NANC Change Orders

The NANC Change Order section contains descriptions of the business functionality of the Number Portability Administration Center (NPAC) Service Management System (SMS) as defined by the Local Number Portability Administration Working Group (LNPA WG), which has a direct relationship to the processes and systems that each Service Provider uses to participate in LNP.

When a change in the NPAC software design is discussed at  the LNPA WG, the proposed change eventually is described in the form of a change order.  The change order document describes the business need for the software change and, at a high level, the software changes required to implement the proposal.  As discussions progress, the technical portion of the change order is expanded to document both new software requirements and changes to existing software requirements that would result if the Change Order were implemented.  (Operational impacts of a change order are described in "Method & Procedures" documents issued before the change order is implemented.)  In this section of the NPAC.com web site, all change orders ever considered are listed.  The final change order document and the LNPA WG discussion notes, the change order's status, and the identity of the software release in which the change order was implemented are provided here.

 The status of a change order may be either Closed, Open, Implemented, or Requested.  These terms are defined as follows:

  • Closed – The change order was considered and rejected.
  • Open – The change order has been considered and there may be further discussion.
  • Implemented – The change order was adopted and has been implemented in the NPAC system.
  • Requested – The LNPA WG has asked the NAPM LLC to arrange for the change order's implementation, but the change order is not yet implemented.
