UC Santa Cruz – Division 27 – Communications: Design Guide27 00 00 - CommunicationsIntroductionThis document's objective is to provide Architects and other designers with a design-requirements andguidelines document that will help them plan the telecommunications facilities for the UCSC campus. TheScope of Work includes the telecommunication inside plant (ISP) and outside plant (OSP) cabling andsupport facilities required by new buildings or additions and/or upgrading of existing buildings andfacilities. The document is a design guide and is not a project specifications document.Telecommunications Spaces (TS)1. Telecommunications Spaces (TS): The term TS refers to space allocated within a building toprovide a secure operating environment for telecommunications cabling and termination facilitiesand/or network equipment. TS’s shall be designed and provisioned per ANSI/TIA-569Telecommunications Pathways and Spaces and per the BICSI Telecommunications DistributionMethods Manual (TDMM), most recent edition. Depending on the building size, design, andnetwork requirements, one or more of the functions of a TS may be combined into one space.The primary functions housed in TS’s are:a. Telecommunications Rooms (TR)b. Entrance Facility (EF)c. Equipment Room (ER)d. Area Distribution Frame (ADF)e. Building Distribution Frame (BDF)f. Intermediate Distribution Frame (IDF)Types of ISP TS/TR Facilities1. Typesa. Entrance Facility (EF): Is a room that houses the termination and grounding point of OSPnetwork service cables that enter or exit a building. It enables the joining of intra-buildingand inter-building backbone cabling. The EF is generally co-located in a BDF or ADFrather than being a separate room.b. Equipment Rooms (ER): Is a room that houses telecommunications equipment.c. Area Distribution Frame (ADF): Is a multiple-building serving facility. The ADF is the roomwithin a building for telecommunications equipment that meets the voice, data, video,radio, and wireless needs of its building and also serves other buildings in a designatedarea (zone) on the UCSC campus. It generally acts as an EF and BDF but can also act asan IDF serving the floor it occupies. ADFs are generally placed on the lowest floor of abuilding to allow the entry of OSP cables without transition splicing and for grounding ofDIVISION 27 – COMMUNICATIONS: DESIGN GUIDEFebruary 2018Page 3 of 54

UC Santa Cruz – Division 27 – Communications: Design Guidecables.An ADF provides a controlled environment to house telecommunications equipment,termination hardware, splice closures, Main Telecommunications Grounding Busbar(MTGB) grounding and bonding facilities, and protection apparatus where applicable.Equipment in the ADF includes the Campus PBX telephone systems (LIMs) or MX1equipment; local area and core network switches; video distribution equipment; wirelessnetwork equipment; Land Mobile Radios (LMR) and Public Safety Networks (PSN) forfirefighters, police and first responders including the campus 800 MHz radios and offcampus police and fire frequencies used for in-building radio equipment (also known asDistributed Antenna System or DAS as defined in CBC Article 915 and CFC Article 510);in-building cellular systems; and large uninterruptible power sources that are sized tooperate the ADF cooing and electronics for up to 8 hours.ADFs are distinct from other TRs due to the nature and/or complexity of the equipmentthey contain. They are distribution points for the campus fiber and copper OSP cable plant.d. Building Distribution Frame (BDF): Is a building-serving facility. The BDF enablesconnection of OSP services (telecommunications) to the building and then distributes thoseservices throughout the building to IDFs using riser cables.e. Intermediate Distribution Frames (IDF): Are considered to be floor servicing facilities asopposed to building service facilities. The IDF provides a connection point between risercable from the BDF and the end user Work Area Outlet (WAO) horizontal cabling. All newmulti-story buildings shall have at minimum one (1) IDF on each floor of the building. Morethan one (1) IDF per floor may be required in larger buildings where cable lengths of 295 ft.per ANSI/TIA Standards would otherwise be exceeded. In remodels of existing buildings ofor less than 5000 GSF it is permissible for an IDF to service an adjacent floor. Thisexemption from the rule of one IDF per floor must be approved by the UniversityRepresentative on a case by case basis. Access switches and UPSs are equipmentcommonly used in IDFs.2. The TRs described above shall be designated for the exclusive use of the followingtelecommunication systems:a. Voice systemsb. Data network systems; including uninterruptible Power Supplies (UPS) both rack-mountand stand-alone supporting these systemsc. Wireless network systemsd. Cellular telephone and in-building DAS systemse. Video surveillance systemsf. Access control systemsDIVISION 27 – COMMUNICATIONS: DESIGN GUIDEFebruary 2018Page 4 of 54

