUs via power supply lines newly installed. It has been. Similarly, the communication multiplexing device (RT) in the CT-RT system is also arranged outdoors, and it is necessary to newly provide power supply equipment at the installation location.

一方、近年のパーソナルコンピュータ（ＰＣ）等を用いたＩＰ（インターネットプロトコル）通信の発展に伴い、IEEE802.3af 規定のＰｏＥ（Power over Ethernet(登録商標))やＵＳＢ（Universal Serial Bus) のように、端末や周辺機器への給電を通信用の伝送路を介して行う技術が開発されている。しかし、ＰｏＥの場合には、スイッチのように集線装置から端末や周辺装置への給電を行うシステムしかない（非特許文献３）。また、ＵＳＢの場合には、ＵＳＢバストポロジのホスト（通常はＰＣであり、ＵＳＢ配線内に１つしか存在しない）あるいは集線装置であるＨＵＢからの給電しか認められていない。したがって、ＰｏＥやＵＳＢの方式では、上記のように遠隔地や屋外に設置された通信多重装置（ＯＮＵ，ＲＴ）に対して、ユーザ側から給電することは想定されていなかった。

However, in the case of PoE, there is only a system that feeds power from the line concentrator to terminals and peripheral devices like a switch (Non-Patent Document 3). In the case of USB, only power supply from a USB bus topology host (usually a PC and only one in the USB wiring) or a HUB that is a line concentrator is permitted. Therefore, in the PoE and USB systems, it has not been assumed that power is supplied from the user side to the communication multiplexers (ONU, RT) installed at remote places or outdoors as described above.

従来の通信システムでは、通信局舎から遠隔に配置された通信多重装置（ＯＮＵ、ＲＴ）の給電をその設置場所で行う必要があったが、そのために新たに給電設備や給電線を設置する必要があり、コスト上昇の要因になっていた。 In the conventional communication system, it was necessary to supply power to the communication multiplexers (ONU, RT) remotely located from the communication station at the installation location. For this purpose, it is necessary to newly install power supply equipment and power supply lines. There was a cause of cost increase.

また、各端末側伝送線路からの給電量を個別にモニタすることにより、各端末側伝送線路に接続される各端末側通信装置（各ユーザ）からの給電量を検出することができる。これにより、給電に係る費用を各ユーザに対して返却するなどのサービスを実現することができる。 Moreover, the power supply amount from each terminal side communication apparatus (each user) connected to each terminal side transmission line can be detected by individually monitoring the power supply amount from each terminal side transmission line. As a result, it is possible to realize a service such as returning the cost related to power supply to each user.

The feature of this configuration example is that in the first configuration example shown in FIG. 3, a power supply amount measurement unit 38-1 that measures power, voltage, or current supplied from each of the terminal-side transmission lines 21-1 to 21 -N. 38-N. Other configurations are the same as those of the first configuration example shown in FIG.

本発明の通信多重装置３０では、ユーザ（通信サービス加入者）の宅内にそれぞれ設置される端末側通信装置１０−１〜１０−Ｎのうち、給電状態になった端末側通信装置から給電を受ける構成である。すなわち、ユーザ（通信サービス加入者）が通信多重装置３０の電力を負担するものであり、通信事業者が通信多重装置３０の電力を負担していた従来に比べてユーザ側の負担が増えることになる。そのため、通信多重装置３０の給電に係る費用を各ユーザに返却するサービスを想定する場合に、各ユーザの端末側通信装置１０−１〜１０−Ｎからの給電量を定量的に把握する必要がある。その理由は、各ユーザの端末側通信装置１０−１〜１０−Ｎと通信多重装置３０との距離が均一でなく、それぞれの給電量にばらつきが生じ、単純に通信多重装置３０の給電に係る費用をユーザ数で割ると不公平が生じるためである。 In the communication multiplexing device 30 according to the present invention, the terminal side communication devices 10-1 to 10-N installed in the user's (communication service subscriber) premises respectively receive power from the terminal side communication device in the power supply state. It is a configuration. That is, the user (communication service subscriber) bears the power of the communication multiplexer 30, and the burden on the user side is increased compared to the conventional case where the communication carrier bears the power of the communication multiplexer 30. Become. Therefore, when assuming the service which returns the expense which concerns on the electric power feeding of the communication multiplexing apparatus 30 to each user, it is necessary to grasp | ascertain quantitatively the electric power feeding amount from each terminal's terminal side communication apparatus 10-1 to 10-N. is there. The reason is that the distance between each user's terminal side communication device 10-1 to 10 -N and the communication multiplexing device 30 is not uniform, the power supply amount varies, and the communication multiplexing device 30 simply relates to the power supply. This is because unfairness occurs when the cost is divided by the number of users.

本構成例により、各ユーザごとに給電量を測定し、その情報を例えば共通回路部３４で収集して蓄積することにより、定期的に各ユーザからの給電量に見合う費用を各ユーザに返却するようなサービスも可能となる。 According to this configuration example, the power supply amount is measured for each user, and the information is collected and accumulated by, for example, the common circuit unit 34, so that the cost corresponding to the power supply amount from each user is periodically returned to each user. Such services are also possible.
