Figure 6-6. Operation Status
The transition filters convert conditions to events.
The transition filters include an NTRansition filter and a PTRansition filter. The settings and operations of
these filters are described below.
•
When the NTR filter is set to 1, OPER is set to 1 when OPCR changes from 1 to 0.
•
When the PTR filter is set to 1, OPER is set to 1 when OPCR changes from 0 to 1.
•
When the NTR and PTR filters are both set to 1, OPER is set to 1 when OPCR changes.
•
When the NTR and PTR filters are both set to 0, changes in OPCR are not propagated to OPER.
