So in a ¾ conduit the minimum bend radius would be 4.5 4.06 Pull boxes shall be used when the length of a run is over 100 feet or if there are bends totaling more than 180 o or if there is a reverse bend in the run. Pull boxes shall be positioned so that the conduit ends align with each other, and shall be so located where they will be readily accessible and indicated on the as-builts. 4.07 Conduit runs shall be clearly labeled at both ends. In the communications room the conduit shall be labeled with the destination work area room number and conduit number. At the work area outlet the conduit shall be labeled in the outlet box indicating the communications room number where the conduit ends. 4.08 Cabling installed in ceiling space is preferred to be in cable tray. Instances where cable tray is not available, cabling must be properly supported and may not lay on the ceiling tiles. When supporting communications cabling all NEC codes governing how cabling is to be supported must be followed. Cable support attachments must be no more than three feet apart. 2 P a g e
4.09 Firestopping shall comply with applicable codes. Information on firestopping can be obtained from the EIA/TIA or BICSI standards manual. 5. HORIZONTAL CABLING is that portion of the cabling system which extends from the communications work area outlet to the nearest communications room. 5.01 Cable distances shall follow the EIA/TIA and BICSI standards of 295 feet for installation of Category 6 or 6a cabling. 5.02 Approved cables to be used in the horizontal cabling system are: A.

9. Labeling horizontal cabling cables terminating in the communications room shall have the room number and outlet number from where it came. At the outlet end, the outlet itself shall be labeled with the circuit number that the cable has been assigned. The contractor shall request the Labeling Layout from UND Telecommunication prior to the need of this information. Room numbers shall be UND numbers and not the A/E plan drawing numbers. 9.01 All horizontal cabling faceplates and patchpanels shall be labeled with the room number, the alpha indicator, if used, the outlet number, and the jack position number. An example of a data drop in room 216, where the outlet is the third outlet in the room, and the jack is inserted in position 1 on the faceplate, the label will be 216R3-1. If this were for room 216A instead of 216 the label would read as 216AR3-1. The jack inserted in position two would be labeled, 216AR3-2. A. The outlet faceplate in the room or office would only be labeled with the room number, alpha character, and the outlet number. The faceplates are prestamped with the jack position number. B. The labeling format will be the same for phone or for data. The outlet and termination block will be labeled the same for either type of cable. C. Backbone cables would be labeled as cable Number and Count. Example; 1,1101-1200 is Cable Number 1 and Cable Count 1101 through 1200. This numbering system will be determined by the Telecommunications. 5 P a g e
