| description | PROBLEM TO BE SOLVED: To shorten a time for a switching process of a communication path for a communication signal.SOLUTION: An OLT 1 includes: an active PON interface unit 7 for outputting a communication signal; a standby PON interface unit 9; and a control unit 6 for transmitting a switching control signal. The active PON interface unit 7 includes: a memory 14; a CPU 13 for issuing instructions on data transfer according to the switching control signal; and a communication control unit 18 composed of at least one piece of hardware different from the CPU 13. When a communication path is switched, the communication control unit 18 reads out data stored in the memory 14 according to the instructions from the CPU 13, and transfers it toward the standby PON interface unit 9.SELECTED DRAWING: Figure 3
【課題】通信信号の通信経路の切り替え処理の時間を短縮する。【解決手段】ＯＬＴ１は、通信信号を出力する現用系ＰＯＮインタフェース部７と、予備系ＰＯＮインタフェース９部と、切替制御信号を送信する制御部６とを備える。現用系ＰＯＮインタフェース部７は、メモリ１４と、切替制御信号に従ってデータ転送の指示を出すＣＰＵ１３と、ＣＰＵ１３とは異なる少なくとも１つのハードウェアで構成された通信制御部１８とを有し、通信経路の切り替えのとき、通信制御部１８は、ＣＰＵ１３からの指示に従ってメモリ１４に記憶されたデータを読み出し、予備系ＰＯＮインタフェース部９に向けて転送する。【選択図】図３ |
