INTRODUCTION

This document is intended as an aid in reporting and resolving troubles involving Local Number Portability. This document is not meant to replace or supercede other NIIF agreements and procedures.

Due to the complexity of LNP, problem resolution can involve ILECs, CLECs, IXCs and Wireless Carriers, as well as 3^rd party Database and Service Bureau Providers. This service relies almost exclusively on network element provisioning being performed/timed correctly throughout all networks. Trouble reporting should be handled following processes and procedures developed by each entity. Troubles should not be reported to another entity's field personnel directly. If order/repair processes are not followed, it is difficult to measure performance, trouble types, volumes or to initiate possible required billing.

For the purposes of this document, SP-X is the "ported from/donor" network, SP-Y is the "ported to/recipient" network, and SP-Z is neither the "ported from" nor the "ported to" network, but may be another service provider(s) involved in the trouble report. SP-Z may be a long distance carrier network, another local service provider's network or access tandem service provider network. There are procedures in the NIIF Reference Document for trouble reporting in a multiple service provider environment.
