6.11 Voice and Data
Distribution System
The configuration and type of the voice and data cabling
distribution systems shall be developed at the earliest
stages of design, since the space requirements are so
significant and widespread. System requirements are user
generated and are generally translated into distribution
system requirements by a Registered Communications
Distribution Designer (RCDD).
Communications Raceways
Raised Access Floor. The standard option for delivering
communications services in Federal buildings is by laying
the cable in a tray for main runs and then branching
directly on the floor slab below the raised access flooring
system.
Cable Trays in Hung Ceilings. Since underfloor raceway
systems cannot accommodate the large turning radii
required by the CAT 6 and fiber optic cables, the primary
alternative to a raised floor system is a series of cable
trays installed above accessible hung ceilings. Cable trays
shall be grounded.
Alternate Raceways.
Exposed cable trays
Conduits in hung ceiling
