Whether optical-layer ASON services are rerouted after an OBU board is removed and re-inserted

Question:
If frontline engineers remove an OBU board from the OSN 6800 V100R007C02SPC200 in the optical-layer ASON network, and the corresponding FIU board does not report any alarms, will ASON services on the FIU board be rerouted?

The OMS_TEL_DOWN alarm is generated on the TE link xxx as follows:
OMS_TEL_DOWN CR start 2013-11-18 14:29:30+05:30 None NSA TEL Node=172.16.0.113,TE LinkID=0x8;,Sub-shelf=0,Board=2,Port=1,Error=0x2;

Answer:
In versions earlier than V100R007C00, after an OBU board is removed, ASON services on the corresponding FIU board are not rerouted. Since V100R007C00, the offline alarms of an OBU board are transferred to the corresponding FIU board. As a result, ASON services on the FIU board are rerouted. In conclusion, after an OBU board is removed from OSN 6800 V100R007C02SPC200, ASON services are rerouted.

Suggestion and conclusion:
By default, in versions earlier than V100R007C00, optical-layer ASON services are rerouted on the condition that the FIU board reports the MUT_LOS or BD_STATUS alarm. Since V100R007C00, optical-layer ASON services are also rerouted on the condition that boards on the line dimension report the BD_STATUS alarm. These boards can be OA boards, and multiplexer/demultiplexer boards.
