Summary

For the ODUkP to ODU[i]j adaptation sink function (ODUkP/ODU[i]j_A_Sk), the dMSIM defect will appear per tributary and not per higher order ODUk as it is checked per multiplexed tributary. Therefore, the following corrections are required:

–           to indicate that the defect is detected per active ODUj[/i] where a mismatch of detected and configured multiplex structure occurs;

–           and, as a consequence, the correlation (Alarm) is also to be raised per active ODUj[/i] instance.
