OVERVIEW
All
telephone, data, and CATV station cabling shall be continuous cabling from the
MTR or the TER to the communication outlet. All station cables will be free of
kinks, chafes, and tight bends. Any ceiling tiles removed by the contractor for
cable installation will be re-installed in good condition. Replacement of
damaged tiles is the contractor’s responsibility at no cost to the university.
The
building occupant's present and future requirements will determine the needs of
multiple jack outlets. Final approval for the layout of jacks shall rest with
the Information Technology Communication Services. During the programming stage
Information Technology Communication Services, consulting with the building
occupant(s), will supply the jack layout desired to the project architect for
inclusion in the project specifications.
All
analog voice connections shall terminate on black RJ-45 eight (8) conductor CAT
5E modular jack assemblies. The Quickport faceplate shall be White and will
support 4 modular jack assemblies. The voice jack color shall be Black and will
be placed in the top port(s) of the wall plate. If only one voice jack, it
should be terminated in the upper left port. Wire color-coding and termination
shall be per EIA/TIA-568-B.2 specifications. If no other jacks are to populate
the faceplate, blank modules are to be used to fill the spare positions. The
blank modules are to be the same color as the Quickport faceplate.

FIBER OPTIC CABLE
10.2.1
GENERAL
Multi-mode
and single-mode fibers are both utilized at the University. In all cases of
multi-mode-fiber installation, 62.5/125MM will be used.
Direct
burial of fiber optic cable is not allowed.
When
installing fiber optic cable in ductwork and manholes between buildings, there
shall be a minimum of one complete loop; minimum of 30 feet in length, in the manhole
and it shall be pulled in a protective liner inside the manhole to prevent
damage to the cable.
All
fiber optic cables shall be terminated with ST type connector and properly
connected to the fiber enclosure. Fiber cable metallic sheath if attached shall
be properly grounded.
When
installing fiber optic cable, in existing conduit that is not Multi-Cell or
does not contain flow duct, it shall be pulled in a protective textile innerduct,
minimum 3/4 inch inside diameter. When placed in a cable tray or on a runway
where there is the possibility of someone standing, walking or sitting on the
cable, it shall be placed inside a protective liner. When floor duct is
utilized one chamber will be used exclusively for the fiber.
All
cable placed along runways, relay racks and distribution shelves shall comply
with the manufacturer’s minimum bend radius requirements for that particular
type cable. Cable is to be secured by Velcro so as not to be pulled tight at
any point that causes the cable jacket to be crushed flat or indented.
Use
vertical and horizontal wire management on relay racks to accommodate the fiber
cable to be dressed into the fiber terminating enclosures.
Fiber
optic patch cords are to be used to connect different fibers together for
continuation of service. Do not wrap a jumper completely around a routing guide
or other type bracket. When using routing guides on a relay rack always use the
rear portion of the guides to hold vertical jumper runs and the front portion
of the guides to hold horizontal jumpers. Always use the front routing guide to
enter or leave a housing.
There
should be a minimum 30 ft. service loop left in a TER, mounted in a circular
configuration on fire rated plywood (3/4 in.) or left in the wiring tray.
All
fiber strands shall be terminated in accordance with industry standards and
layed out in order of industry color codes.
Label
all fiber cable and each fiber strand at termination locations. Information
Technology Communication Services will provide fiber cable nomenclature.
Test
all strands using an optical time domain reflectometer (OTDR) and/or optical
loss test sets (OLTS). Fiber cable runs less than 100 meters in length shall be
tested with an approved light meter. Provide hardcopy test results of each
fiber strand to Information Technology Communication Services. See Section 6
for additional testing information.
10.3
UTP
All
four pair UTP cable installed at the University will be at a minimum CAT5E and
rated at least 400Megahertz.
All
UTP riser cable installed at the University will be CAT3 rated and 100 pairs
minimum.
10.4
COAXIAL
All
coaxial cable installed at the University for the intended purpose of cable TV
distribution will be RG6 quadshield.

MISCELLANEOUS AND SPECIAL SITUATIONS
11.1
GENERAL
11.2
WIRELESS LANS
All
conduit outlets for house phones, corridor phones, courtesy phones and pay
phones are to meet height and location requirements in the Americans with
Disabilities Act (ADA) for handicapped access. This standard only refers to
telecommunication requirements. All other utilities are the responsibility of
the department involved.
11.1.2
PUBLIC PAY PHONES
TTY,
Text Telephones (formally TDD), must be accessible to handicapped individuals.
The
height of the coin slot shall be 48 inches for all installations.
If
a total number of four (4) or more public pay telephones (including both
interior and exterior phones) is provided at a site, and at least one (1) is in
an interior location, then at least one interior public text telephone shall be
provided.
Where
pay phones or pay phone enclosures require electrical service, such electrical
service and connections shall be provided by Physical Plant or an electrical
contractor.
NOTE:
Campus payphones are scheduled to be eliminated by the end of calendar year
2003.
11.1.3 SWIMMING POOLS
When
poolside telephone service is desired and there is no building near to hang
attachments on, install a pedestal and run a 1 1/4-inch conduit to the
location. If the conduit length is longer than 80 feet, install a pullbox
according to NEC. All fittings and jacks must be watertight.
11.1.4
EMERGENCY AND ELEVATOR TELEPHONES
Note
the electrical requirements for outside standalone mounted Emergency Phones.
Electrical requirements will be provided by Physical Plant or an electrical
contractor.
11.2
WIRELESS LANS
Due to the
unique nature of wireless LANs and the probable interference between access
points if frequency allocations (channel assignments) are not controlled, only
wireless LAN equipment installed and configured by Information Technology
Communication Services (ITCS) will be permitted on campus. UofL has
standardized on the Cisco Aironet 1200 Series Access Point. This solution
conforms to the IEEE 802.11 standard and is fully compliant with the WECA
(Wireless Ethernet Compatibility Alliance) Wi-Fi standard.
Information for
accessing the wireless network can be found at http://www.louisville.edu/it/wireless/
WIRELESS LAN
ACCESS POINT COVERAGE
The following
are the initial starting points for the recommended number of access points to
provide wireless LAN coverage in the various types of spaces on campus. A site
survey is recommended during the design stage of the project to determine the
recommended access point quantities and locations. The quantities stated below
are initial guideline numbers only.
NOTE:
The University’s wireless network does not replace the wired network, it
complements it. If you are running a computer from a fixed location, that is
for example, a computer lab, a residence hall room, or an office location, then
a traditional hard-wired ethernet connection is required. This is primarily due
to degraded performance implications associated with wireless LANs.

concurrently, for example, using
the network along with the instructor to access web pages, low to medium
quality streaming video, large file transfers, CAD drawing retrieval, etc.
Medium - all 21-40 students are using the network,
but not in a coordinated fashion, for example all working on a project
independently as part of the classroom instruction.
Light - all 41-60 students using the network on a
more or less casual basis and concurrency of use is random and more or less
minimal. Also in this category is highly concurrent use of low bandwidth
applications such as email.
NOTE: A wireless connection should not be substituted for the hard-wired data jack at the instructor location(s) in classrooms, lecture halls and auditoriums.
