Summary: | To make it possible to easily introduce new F/W.SOLUTION: An OLT 120 includes: a first lower I/F board 140#1 in which update is performed with first F/W; a second lower I/F board 140#2 in which update is performed with second F/W that is newer than the first F/W; a receiving unit that receives a F/W combination module that includes a unique name of the first F/W but does not include a unique name of the second F/W in a common file header, which is a header of a common file area including the first F/W and the second F/W; a memory 132 that stores the F/W combination module; a file dividing unit 133 that divides the first F/W and the second F/W from the F/W combination module when an update instruction is received after the reception of the F/W combination module; and a file transfer unit 136 that transfers the first F/W to the first lower I/F board 140#1 and transfers the second F/W to the second lower I/F board 140#2.SELECTED DRAWING: Figure 2
【課題】新規なF/Wを、容易に導入できるようにすること。【解決手段】OLT120は、第1のF/Wで更新を行う第1の下位I/F基板140#1と、第1のF/Wよりも新しい第2のF/Wで更新を行う第2の下位I/F基板140#2と、第1のF/W及び第2のF/Wを含む共通ファイル領域のヘッダである共通ファイルヘッダに、第1のF/Wの固有名称を含むが、第2のF/Wの固有名称を含まないF/W結合モジュールを受信する受信部と、F/W結合モジュールを記憶するメモリ132と、F/W結合モジュールの受信後に更新指示が受信された場合に、F/W結合モジュールから、第1のF/W及び第2のF/Wを分割するファイル分割部133と、第1のF/Wを第1の下位I/F基板140#1に転送し、第2のF/Wを第2の下位I/F基板140#2に転送するファイル転送部136とを備える。【選択図】図2 |
