(1) For new and existing single unit installations, the demarcation point shall be a point at (or about) twelve inches outside of where the cable wire enters the subscriber's premises.
(2) For new and existing multiple dwelling unit installations with non-loop-through wiring configurations, the demarcation point shall be a point at (or about) twelve inches outside of where the cable wire enters the subscriber's dwelling unit, or, where the wire is physically inaccessible at such point, the closest practicable point thereto that does not require access to the individual subscriber's dwelling unit.
(3) For new and existing multiple dwelling unit installations with loop-through wiring configurations, the demarcation points shall be at (or about) twelve inches outside of where the cable wire enters or exits the first and last individual dwelling units on the loop, or, where the wire is physically inaccessible at such point(s), the closest practicable point thereto that does not require access to an individual subscriber's dwelling unit.
(4) As used in this paragraph (mm)(3), the term “physically inaccessible” describes a location that:
(i) Would require significant modification of, or significant damage to, preexisting structural elements, and
(ii) Would add significantly to the physical difficulty and/or cost of accessing the subscriber's home wiring.
