1IntroductionThe Office of Information Technology/Networking and Telecommunications Services

(OIT/NTS) is responsible for providing voice, data, and videoservices for the University ofMinnesota. Every effort is being made to keep the rates for these services as low as possiblewhile still providing service and maintenance in a timely manner. OIT/NTS is constantly

evaluating emerging technologies and equipment so that we can continue to offer the mostreliable, up to date, and cost-effective services.

It is essential to design the telecommunications systems to meet present and future voice and

data communication needs. Horizontal and vertical wiring and the pathways andcommunication rooms should be considered an integral part of the building infrastructure and

therefore capable of future growth as new technology and customer needs change.

Refer to the NTS Web page atwww1.umn.edu/nts/wiring3.shtmlfor the most recent revisionof these standards. The standards herein apply to the technologies in use at the time of the

latest update to this document. The implementation of newer technologies shall requireadherence to the standards written at the time of that implementation.

2General StandardsIntroduction

Voice and data projects that are released for bid should be bid separately from and not includedwith security, audiovisual, building control systems, or other equipment or materials that are

not directly associated with the independent high speed data or voice communications system.

Telecommunications systems include vertical and horizontal copper and fiber optic wiring aswell as the associated termination hardware on both ends. The system includes pathways and

conduits; equipment racks; frames; wire management systems; communication rooms; and theelectrical, mechanical, and environmental equipment required to support them.

The space and facilities in these specifications are designed to meet the telecommunications

requirements (voice and data networking) for university buildings only. These specifications

are intended to allow OIT/NTS to meet the telecommunications requirements of the Universityover the lifetime of the buildings. It is essential that OIT/NTS shall be consulted prior to andthroughout the planning and design process to ensure that present and future voice and data

service requirements can be met.

OIT/NTS MUST provide prior written approval for any deviations from these standards, orOIT/NTS will not assume financial responsibility to upgrade the facility to performance

expectations. Where ambiguity or questions arise to specific details not mentioned in thesestandards, appropriate TIA/EIA, NEC, and BICSI standards shall apply.

All applicable building codes must be strictly adhered to in regards to telecommunicationsservices. OIT/NTS cannot authorize variations to any building codes.

Construction specifications are a main ingredient of an Information Technology system.Information Technology systems shall adhere to these specifications in order to be

functional in a wide variety of communications applications. This document does not allowor condone the avoidance of following any of the Laws, Standards, or Procedures of any,

but not limited to the following:

3Special RequirementsIntroduction

The OIT/NTS Wiring Standards publication is intended to address standard Universityinstallation practices, with safety and performance being the most important factors. While

these standards are carefully monitored to ensure that the hardware and practices aretechnologically current, it is possible that some applications may require special consideration.

University of Minnesota buildings frequently contain special purpose facilities and equipmentwith unique telecommunications requirements. Special telecommunications requirements may

require deviation from these specifications. OIT/NTS needs to be notified of these specialrequirements as early in the design process as possible.

The following is a short (but not all-inclusive) list of facilities and equipment thatcommonly have special telecommunications requirements:

o Data centers or computer roomso Computer labs or classroomso Video conferencing roomso Video equipmento Laboratorieso Medical imaging equipmento Scientific equipmento Public telephoneso Internet kioskso Wireless networking

Installation designs and practices not specifically identified as standard in this documentwill require appropriate OIT/NTS approval before connection to the campus voice or datanetwork. To that end, any department requesting a non-standard installation of cabling

infrastructure, voice/data jacks, or other items not specified in these standards shouldsubmit a written explanation of the requested variance to an OIT/NTS project coordinatorfor review.

4Entrance FacilitiesIntroduction

The entrance facility is the location where the pathways for communications services penetratethe building to connect to the voice and data systems within the building. The entrance

facilities are generally 4-inch rigid steel conduit that extend from the perimeter of the buildingto the telecommunications main equipment room (MDF).

OIT/NTS shall designate the shortest practical route for the communications cable toconnect from the building to the point of connection with the university telephone and


5/43



4/26/2007

network cabling systems. Conduit shall be installed within the facility from the point of

entry to the telecommunications main equipment room.

Diverse facilities entrances are required for all new buildings that will house voice and dataequipment when the scope and importance of the facility are determined to require it by

OIT/NTS and the end-user.

In the event that diverse cable facility entrances are not deemed necessary, provisions shallbe made for four 4-inch conduits for access from the university cable system to the

telecommunications main equipment room. Each of these conduits must be labeled "TELEMDF ONLY."

Entrance facilities must adhere to all BICSI requirements in Chapter 6 of theTelecommunications Distributions Methods Manual (TDMM), (11th edition or subsequent

releases). (Visit www.bicsi.org for purchasing information.) OIT/NTS must approve anydeviations from the BICSI TDMM.

