本発明の実施形態の説明に先立って、本発明の特徴についてその概要をまず説明する。本発明は、通信システムを構成する各通信装置に対して給電する電源を選択する仕組みに関するものである。通信システムは、複数の通信装置、例えば屋内側通信装置(IDU:In Door Unit)および屋外側通信装置(ODU:Out Door Unit)で構成される。各通信装置は、内蔵または外部接続の電源で構成される第1電源に接続される。さらに、各通信装置は、その第1電源からの電力を動作用電源として取り込むための電源入力機構と、互いを接続した通信線上の信号に重畳させて該第1電源からの電力を相手側の通信装置に対して第2電源として送電する電力送電機構と、該通信線上の信号に重畳されて相手側の通信装置から第2電源として送電されてきた電力を動作用電源として取り込む電力抽出機構とを備える。さらに、屋内側通信装置(IDU)と屋外側通信装置(ODU)との間の通信線は、いずれの方向にも、信号と電力とを重畳させて送ることを可能にし、屋内側通信装置(IDU)と屋外側通信装置(ODU)との間の通信線に電源を重畳する際には、屋内側通信装置(IDU)から屋外側通信装置(ODU)へ、屋外側通信装置(ODU)から屋内側通信装置(IDU)への双方向の送電を可能にする仕組みを備えている。
