Claims (1)
間で双方向データ通信を行う場合に、各家庭端末
に設置される屋内分配器であつて、各家庭端末内
の一分配端末からセンター向けの上り方向のデー
タ通信を行う際に、各家庭端末内の他の分配端末
から発生する雑音がセンターに流入することを阻
止するための高域波器を分配器のセンター側に
付加してなるフイルタ付き屋内分配器。 When two-way data communication is performed between the center and each home terminal through a CATV transmission line, an indoor distributor installed in each home terminal transmits data in the upstream direction from one distribution terminal in each home terminal to the center. An indoor distributor with a filter that includes a high frequency filter added to the center side of the distributor to prevent noise generated from other distribution terminals in each household terminal from flowing into the center during communication. .
