Planning and Design

1.2.1 Reference: UFC 3-580-01, Par. 2-1

Design of interior and exterior telecommunications infrastructure must meet the needs of the activity and supporting facilities. Architects & Engineers (A&E) contractor generated final drawings and specifications for Design-Bid-Build and Design-Build projects must be stamped by a BICSI Registered Communications Distribution Designer (RCDD).

1.2.2 The German equivalent to the BICSI RCDD is “VdS anerkannter Sachkundiger für Gebäude- Infrastruktur-Verkabelung”. The consulted A&E contractor shall be a certified Communications Distribution Designer IAW VdS regulation 3117, with min. 3 years of experience in planning and installing cyber infrastructure and systems, specifically for the DoD Armed Forces in Europe.

1.2.3 Design and construction may be concurrent efforts in Design-Build projects, and multiple phases of construction may be approved. Therefore, the final documents for each construction phase must be stamped by the RCDD.

1.2.4 Design and install a complete standard based, flexible telecommunications design including telecommunications spaces, pathways, receptacles, connectors, cabling, grounding, bonding, and static protection. This document follows the standards and guidelines listed in APENDIX A.

Primary Cabling

2.2.1 The primary cabling is running from the campus distributor (CD) to the single building or multiple buildings of the same location, or it connects buildings amongst each other.

Secondary Cabling

2.3.1 The lines between separated data distributors within a building, the building distributors (BD), are referred to as secondary cabling.

Building Backbone Cabling

2.4.1 On every floor of a building, at least one floor distributor (FD) should be installed. For in such a case vertical floors are connected, the terminology building backbone cabling is used.

Tertiary Cabling

2.5.1 Attached to that, we find the tertiary cabling. It describes the data cables leading to the data/voice outlets (DO) or to consolidation points anterior to it. This is referred to as horizontal cabling.
