Our engineer find that in 155/622H equipment, some ports of PD2T board can not set the alarm reversion successful, the error code is 16387.
But after set it as "Manual Mode", the alarm reversion is successful.
error code is 16387
When ports have no "LOS" alarm, pls set as "Manual reversion " mode.
1. The error code 16387 exactly means that there is no "LOS" alarm found when the alarm set into Auto reversion mode,.
2. In 155/622H and 155/622 product, only ports (including both LU and TU) has "LOS" alarm can support the Auto alarm reversion function.
3. IF you want to set alarm reversion in the ports which does not have "LOS" alarm, pls set it as "Manual Reversion" mode.
When this case happens, first pls set the alarm reversion mode to "Manual reversion", then set the alarm reversion of not.
