The FCC has released a draft of a Notice of Proposed Rulemaking that seeks comment on a rule prohibiting the use of universal service fund support to purchase equipment or services from any communications equipment or service providers identified as posing a national security risk to U.S. communications networks or the communications supply chain. The proposed rule would apply prospectively, and extend to upgrades of existing equipment or services. Comment deadlines will be announced after the NPRM is formally adopted.
