• Determining and making recommendations on whether and how NG9-1-1 can be extended to other N-1-1 services to ensure their reliability and cost-effective deployment.
• Identifying and recommending to the FCC a set of best practices to make communications networks, including broadband networks and VoIP systems, more secure, resilient, and defendable from Internet-based attacks.
• Developing recommendations for actions the FCC could consider to promote the development of a broadband-based, next generation alerting system that leverages advanced technologies and the Internet, including social media platforms, to distribute emergency alerts and warnings to the public.
• Identifying and recommending to the FCC actions to improve the functioning of the national security/emergency preparedness priority services programs: Government Emergency Telecommunications Service; Telecommunications Service Priority; and Wireless Priority Service.
• Making recommendations with respect to such additional topics as the FCC may specify.
