California urges court, FCC to rule AT&T must continue basic phone service

Summary

The California Public Utilities Commission has asked a US court and the FCC to reject AT&T's request to stop offering traditional copper-wire phone service to new customers, arguing the carrier cannot abandon its carrier-of-last-resort obligations even as AT&T contends it spends $1 billion annually maintaining a century-old network serving just 3% of households across 360 California wire centers.

Market Impact

The dispute crystallizes the regulatory tension between legacy universal-service mandates and carriers' economic incentive to retire costly copper infrastructure. AT&T seeks FCC permission to discontinue legacy copper service affecting approximately 184,000 residential and 15,000 business customers by June 2027, and a separate FCC petition to declare that federal standards preempt California's technology-neutral basic-service rules. The CPUC's technology-neutral framework—requiring 'basic service' regardless of whether delivered via copper, wireless, or VoIP—sets up a precedent-setting test of state versus federal authority over network modernization that could shape copper retirement timelines for incumbent carriers nationwide.

Why It Matters

The California-AT&T copper service dispute is a precedent-setting test of state carrier-of-last-resort obligations against federal preemption, with implications for how quickly incumbent telecom carriers can retire costly legacy infrastructure nationwide.

Key Points

• The California Public Utilities Commission asked a US court and the FCC to reject AT&T's request to stop offering traditional copper-wire phone service to new customers, citing carrier-of-last-resort obligations
• AT&T says it spends $1 billion annually maintaining a century-old network now serving just 3% of households in its California territory
• AT&T seeks to discontinue legacy copper service across portions of 360 California wire centers effective June 2027, affecting approximately 184,000 residential and 15,000 business customers
• The CPUC argues its rules are technology-neutral—applying to copper, wireless, or VoIP equally—while AT&T separately petitioned the FCC to declare federal standards preempt California's requirements