UC Santa Cruz – Division 27 – Communications: Design GuideTR Use RestrictionsNo TR shall be used as a passageway to other equipment rooms, power transformers, custodialequipment, or any other function that would require access for reasons other than service andmaintenance of the communication equipment and cabling they house.TR’s shall be designed and provisioned according to the requirements in ANSI/TIA-569.Design RequirementsTelecommunications Spaces shall be:1. Dedicated to the building’s telecommunications function and related support facilities and shallnot be shared with electrical, building services or any equipment other than those required indirect support of the telecommunications equipment and services. Nor shall they be located nearpotential sources of electromagnetic interference (EMI), radio frequency interference (RFI) suchas induction devices, transformers, ballasts, power supplies, elevator equipment, generators,motors, X-ray generators, photo copiers, microwave ovens, and similar equipment or sources ofmechanical vibration. Take care to design Distributed Antenna System uplink devices so as notto interfere with campus systems.2. Located above water level and not in a place subject to any corrosive atmospheric orenvironmental conditions.3. Located as close as practical to the center of the area served and preferably in the core area.Avoid locations that limit expansion such as structural steel, stairwells and elevator shafts,outside walls or other fixed building walls.4. The average horizontal cable run is 150 feet or less and no individual cable run shall exceed 295feet; minimizing the length of the backbone and horizontal distribution cables. Unlisted Buildingentrance cables shall not be longer than 50-feet once they exit the incoming conduit, as requiredby the California Electrical Code.5. Easily accessible and accessed directly from public hallways and not through offices or otherutility spaces.6. Have easy access to distribution cable pathways.7. Vertically aligned (Stacked) within a multistory building. Horizontal pathways shall terminate inthe TR located on the same floor as the area being served.8. Meet Seismic Design Category D requirements.9. Equipment and piping not related directly to the support of the telecommunications function shallnot be installed in, pass through, pass overhead or enter the telecommunications space. Pipesfor sprinkler heads located within the room shall not be located directly above electronicequipment racks and/or cabinets.10. A TR numbering scheme is to be applied for new and existing facilities. The first number will bethe last three digits of the CAAN, all TRs located in the basement are to be labeled “0”. The firstTR will be 0.1 with each successive TR to be number 0.2, 0.3 and so on. All 1st floor TRs areDIVISION 27 – COMMUNICATIONS: DESIGN GUIDEFebruary 2018Page 5 of 54

UC Santa Cruz – Division 27 – Communications: Design Guide1.1, 1.2 etc. “0” is not to be applied to any TR room. The actual room number will be at the end.Example: The first TR on the first floor of the Communications building would appear as “1751.1-1234”.11. A TR must be a rectangular room with no obstructions or protrusions (beams, columns, etc.) thatdecrease the usable square footage available in the room.12. TRs shall not service WAOs on more than one floor except as previously noted in this documentwith reference to existing buildings.TR Room Construction Guidelines1. Enclosing Wallsa. TR walls shall extend to the structural ceiling above.b. Fire rating of TR walls shall meet all requirements of the A.H.J. that are typically 1 hour,verify with the University Representative.c. Penetration of rated TR walls shall be fire stopped.2. Ceiling: A suspended, false, lay-in, or hard lid ceiling shall not be installed over any TR floorspace. Minimum clear ceiling height shall be 10 feet (10'). In remodels of existing structureswhere HVAC needs cannot be met without a false ceiling, this rule can be waved with the writtenapproval of the University Representative. This exemption must be approved by the Universityon a room by room basis.3. Floora. Do not design raised floor systems for TRs regardless of the set of functions they perform.TR floors should be floor slab, no raised or false floor.b. Floor finish shall be smooth, dust-free, and not susceptible to static electricity build-up.Acceptable finishes are low static composition tile, static dissipating tile (SDT), or sealedconcrete.4. Door: Provide 3 ft. 0 in. wide X 7 ft. 0 in. high door, opening outward, with a card reader lock thatsupports brass key access for emergency use. ADFs require double-doors.5. Windows: TRs shall not have windows.6. Water Infiltration: Measures must be taken to prevent water intrusion. Water, sewer, chemical,or drain piping of any kind shall not be routed through/within a TR.7. Sprinkler Systems: If codes require fire protection sprinkler system heads within a TR, thesprinkler heads shall be the high heat type and shall be protected with a wire cage to preventaccidental discharge. Do not install sprinklers directly above the equipment racks.a. Note: For TRs that support the ADF or BDF functions consider installing a standalone drypipe sprinkler system.DIVISION 27 – COMMUNICATIONS: DESIGN GUIDEFebruary 2018Page 6 of 54

