[LS-753] Number Change

Tue, 31 Mar 2026 14:20:45 +0300

In the Number Change Scenario where an existing subscriber's number (the "old subscriber") is replaced by a new subscriber's number (the "new subscriber"), the Network Element Platform (NEP) is incorrectly using the Old Subscriber Number (SN) when sending a Modify Request to iLink.
The correct behavior should be for the NEP to send the latest, newly associated SN that has been moved from the old subscriber to the new subscriber.
Example
• Existing Association: SN 48575443FE96CAAD is associated with subscriber 24664885.
• Number Change: Subscriber 24809480 is changed to 24664885.
• SN Movement (Correct): SN 48575443EF0952B3 (previously on 24809480) is moved to 24664885.
• Current NEP Error: NEP sends the old SN (48575443FE96CAAD) to iLink.
• Required NEP Action: NEP must send the newly added SN (48575443EF0952B3) to iLink.

Conclusion & Follow-Up

The core problem is that the NEP is not selecting the latest and most relevant SN after a number change. Please review this required change.
