Network Infrastructure Design StandardsUniversity of Houston4.0 GENERAL REQUIREMENTS4.0.1 CODES, STANDARDS AND REGULATIONSOn network infrastructure projects at University of Houston, comply with federal, state and localcodes, rules, regulations and ordinances. In addition, adhere to the University of HoustonMaster Specification, available online -specs/If this document presents a compliance conflict, promptly bring it to the attention of the UITNetwork Standards Coordinator in writing. Please include the specific provision in this documentand state the rule, regulation, industry standard, code provision, manufacturer requirement orpolicy that is in conflict. Where these standards are more stringent than the requirements ofother applicable authorities, these provisions will apply.For a list of agencies, standards and codes specifically included by reference, see MasterSpecification 27 0500 Communications General Provisions.4.0.2 CERTIFICATIONS, WARRANTY AND PROJECT EXECUTIONDetails related to the following topics formerly included in this document are covered in MasterSpecification 27 0500 Communications General Provisions: Contractor CertificationWarrantyDelivery, Storage and HandlingSequence and SchedulingUse of the SiteContinuity of Services5.0 NETWORK FACILITIES5.0.1 TERMINOLOGY: ACRONYMS, ABBREVIATIONS AND DEFINITIONSFor a full list of relevant acronyms, abbreviations and agencies, see Master Specification 27 0500Communications General Provisions.Building Distribution Frame (BDF, also known as BICSI Entrance Facility) is the area where thedemarcation between the inter-building and intra-building cabling systems is affected. Thissecurable room is to be dedicated to this purpose, with no other building services sharing thespace.Version 1.27i5Rev. 3/23/2020
Network Infrastructure Design StandardsUniversity of HoustonHorizontal Cross-Connect (HC) is a cross-connect allowing horizontal cabling to beinterconnected to backbone cabling.Intermediate Distribution Frame (IDF) provides for demarcation between the per-floorhorizontal customer service cabling and the building’s data, voice and video backbone cabling.This room contains the electronic equipment that transitions between the building backboneand the end user's telecommunications equipment. This securable room is to be dedicated tothis purpose, with no other building services sharing the space.IDFs are allocated to each floor of a building and house the communications equipment andrelated wiring that serves that specific floor. Several IDFs may be located on a single floor inorder to maintain the cable length limitations specified within particular standards.Lateral Fiber (LF) is the term used to describe a fiber optic cable of a smaller fiber count (12 – 48is typical) that originates from a BDF and terminates into the Metro Fiber for its networkconnectivity.Main Cross-Connect (MC) is the cross-connect normally located in the BDF for cross-connectionand interconnection of entrance cables, first-level backbone cables, and equipment cables.Main Distribution Frame (MDF, also known as BICSI Entrance Room) is the maintelecommunications service entrance into the campus. It may or may not be where the BDF islocated.Metro Fiber (MF) is the term used to describe high fiber count cables (144, 288, etc.) thattraverse the campus, have midpoint splice cases, and act as the fiber backbone of the campus.Network Facility (NFs, also known as Telecommunications Rooms [TRs] or BICSI EquipmentRooms [ERs]) are environmentally controlled spaces and secured rooms housingtelecommunication and network equipment such as data, voice and video components and theirassociated connectivity infrastructure. The types of Network Facilities are Main DistributionFrame, Building Distribution Frame, Intermediate Distribution Frame and TelecommunicationEnclosure.Telecommunication Enclosure (TE) is a secured case, cabinet or housing for telecommunicationsequipment, cable terminations and cross-connect cabling.5.0.2 REQUIREMENTS5.0.2.1 GENERALRefer to Master Specification 1100 Network Facility Fittings for information related toauthorized products and installation requirements. The guidelines published by ANSI/TIA/EIA and BICSI (as modified, expanded or limited bythis document or the Master Specification) govern both design and construction of NFs.Version 1.27i6Rev. 3/23/2020
Network Infrastructure Design Standards University of HoustonSubmit all variances to UITNS for approval.Position NFs to comply with TIA/EIA distance limitations.Stack NFs one above the other whenever possible.Clearly describe the building service entrance for communications and specify in Drawingdetails how the building connects to the campus network.Route cable paths so that the total cable length between the telecommunications outlet andits termination in the NFs is not greater than 90 meters.Do not route plumbing, HVAC or electrical conduit through or above the NF, except forsprinkler systems that directly serve the NF (no pass-through sprinkler trunks or temporaryservices are allowed).Use sprinkler heads that are rated for high temperature.Cage the sprinkler heads.Do not place electrical or any other utility panels in a NF.Doors and Locks for NFs Use a windowless, solid core door measuring at least 36” wide by 80” tall.Mount doors to open outward.Core the locks with a campus standard system to accept the NF standard keying of 3ILxxx asprovided by the University of Houston Lock Shop.Equip all doors with an online card reader system.After installation, obtain keys for NFs from UITNS as needed.Security Secure NFs to be protected from environmental concerns, hazards and theft.Configure NFs so that UIT staff has full-path access throughout.Floors Design floors to bear loads of at least 50 pounds per square foot.Use vinyl composition tile or sealed concrete floor material.Do not use carpet.Conduits and SleevesThe size and placement of conduits and sleeves need to facilitate frequent additions, moves andchanges to the telecommunication systems. Once the number and size of conduits are determined, add two additional, empty conduitsfor growth.For the communications service entrance pathway, design for a minimum of four 4-inchconduits from the Building Entrance Point to the MDF.Use 4-inch conduits entering the building, with some type of sub-space partitionin
