PURPOSE AND SCOPE This document contains the guidelines and procedures for the assignment and use of pANIs Used To Route Emergency Calls@ such as E9-1-1 calls or other types of emergency calls that need to become native E9-1-1 calls throughout the North American E9-1-1 systems (USA Canada). The pANIs used in this capacity perform the same function as pANIs used today@ but they afford the industry advantages over the ranges typically used for pANIs today. Today these pANI numbers are a 10-digit number that typically have been obtained from the assigned number ranges of the carrier needing them@ for example@ a wireless carrier would use numbers from their own valid NANP number ranges as their pANIs@ or from an E911SSP in some areas of the USA. The pANI is used by emergency call handling networks to perform call routing and data retrieval procedures. The use of a regular domestic number obtained from the assigned number range often results in erroneous calls to Public Safety Answering Points (PSAP) because they are typically dialable numbers@ that can be mis-dialed. The pANIs administered by the RNA will initially consist of two ranges within each NPA (NPA-211-xxxx or NPA-511-xxxx). These ranges have been set aside by INC for this purpose at the request of ESIF@ and INC deferred responsibility for identifying a RNA. These ranges are expected to be controlled by all originating switch operators so as to render them routable but non-dialable. Every pANI should be associated with a single call delivery technology (e.g.@ wireless@ VoIP). In other words@ a given pANI should not be used for wireless on one call and subsequently used for a VoIP call. The Eligible User is responsible for tracking this delivery technology per pANI and must be able to communicate that the specific usage to the RNA as needed. By using these otherwise INC restricted use number ranges the industry also frees up the equivalent quantity of otherwise valid NANP numbers for use in day-to-day telephone number assignment processes. Until now there has been no centralized administration for pANIs and their formats. The establishment of the RNA role by ATIS/ESIF will begin to address this problem by administering pANIs used for routing emergency calls. A brief description of the role of the RNA follows: The RNA manages and coordinates the assignment of the pANIs Used for Routing Emergency Calls@ under the oversight of the chartering entity (i.e.@ FCC@ ATIS/ESIF@ etc.). In areas where E911SSPs had performed this function prior to the establishment of the RNA@ that role is expected to continue at the discretion of those entities. In such a case they would be known as the sub-RNA for the area(s) where they act as the E911SSP. ESIF foresees that sub-RNAs should only exist during the transition period until a single RNA is performing the roles and responsibilities defined in this document. These guidelines were developed by the consensus of representatives in ESIF. Members from the wireline and wireless sectors and from the PSAP sector are represented with the ESIF. These guidelines apply to all Eligible Users as defined herein. These guidelines do not supersede the regulations@ procedures@ or requirements of any appropriate national or international legal or regulatory authority. Any numbers that fall within the ranges assigned by INC for this purpose that are already in use for said purpose will remain in use.
