Class 1 administration addresses the more limited scope of a single telecommunications room and its associated horizontal cabling only.

Class 2 administration is defined in ANSI/TIA-606-B as providing administration for a single building or a tenant served by single or multiple entrance facilities, encompassing horizontal cabling, backbone cabling, pathways, and associated spaces within that scope. This class expands beyond a single telecommunications room to address all infrastructure elements serving the building or tenant, making it the correct fit for the described scenario.

Class 3 administration covers multiple buildings on a campus and their interconnecting backbone infrastructure, which is broader than a single building.

Class 4 administration is intended for enterprise-wide or multi-site administration spanning multiple campuses or geographic locations.