UC Santa Cruz – Division 27 – Communications: Design Guide8. Wall Plywood Sheeting: Provide sufficient number of 4 ft. X 8 ft., ¾ in. thick Grade A-C, certified/stamped as fire retardant and painted with two coats of white fire-retardant paint plywood sheets,to cover all four TR walls. Fire retardant stamps shall be visible after painting. Sheets shall bemounted securely to walls with 8-foot length vertical, 4-foot or less width horizontal. Bottom ofsheet shall be at six inches (6") A.F.F.TR Room Sizing Guidelines and Two (2) Typical TR Room Layouts1. The size of the TR is dependent upon the size of the area that the room will serve and thevariety of equipment installed within the room. The TR shall provide enough space for allplanned termination and electronic equipment and cables that will be installed within the TR;including any environmental control equipment, power distribution/conditioners, door accesscontrollers and other security systems, in-building cellular equipment and uninterruptible powersupply systems. Special consideration needs to be given to space requirements for DistributedAntenna Systems and back-up batteries required.2. TR Sizinga. If the Gross Square Footage (GSF) is between 1,000 and 10,000 sq. ft., the IDF shall be12 ft. long X 9 ft. wide.b. If the GSF is between 10,000 and 17,000 sq. ft., the IDF shall be 14 ft. long X 9 ft. wide.c. If the GSF exceeds 17,000 sq. ft. the IDF shall be 17 ft. long X 10 ft. wide.d. If a second IDF is required to manage the horizontal cable placement run distance limit of295 ft. (90 meters), size the second IDF per the GSF guidelines explained above.e. When a TR supports the BDF and ADF functions, dimension that TR at a minimum of 22 ft.long X 10 ft. wide.f. When remodeling existing buildings, it is permissible to use cabinets or smaller TR sizingwith written approval of the University Representative on a case by case basis.3. The TR sizes listed above are minimum requirements, and provide a good starting point for theprogramming phase of a project. Depending on the services and functions performed by thebuilding's TRs, such as serving as an ADF, or serving a building with high density of WAOs, orinstallation of DAS equipment additional space and fire ratings may be required. ADFs andBDFs for larger size buildings may require additional rows of equipment racks or cabinets notaccounted for in the above sizing guidelines.4. Typical TR Layouts: It is always preferable to size TRs with enough length so that a single row ofracks is sufficient to house all equipment and cabling. The following guidelines referenceclearances for equipment and cross-connect fields housed in TRs.5. Provide the following clearances for equipment and cross-connect fields in TRs.a. Allow a minimum of 36 inches (36") of clear working space in front and 42 inches (42") atrear of equipment racks measured from the front and rear wire managers.DIVISION 27 – COMMUNICATIONS: DESIGN GUIDEFebruary 2018Page 7 of 54

UC Santa Cruz – Division 27 – Communications: Design Guideb. Allow a minimum of 36 inches (36") of clear working space in front and at rear ofequipment cabinets.c. Allow for 8-inch depth off wall for wall-mounted equipment.d. If multiple equipment rack rows are required, provide a minimum 36-inch aisle betweeneach row of racks measured from the face of the equipment installed in the racks. Inmultiple rows, fronts of each rack shall face each other.e. A minimum aisle clearance of 36-inches is required at one end of an equipment rack row.Clearance shall align with TR doorway.f. In many cases, equipment and termination hardware may extend beyond racks andbackboard mounting surfaces. Clearance is measured from the outermost surface of thesedevices, rather than from the mounting surface of the rack or backboard.6. IDF/ADF Racks, Patch Panels, Fiber Panels, Cable Management design considerations.a. 19” 7’-tall (racks are 24.75" wide) seismic category D rated seismic relay racks shall beused.b. A 7' tall, 6.25" wide, double sided vertical cable manager shall be placed between racksand at the ends of each rack row. Wider vertical wire managers can be utilized if requiredto accommodate more incoming cabling or patch cord containment and management.c. 2RU, 48-port patch panels shall be used for horizontal cabling.d. A 2RU horizontal cable manager shall be placed above and below each copper patchpanel.e. Mount 2RU, 48 port voice cross-connect patch panels below WAO station cable patchpanels. The number of voice cross-connect jacks shall be equal to the number of pairs inthe voice riser cable pair count.f. A 2RU horizontal cable manager shall be placed above and below each voice crossconnect patch panel.g. The fiber connector housings shall be placed in the center rack of the row, in the top-mostposition of the rack. A fiber connector housing does not require its own horizontal cablemanagers.h. The rack with the fiber connector housing will be loaded with one less 48-port stationcabling patch-panel than other racks.i. 2 RU fiber panels shall be used for IDFs. 4 RU fiber panels shall be used for BDFs andADFs.j. Fiber terminations shall be fusion spliced LC pigtails.DIVISION 27 – COMMUNICATIONS: DESIGN GUIDEFebruary 2018Page 8 of 54
