Supplemental Guidance
Organizations consider the potential mission or business impact in situations where telecommunications service providers are servicing other organizations with similar priority of service provisions. Telecommunications Service Priority (TSP) is a Federal Communications Commission (FCC) program that directs telecommunications service providers (e.g., wireline and wireless phone companies) to give preferential treatment to users enrolled in the program when they need to add new lines or have their lines restored following a disruption of service, regardless of the cause. The FCC sets the rules and policies for the TSP program, and the Department of Homeland Security manages the TSP program. The TSP program is always in effect and not contingent on a major disaster or attack taking place. Federal sponsorship is required to enroll in the TSP program.
Practitioner Notes
This enhancement requires priority of service provisions in your telecommunications contracts — during a widespread outage, your organization should get prioritized restoration.
Example 1: Enroll in the Telecommunications Service Priority (TSP) program to get priority restoration of your critical telecommunications circuits during a national emergency.
Example 2: Negotiate SLA terms with your ISP that include priority restoration and dedicated support contacts during outages affecting multiple customers.
