Title 47 › Chapter 5— WIRE OR RADIO COMMUNICATION › Subchapter VI— MISCELLANEOUS PROVISIONS › § 623
Require companies that make, sell, import, lease, install, manage, or operate multi-line telephone systems to let anyone at any phone station call 9-1-1 directly. Users must be able to dial 9-1-1 without adding any extra digit, code, prefix, or postfix — including trunk-access codes like the digit "9" — even if those codes are needed for other calls. New systems offered for use must come pre-set this way, and installers or operators must configure systems the same. If a system can be set to send a notification without changing its hardware or software, the installer or operator must turn that on so a central location at the facility or another person or organization gets notified. State and local emergency communications authorities keep their powers unless those powers conflict with this chapter. Enforcement is under subchapter V, with section 501 applying only for fines. The term "multi-line telephone system" is defined in section 1471 of this title.
