Maintenance Messages without Unlocking the DPC

We have observed that ISUP Maintenance messages over a link flow without unlocking the DPC. Whereas, Maintenance message Inhibit & Unhibit require DPC to be unlocked. Also, when DPC is locked a COO is acknowledged with ECA. whereas, when DPC is unlocked COO is acknowledged with COA. why so??
