摘要：
In a case where a wavelength to be assigned to a subscriber-side device, to which a downstream wavelength has been assigned, is to be changed from the currently used (Source) downstream wavelength to a different changeover target (Target) downstream wavelength, a downstream wavelength changeover instruction message that indicates the change target wavelength is generated. In a case where a wavelength to be assigned to the subscriber-side device, to which an upstream wavelength has been assigned, is to be changed from the currently used (Source) upstream wavelength to a different changeover target (Target) upstream wavelength, an upstream wavelength changeover instruction message that indicates the change target wavelength is generated. The downstream wavelength changeover instruction message and the upstream wavelength changeover instruction message are respectively independently generated, and only the wavelength for which the wavelength changeover instruction message was generated is changed.
摘要（中）：
在要分配给已经分配了下行波长的用户侧设备的波长将从当前使用的（源）下行波长改变为不同的转换目标（目标）下行波长的情况下， 产生指示改变目标波长的下游波长改变指示消息。 在将分配给已经分配了上行波长的用户侧设备的波长从当前使用的（源）上行波长改变为不同的转换目标（目标）上行波长的情况下， 产生指示改变目标波长的上游波长改变指示消息。 下行波长切换指示消息和上行波长切换指示消息分别独立产生，只有产生波长切换指示消息的波长发生变化。