5Telecommunications Rooms5.1General Requirements

Introduction

Telecommunications rooms are special-purpose rooms that house telecommunicationsequipment and wiring. These rooms have specific requirements due to the nature, size,

and complexity of the equipment and wiring housed in these rooms.

There may be up to three types of telecommunications rooms within a building, eachsupporting critical functions as part of the building wiring and telecommunications

systems. In general, each room must be large enough to accommodate the wiring andequipment that will be located within it, plus provide additional space for growth over

the lifetime of the building. The three types of rooms are:

o Main equipment room/Main Distribution Frame (MDF)o Communications rooms/Intermediate Distribution Frame (IDF or riser

rooms)

o Terminal space/satellite roomsThe following standards apply to all three types of telecommunications rooms:

PROHIBITED: Using telecommunications rooms as a route for other facilities topass through.

PROHIBITED: Using boiler rooms, air exchange rooms, janitorial closets,electrical distribution closets, or areas with water heaters and wet sinks for

6Bonding and GroundingIntroduction

The NEC defines bonding as, The permanent joining of metallic parts to form an electrically

conductive path that ensures electrical continuity and the capacity to conduct safely any currentlikely to be imposed. A ground is defined as, A conducting connection, whether intentionalor accidental, between an electrical circuit or equipment and the earth or to some conducting

body that serves in place of the earth.

The purpose of the grounding system is to direct potentially damaging currents away frompeople and sensitive network equipment by creating a low impedance path to earth ground for

electrical surges and transient voltages. This serves to minimize the detrimental effects of thesecurrents (which include degraded network performance and reliability, as well as increased

safety risks).

The grounding system must be intentional, visually verifiable, and adequately sized to handleexpected currents safely. The grounding system shall be designed and installed in accordance

with the NEC and with the BICSI TDMM, Chapter 8 (11th

edition or subsequent releases),TIA/EIA-942, and J-STD-607-A.

6.1Busbars Each communications room in a building shall have a grounding busbar, typically

installed in a lower corner of the plywood backboard at least 6 inches above thefinished floor, and as close as practicable to any electrical panelboard serving the

room.

The main equipment room or entrance facility shall house the TelecommunicationsMain Grounding Busbar (TMGB), and each other equipment room shall house a

Telecommunications Grounding Busbar (TGB).

Busbars shall be a minimum of inch thick, of electrolytic tin plated copperconstruction, and must be predrilled to accept standard two-hole lugs. The TMGB

shall be 4 inches high, a minimum of 20 inches long, and of variable length to

accommodate the expected number of lugs and allow for future growth. The TGBshall be 2 inches high, a minimum of 12 inches long, and of variable length.Currently approved busbars are Panduit GB4 series for MDF and GB2 series for

IDF.

6.2Telecommunications Bonding Backbone The busbars on each floor shall be bonded to the Telecommunications Bonding

Backbone (TBB). The TBB shall be routed in as straight a line as possible and be

continuous, with no splices, from the TMGB to the top floor TGB. It shall be sizedin accordance with J-STD-607-A (See Table 1). The bend radius on any necessary

bends in this cable should be greater than 8 inches.

building, the TGBs shall be connected at the top floor and at a minimum of everythird floor below by a Grounding Equalizer (GE), which is equal in size to the

TBB.

6.3Cables Each conductive multipair cable in a building shall be grounded at both ends via a

bond attached to the cable armor (which accepts a standard two-hole lug). The bond

shall be Electric Motion Companys EM 2BBx bond, unless a substitute isapproved in advance by OIT/NTS.

6.4Rack Grounding

Electrical continuity throughout each rack or cabinet is required to minimize safetyrisks. The racks shall be assembled using paint-piercing grounding washers(Panduit Part no. RGW, or an OIT/NTS-approved substitute) and antioxidant (per

the recommendations of the manufacturer). An electrostatic discharge port kit(Panduit RGESD, or an OIT/NTS-approved substitute) shall be placed on the rack

(on the right side when facing the rack) at 48 inches above the floor. All bondingconnections to the rack shall be made with thread-forming screws (Panduit Part no.

RGTS, or an OIT/NTS-approved substitute), or the threads must be cleaned of allpaint or residue (per the NEC).

In locations with multiple racks, the rack shall be connected to the commonbonding network with a 6 AWG conductor and a copper compression HTAP. Inlocations with single racks, a 6 AWG conductor to the busbar is sufficient. The

common bonding network is a 2 AWG continuous conductor placed below orabove the racks. Refer to TIA/EIA-942 and IEEE-1100 for designrecommendations.

