Section 2 - TELECOMMUNICATIONS ROOMS AND CABLE TERMINATION
2.1 OVERVIEW
- 2.1.1 DEFINITION
Telecommunication rooms are
special-purpose rooms that house telecommunications equipment and
wiring. These rooms have specific requirements due to the nature,
size and complexity of the equipment and wiring housed in the
room.
- 2.1.2 SPACE
There are two different types of
telecommunications rooms within a building, each supporting
critical functions as part of the building wiring and
communications systems. In general, each room must be large enough
to accommodate the wiring and equipment, which will be located
within them, plus additional space for growth. The two types of
rooms are:
- The Telecommunications Distribution Equipment Room (TDER),
Main Distribution Frame (MDF) or Main Cross-connect (MC). MC
will be used here. There is normally only one MC per building.
This room may serve as what is sometimes called the node room
and house Data Switches, Routers, and Telecom related electronic
equipment.
- The Wiring Closet, Intermediate Distribution Frame (IDF),
Intermediate Cross-connect (IC), Horizontal Cross-connect or
Telecommunications Room (TR). TC will be used here. There is
at least one TC per floor. More than one TC per floor is
required when the terminated wiring distance between any
communications jack and the TC exceeds 295 feet (90 meters).
The
preferable minimum size for a Telecommunication Room is 64
square feet and the preferable dimensions for this room are
8’X8’. In no case shall this room be less than 64 square feet,
with the minimum dimension of any side being 8 feet. This room may
be shared with telephone equipment and data network equipment and
racks. Telecommunications Center shall be contacted for final
dimension approval.
- 2.1.3 GENERAL
Project specifications will
indicate that Telecommunications Center personnel or its designee
are responsible for furnishing, installing and terminating the
various types of communications cabling, racks, panels and other
items specified in Section 2. All work shall comply
with the National Electrical Code, Local Building Codes, and the
University of Mississippi Physical Plant standards.
NOTE: Telecommunications rooms may vary according to
the size of the building, number of floors, tenancy
characteristics and telecommunications services required.
Consideration to the future needs of the facility and the end
users is a necessity. Telecommunications Center will have final
approval on room dimensions. Electrical panels, other
than those exclusively servicing the telecommunication room in
which it is located, are strictly prohibited in telecommunications
rooms. Services, which are not telecommunication related, shall
also be prohibited in these rooms. This includes, but is not
limited to, janitorial services, supply storage, departmental
storage, etc. There shall never be an exception to these
restrictions. Fire alarm and security panels are not permitted in
telecommunication rooms. A 50 percent growth factor
shall be built in and provided in each riser unless otherwise
specified; consequently any cable or conduit work that pertains to
telecommunications must be designed and/or approved by
Telecommunications Center. Project specifications will include
this growth factor. To facilitate the proper
installation, routing and placement of cables, wires, premise
equipment and terminal fields, telecommunication closets shall be
located on each floor, as close as possible to the middle of the
building and stacked one above the other, unless otherwise
instructed or approved by Telecommunications Center. Architects
and Engineers must pay special attention to telecommunication
closet locations to overcome distance limitations. The total
distance of the conduit path, from outlet to the TC or MC, when
the MC also serves as a TC, shall not exceed 295 feet (90 meters)
including termination loss. Every PC or other single
device with a network connection must be cabled back to the
nearest telecommunications closet in the building. The
telecommunication room(s) shall house all and only the equipment
directly related to the telecommunications systems and its
environmental support systems. "As Built" drawings

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. When cable is secured by tiewrap or other
fasteners they shall not be pulled so tight at any point that the
cable jacket is crushed flat or indented. Use wireways
on verticals of relay racks to accommodate the fiber cable on the
backside and the fiber patch cords to the front of racks.
Jumper or 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 of 20 ft. slack left in a terminal room,
mounted in a circular configuration on fire rated plywood (3/4
in.). This is necessary in the event of a fiber break.
All fiber strands shall be terminated in accordance
with the industry standard color codes. Label all fiber
cable and all fiber strands at termination locations.
Telecommunications Center will provide fiber cable nomenclature.
Test all strands using an optical time domain
reflectometer (OTDR) and optical loss test sets (OLTS). Fiber
cable runs less than 100 meters in length shall be tested with an
approved light meter. Provide computer readable test results of
each fiber strand to Telecommunications Center. See Section 6. for
additional testing information.
