Replacing POTS Lines in Wisconsin

Elevator Emergency Phone

ASME A17.1 requires a live-attendant emergency phone in every cab. When copper retires, that phone goes silent.

See options →

Fire Alarm Panel

NFPA 72-compliant fire alarm monitoring depends on a working phone line. Copper retirement puts your panel offline.

See options →

Fax Machine

Healthcare and legal faxing depends on analog lines. Digital fax adapters maintain compliance after copper retires.

See options →

Security System

Burglar alarms, gate intercoms, and access control systems that dial out over POTS lose their connection when copper retires.