6.5Pathway Grounding Any metallic component, including equipment, ladder racks, enclosures, cable

trays, etc., must be bonded to the grounding system. Provisions must be made tobond individual segments of ladder rack and basket tray together in order to make

them electrically continuous. Any metallic conduit that carries a groundingconductor and is greater than 3 feet long must have both ends bonded to the

conductor with a bonding jumper no longer than 12 inches and fastened with acompression HTAP to the conductor on one side and to the conduit on the other.

6.6Equipment Grounding Although AC-powered equipment typically has a power cord that contains a ground

wire, the integrity of this path cannot be easily verified. Thus, many equipmentmanufacturers require grounding above and beyond that which is specified by local

electrical codes, such as the NEC. Always follow the grounding recommendationsof the manufacturer when installing equipment.

6.7Electrical Service When an electrical panelboard is located in a telecommunications room, a 6 AWG

bonding conductor shall be run from the busbar to the electrical service ground.When an electrical panelboard is not located in the room, a 6 AWG bonding

conductor should be run from the busbar to the nearest electrical panelboard (where

feasible).

o Approved HTAPS: Panduit HTWC series Burndy YH series (when used with clear covers) or an OIT/NTS-

approved substitute.

6.9Testing and documentationThe grounding system shall be documented by means of a diagram showing thelocations of the busbars and the size of the conductors, indicating all connections

between conductors from the busbars or TBB back to the building electrical groundingsystem. This includes: connections to building AC panelboards, building steel, the

building electrical service ground, connections between the busbar(s) and the TBB. Ifnot connected with a two-hole lug, the connection type of any bonding connection

(HTAP, clamp, etc) between the busbar and the building ground point should be

specified on the drawing.

To ensure that bonding connections from the busbar to infrastructure within thetelecommunications spaces are of low resistance and that the impedance to ground is as

low as possible, the following checks shall be performed.

Lugs: Visually check that the conductor is visible in the window of the lug toensure that it was fully inserted, and that the lug is properly crimped. Check that thelug is fastened through both mounting holes, that the connection is tight, and that

antioxidant was used (if necessary).

HTAPs: Ensure that the mark left on the HTAP indicates that the appropriatemanufacturer-recommended die was used for that HTAP, and that the connection isprotected by a clear cover that allows visual inspection.

Racks: Visually check that the racks have been assembled with paint-piercingwashers or are constructed so as to make such measures unnecessary (i.e. welded).

Conduits: If a bonding conductor is routed through a metallic conduit more thanthree feet long, ensure that both ends of the conduit are bonded to the conductor

with a suitable method, avoiding sharp bends in the cable. Looping the conductor

itself through the conduit bonding collar is prohibited.

Measurements: Ensure that the resistance of the following connections is less than0.1 ohms:

o Lug to HTAP for any connections to Common Bonding Networko Rack bonding lug to any rack section (the paint-piercing washers make

good test points)

o Bonding lugs to busbar, cable tray, and cable bond7Intrabuilding Backbone Riser Facilities

Figure B: Conduit to Cable Tray Configurations

9.1J-HooksThe use of J-Hooks to support horizontal wiring in lieu of continuous conduit or a

combination of conduit and wire basket tray is currently under study by OIT/NTS. Atthis time, OIT/NTS cannot document any advantages to using J-Hooks other than for

economic reasons. Numerous questions and concerns have arisen regarding the affectsof EMI (Electromagnetic Interference) on high speed data transmissions when J-Hooks

are used to suspend horizontal wiring systems. Compatibility concerns (including bend

radius control and loading limitations) and EMI susceptibility between cable

manufacturers and J-Hook manufacturers have not been adequately addressed, given thelarge number of products and the various combinations that can be used.

When J-Hooks are to be installed as a substitution for continuous conduit or acombination of conduit and wire basket tray, it is the responsibility of the Architect,

Electrical Engineer, Owners Representative, Professional Voice and Data Consultant, orother requesting party to provide documentation from both the cable manufacturer and

the J-Hook manufacturer stating that their wire and J-Hooks are compatible and willaddress bend radius control, loading limitations, and EMI rejection. A plan showing the

placement of each J-Hook including load capacity and bend radius control must also beprovided to OIT/NTS. OIT/NTS must review the documentation and approve of the J-

Hook System, or OIT/NTS will not bear the responsibility of insuring that the voice and

data systems and services perform to the required data and voice transmission speeds.

10Horizontal Wiring Facilities PROHIBITED: Daisy chaining of conduit from outlet to outlet. PROHIBITED: Splitting copper pairs between jacks. TIA/EIA-568-B-1 states that

"Each 4-pair cable shall be terminated in an eight-position modular jack at the work

area."

PROHIBITED: Sharing the outlet and conduit pathway with other non-telecommunications facilities.

PROHIBITED: Using traditional nylon synch-style tie wraps to bundle cables. OnlyVelcro-style tie wraps are acceptable.

