7. NOTES
- Assumption - interim period will be limited to non-contaminated blocks
- Interim Pooling Administrator will be in `place no later than
- Pooling Administrator must be in place to support Pooling
- NPAC manual conversion requirements needed (M&P) to update NPAC SMS and all local LSMSs
- During interim manual pooling process - To avoid numerous notifications - Inter-SP ports should be coordinated
-Assumption - 1K Block will be pooled to one end Office (EO) switch (NPAC requirements allow more flexibility
- Snap Back to the Block Holder would be managed by existing NPAC functionality. Operational Flows are identical
to “Port To Original” porting process flow.
- Snap Back in manual interim mode will have to be managed thru M&P
