RCDD · Question #30
Which of the following is NOT true about consolidation points?
The correct answer is D. The maximum length of cable from the consolidation point (CP) to the outlet varies by media type. This question tests knowledge of consolidation point (CP) rules per ANSI/TIA-568, specifically identifying which statement about CP cable length limits is false.

Why each option
This question tests knowledge of consolidation point (CP) rules per ANSI/TIA-568, specifically identifying which statement about CP cable length limits is false.
CPs are passive interconnection points and the standard explicitly prohibits their use for direct connections to active equipment such as switches or wireless access points.
Allowing horizontal cables to be extended and rerouted into open-office or modular work area pathways is the primary design purpose of the consolidation point.
Each user's cabling must terminate on a dedicated, separate connector at the CP to maintain individual circuit integrity and support moves, adds, and changes without disrupting adjacent users.
Per ANSI/TIA-568, the maximum allowable cable length from the CP to the telecommunications outlet is not determined by media type; it is calculated by subtracting the floor distributor-to-CP cable length from the 90m total horizontal channel limit. The formula applies identically across supported horizontal media types, so the limit varies by installed FD-to-CP distance, not by media type.