Horizontal wiring technicians and installers shall be certified by the manufacturer of allhorizontal wiring and termination components that they will be installing.

Telecommunications outlets shall be wired with unshielded, twisted pair 24 AWG wire(UTP) with suitable insulation and sheath material to meet or exceed TIA/EIA-568-B.2or equivalent. The wire shall be type communications riser cable (CMR) or

communications plenum cable (CMP) (UL) with rating dependent on the NEC, and itshall be OIT/NTS approved.

When pulling cable in Patient Care areas, it is critical that care is taken to control dust,odors, noise, and aisle clearances. In addition, strict adherence should be given to patient

confidentiality policies of the University of Minnesota.

The current position of OIT/NTS on horizontal cabling is to recommend theinstallation of Category 5E cable. Because of the variety of infrastructure on campus,

OIT/NTS cannot guarantee performance without an upgrade of the infrastructure tosupport higher bandwidth requirements of new technology. For example, installing

Category 6 cabling does not guarantee performance at increased bandwidths without anupgrade of the installed infrastructure/backbone system.

Any cable lubricant to be used during cable installation must meet both performance andcompatibility standards for the cable as specified by the cable manufacturer.

If a building initially is wired with Category 6 cabling, any subsequent wiring shall bedone exclusively with Category 6 cable. Deviation of wiring levels when the original isinstalled with Category 6 is not recommended unless OIT/NTS pre-approves in advance

in writing. Any movement, additions, or changes after the initial installation shall require


29/43



4/26/2007

29

Category 6 cable to be used. One manufacturer's brand shall be used for each component

type throughout a building if the Category 6 wiring system requires the same vendorproducts in order to retain Category 6 performance standards and successful testing.

13OIT/NTS Outlet Labeling Scheme (Jacks)Each jack location in an outlet facility shall be labeled in accordance with OIT/NTS jack-labeling practices. The labeling follows a standard format, indicating the room followed by

the location within the room.

The general requirements for outlet facilities include the following:

The jack naming standard is:XXXX-XX-XXXXX-XX4 characters2 characters5 characters2 characters

The first four characters are the Building Number. Each building in MySoft has abuilding number affiliated with it.

The second set of characters is the floor. Typically these characters are numeric,

indicating the floor number that a jack resides on. Some of the variations from thenumeric floor number are:

o 0Bindicating the Basement Levelo 0Gindicating the Ground Flooro LLIndicating the Lower Levelo MZ or 0Mindicating Mezzanineo 0Pindicating Plazao SBindicating Sub-Basemento SPindicating Sub-Plaza

Please note that the above 0 are a zero not a capital letter O. That is important

when searching the MySoft database.

The third set of characters is the room identifier. These characters indicate the RoomNumber that a jack is located within. These should always be 5 characters in length. We

use 0 to fill any unnecessary place holders. For example if the jack is in room 12, thefive characters would be entered as 00012. Some of the variations from the numeric

room number (according to MySoft Standards) are as follows:

o OSindicating outside of room (i.e.: OS146 indicates the jack isoutside of room 146).

o 0Cindicating a cubicle area in room (i.e.: 0C210 indicates thejack is in a cubicle in room 210).

o HL or 0Hindicating a hallway area near room (i.e.: HL532indicates the jack is in the hallway outside of room 532).

The last set of characters is the specific jack identifier. These two charactersspecifically identify a jack within a room. The jack labeling scheme begins with AA,

incrementing to AB, etc. so that each jack within a room has its own uniqueidentification.

Following are examples of some Exceptions to the Jack Naming Standard:1057-00-CODEB-LU This indicates this jack is for a Code Blue location near Building

1057.

1103-00-CAMPH-AA This indicates this jack is for a Campus Telephone location nearBuilding 1103.

1103-00-COINS-AA This indicates a pay telephone location in or near Building 1103.

1103-00-CRDKY-AA This indicates a Card Key location in or near Building 1103.

1103-00-VATOR-AA This indicates an Elevator location in Building 1103.

1202-00-TRAIL-AA This indicates a construction trailer at Building 1202.

1204-XX-49710-CF The XX is used for the floor to show this is not a legitimate jacklocationthere is NO jack at all. This jack indicates that this is

service for Building 1204, forwarding callers to 612-624-9710.Refer to Remote Call Forwarding procedure for more details.

1728-CX-70025-CF The CX is used for the floor to show this is not a legitimate jack

locationthere is NO jack at all. This jack indicates that this isservice for Building 1728; forwarding callers to a (CX) Centrexline 612-627-0025. Refer to Remote Off-Campus Call

Forwarding procedure for more details.

Any time we have to deviate from the Jack Naming Standard, typically the floor should

be 00. This helps as a quick aid to indicate that this is not a standard jack. The rule ofthumb is that when the JackNaming Stan
