Title 47 Part 68.213
(b) Wiring authorized. Unprotected premises wiring may be used to connect units of terminal equipment or protective circuitry to one another, and to carrier-installed facilities if installed in accordance with these rules. The provider of wire-line telecommunications is not responsible, ... portion removed ..., for installation and maintenance of wiring on the subscriber's side of the demarcation point, including any wire or jacks that may have been installed by the carrier. The subscriber and/or premises owner may install wiring on the subscriber's side of the demarcation point, and may remove, reconfigure, and rearrange wiring on that side of the demarcation point including wiring and wiring that may have been installed by the carrier. The customer or premises owner may not access carrier wiring and facilities on the carrier's side of the demarcation point. Customers may not access the protector installed by the provider of wireline telecommunications. All plugs and jacks used in connection with inside wiring shall conform to the published technical criteria of the Administrative Council for Terminal Attachments. ... portion removed ... The customer or premises owner may not access carrier wiring and facilities on the carrier's side of the demarcation point. Customers may not access the protector installed by the provider of wireline telecommunications. All plugs and jacks used in connection with inside wiring shall conform to the published technical criteria of the Administrative Council for Terminal Attachments.
(c) Material requirements. (1) For new installations and modifications to existing installations, copper conductors shall be, at a minimum, solid, 24 gauge or larger, twisted pairs that comply with the electrical specifications for Category 3, as defined in the ANSI EIA/TIA Building Wiring Standards.
(2) Conductors shall have insulation with a 1500 Volt rms minimum breakdown rating. This rating shall be established by covering the jacket or sheath with at least 15 cm (6 inches) (measured linearly on the cable) of conductive foil, and establishing a potential difference between the foil and all of the individual conductors connected together, such potential difference gradually increased over a 30 second time period to 1500 Volts rms, 60 Hertz, then applied continuously for one minute. At no time during this 90 second time interval shall the current between these points exceed 10 milliamperes peak.
(3) All wire and connectors meeting the requirements set forth in paragraphs (c)(1) and (c)(2) shall be marked, in a manner visible to the consumer, with the symbol “CAT 3” or a symbol consisting of a “C” with a “3” contained within the “C” character, at intervals not to exceed one foot (12 inches) along the length of the wire.
