AT&T copper retirement in Ohio: what building owners need to know
Ohio is a major AT&T legacy market — the company inherited Ohio Bell's entire copper network. Columbus, Cleveland, Cincinnati, Dayton, Akron, and Toledo are all AT&T territory, and the copper retirement is hitting the state hard. Commercial buildings across Ohio are receiving disconnect notices with just 90 days to find a replacement.

June 2026 — Wire center shutdowns begin

What's at risk
- Fire alarm panel — DACT can't reach monitoring station. Fails NFPA 72 inspection. Ohio State Fire Marshal can issue violation.
- Elevator emergency phones — every cab goes dead. Fails state elevator inspection.
- Security alarm — building goes unmonitored. Insurance risk.
- Building entry and gate — intercoms and callboxes go silent.
- Area of refuge phones — ADA-required stairwell phones fail.
- Fax and POS — medical, legal, and retail connectivity lost.
A typical Columbus or Cleveland building with 8 POTS lines paying $1,200–$3,000/month on copper drops to $240–$480/month on cellular. Annual savings: $8,600–$30,000+.
