§ 9.3 Definitions.

ANI. Automatic Number Identification, as such term is defined in § 20.3 of this chapter.

Appropriate local emergency authority. An emergency answering point that has not been officially designated as a Public Safety Answering Point (PSAP), but has the capability of receiving 911 calls and either dispatching emergency services personnel or, if necessary, relaying the call to another emergency service provider. An appropriate local emergency authority may include, but is not limited to, an existing local law enforcement authority, such as the police, county sheriff, local emergency medical services provider, or fire department.

Automatic Location Information (ALI). Information transmitted while providing E911 service that permits emergency service providers to identify the geographic location of the calling party.

CMRS. Commercial Mobile Radio Service, as defined in § 20.3 of this chapter.

Interconnected VoIP service. An interconnected Voice over Internet protocol (VoIP) service is a service that:

(1) Enables real-time, two-way voice communications;

(2) Requires a broadband connection from the user's location;

(3) Requires Internet protocol-compatible customer premises equipment (CPE); and

(4) Permits users generally to receive calls that originate on the public switched telephone network and to terminate calls to the public switched telephone network.

PSAP. Public Safety Answering Point, as such term is defined in § 20.3 of this chapter.

Pseudo Automatic Number Identification (Pseudo-ANI). A number, consisting of the same number of digits as ANI, that is not a North American Numbering Plan telephone directory number and may be used in place of an ANI to convey special meaning. The special meaning assigned to the pseudo-ANI is determined by agreements, as necessary, between the system originating the call, intermediate systems handling and routing the call, and the destination system.

Registered Location. The most recent information obtained by an interconnected VoIP service provider that identifies the physical location of an end user.

Statewide default answering point. An emergency answering point designated by the State to receive 911 calls for either the entire State or those portions of the State not otherwise served by a local PSAP.

(2) Includes a selective router; and

(3) Is utilized to route emergency calls and related information to PSAPs, designated statewide default answering points, appropriate local emergency authorities or other emergency answering points.
