A database managed by Intrado or other 9‐1‐1 hosts. The ALI database is accessed by the PSAP when a 9‐1‐1 call comes in; it is accessed by the telco in an SR/ALI routing environment to route a 9‐1‐1 call to the PSAP. The TN, address, and name associated with the phone from which the 9‐1‐1 call is placed are furnished to the PSAP through the ALI database.
