Description
The implementation of Enhanced F&ES telecommunications services requires that the emergency services answering point or call center be able to automatically locate the calling party in the event they are unable provide their location themselves. This is a two part process. First the telephone system must be able to provide the answering station with the telephone number from which the emergency call originated. This is Automatic Number Identification (ANI) information. The second step in the process is that this phone number must be correlated to a physical address or location. This is called Automatic Location Identification (ALI) information. ANI information comes from the telephone system controller. ALI information may come from an external database that associates the ANI information to the ALI information or the telephone system controller may maintain the ALI database internally. If the ALI database is internal to the telephone system controller, emergency services answering point or call center only needs to receive ALI information providing it contains the originating telephone number.
