Description / Abstract:

Scope & Purpose

The Telecommunications Service Priority (TSP) codes for national security and emergency preparedness (NS/EP) enables NS/EP organizations to receive priority treatment for vital voice and data circuits or other telecommunications services. These codes, when provided, require and authorize service providers to provision and restore certain services, which have been designated most critical to NS/EP. Services being requested for provisioning or restoration shall have full attention and priority over non-TSP service requests.

The TSP System and procedures apply to give priority treatment to the following telecommunication services:

  • Common carrier services which are interstate and foreign telecommunications services; 

  • Common carrier services which are intrastate telecommunications services inseparable from interstate or foreign telecommunications services, and intrastate telecommunications services to which TSP priority levels are assigned; and

  • Services, which are provided by government and/or non-common carriers and are interconnected to common carrier services, assigned TSP priority levels.

This standard establishes the specifications, characteristics, and values of the NS/EPTelecommunications Service Priority code used by the NS/EP TSP and telecommunication service vendors providing NS/EP services.
