The NRUF only pertains to BLOCKS assigned to your OCN. Returning blocks 
in NPAC only pertains to TNs you've ported to your LRN that you no 
longer use. You mixed up the third component of reporting disconnects. 
That's done in the RND database and those should be reported monthly.

All 3 are totally separate from each other and used for different 

- NRUF it to report number utilization and forecasting of NXX blocks
- NPAC is the database used for porting telephone numbers
-RND is used for reporting numbers that are disconnected. In my opinion, 
if the numbering administration was smart they would track the ported 
TNs no longer in use in the RND database so the original carrier can 
reclaim the numbers that are no longer being used because a lot of TNs 
get lost when the customer disconnects but they are not returned to the 
original carrier.
