NENA Technical Standards


NENA Standards are developed by the NENA Technical Committees: Network, Data, PSAP/CPE and ALEC/PS. Once approved by the NENA Executive Board, these standards help ensure consistency in the 9-1-1 industry. Telcos, vendors and users all benefit from widespread adoption of the standards.
