Introduction

1.1

Purpose

The purpose
of this document is to provide the standards requirements for the design and
installation of the structured cables plant to York University faculty
, staff

and
student residences
in
campus buildings, leased sites and underground fibre and to ensure uniformi
ty in the expansion
and maintenance of the wiring infrastructure.


Standards have been developed with reference to the TIA=Telecommunications Industry
Association and BICSI= Building Industry Consulting Services International to ensure the
deployment, inte
grity, reliability and performance and maintenance of the infrastructure for the
University.

York University’s UIT
-

department has defined infrastructure to represent the physical connection in
which services are dependant on to perform all modes of commun
ications. This includes hardware
and sof
tware, w
ired and wireless services that are dependant on the structured cable network to
communication with the outside world.

UIT works closely with a number of internal departments,
external contractors and the gen
eral public to ensure the integrity of the wiring infrastructure
installations comply with the industry requirements. This ensures reliability of services and delivery
of facilities which are not compromising or interfering in the transmission of communica
tions.


The guidelines and standards listed in this document shall be mandatory for the provisioning and
maintenance of all communication services which include the data centres, communication rooms,
and sate
llites sites which communicate

through York Uni
versity’s voice and data networks. This
document applies to the purchasing and installation of fibre, copper and cable wiring as well as the
installation of services.


Defining the standards for the infrastructure will guarantee compliancy with current tec
hnologies
which are dependant on the wiring infrastructure to ensure quality performance.


6

1.1

Owners
h
ip
, Management and Maintenance of the Infrastructure

The ownership of the infrastructure is UIT
-
Infrastructure Operations. UIT
-
Infra Ops is responsible
for the

provisioning,
installation

and maintenance

of all wired facilities that are installed at both
Keele and Glendon campuses. This is however not restricted to other sites

which York University
operates.

This may include but is not restricted to educational s
ites, research facilities, construction
trailers, visiting groups which occupy York space and vendors on campus. This does include the
infrastructure of all residences on campus but does not restrict the type of service utilizing the
infrastructure.

UIT
-
In
fra Ops is also responsible for the management of the wiring infrastructure.
This includes regular wiring upgrades as requires as a result of the development of industry
technologies which are dependant on more sophisticated and advanced wiring.

There are
some sites that UIT
-
Infra Ops does not provide the wiring infrastructure to but does
provide support and maintenance to the services which are used to communication through York
University networks. These sites are reviewed on an individual basis as tenant
/owners of the
buildings may be responsible for the infrastructure installation and maintenance.

The maintenance of all wiring including UPS, wireless, CATV and residential network services are
under the umbrella of Infrastructure Operations.

For any speci
al
requests to install wiring
which is outside our structural cabling standard for
unique

application requirements
;

theses must be submitted to Infrastructure Operations for review and
await approval before any installation can proceed.

1.2

Revision procedures

for this document

1.3

Review Committee

Any changes that are requested but do not comply with the standards layout within this document
will need to be presented to the review committee for approval. The committee consists of member
from the various teams within UIT.

Planning and Design

2.1

Communi
cation Rooms

2.1.1

Designated Space Requirements

The purpose of this room is to house all of the horizontal cables, the hardware, network switches,
backbone cablings, and protect the communications network from damage or interference. If a
communication room is
required for each floor within a building then they should be placed in the
same location of each floor to form a “vertical stacking” alignment.

Each building will have dedicated communication rooms that are dedicated for network and voice
communication ha
rdware.

The locations and size of the communication rooms will be determined based on the following
criteria:

1.

The distance from the communication room to the faceplate can not exceed 90
meters

2.

The determined cable path from the communication room to the t
erminating locations

3.

The vertical runways between floors

4.

Any physical architectural obstructions within the building.(i.e. glass walls, atriums,
open spaces)


7

5.

Secured, non shared space with other facilities.

6.

Amount of hardware to be installed into the space

to support services within a
building.

7.

Building footprint.

Each room is owned and operated by Infrastructure Operations

The minimum requirements for a room should be 3W x 4.8D x 2.4H meters.

2.2

Room Design Requirements


The communications rooms are not to b
e shared with other facilities such as electrical or HVAC
which can interfere or obstruct access or expansion of the communications equipment or interfere
with the operations of the equipment housed within the rooms.

Each room will have 4 10.16 centimeter

sleeves and are to be provided between vertically adjacent
rooms,

2.2.1

Room Shell/Walls/Floors/Ceiling

The ceiling will be sealed with dust retardant finish.


Each room will be sheeted in 1 centimeter thick plywood. The plywood
will be painted in fire
retardant paint. The plywood backboard sheets will be 2.4 Meters high and 1.2 Meters wide
and will support the weight of the cables and any other equipment that will be mounted.

8

Three walls within the room will be covered with the p
lywood and the fourth wall will be
furred out to accommodate the GIGA BIX.

The floor will be covered with anti
-
static retardant tiles. Floor loading will be rated in excess
of 68 kilograms (150lbs) per square foot.

Each room will have a building ground bus
s.

The wall switch should be placed on the inside of the entrance door.

2.2.2

Electrical/Power Supply

A main feed off of the main building breaker will be dedicated to an independent 100 amp
electrical panel within the communications room. This will service ON
LY the communication
room and or the stacking rooms.


Each wall will have at least two 120 VAC 20 amp receptacles

which will be mounted a
minimum of 15.24 centimeters from the finished floor, unless specified differently by
Infrastructure Operations

2.2.3

Cable
Trays

and Pathways

Horizontal cable pathways will be routed to avoid utilities or electrical interfe
rence. All
manufacturers, BICSI, and TIA installation codes will be strictly adhered to.



Cables trays are required in all comm. rooms



Tray minimum width is 45.72 centimeters wide.



Minimum of 30 centimeters of vertical space above the tray.



Provide clear
access to the top side of the tray at least every 5 meters



Minimum of 3 meters from floor level. Maximum of 6 meters from floor level, unless
building structure dictates otherwise.



Cable trays should service all areas where cable is required in the communi
cations
room: racks and planned rack spaces, Bix fields, cable entrance areas.


2.2.4

Lighting

Lighting will be suspended from the ceiling and will not interfere with the cable trays within
the room. Placement to be determined.


There should be provisioning for
emergency lighting in the event of a power interruption.

2.2.5

HVAC

Each communications room will have its own independent air conditioning which will be
operational 24/7 utilizing split units. The air climate will operate independently from seasonal
or off norm
al shut downs. Any campus wide work which affects the air quality of the
communications rooms must have a notification sent to the manager of the data centres and
Infrastructure Operations. The air temperature will remain constant 15C degrees and will no
i
ncrease above 22C degrees. Should this occur than notification through monitoring system
will inform Infrastructure Technicians to visit site and access situation.

Racks

The architectural design of the network racks is dependant on the type o
f switches that are
to be installed. There is a 10 year plan for each building that identifies the current network
switch installations, the projected 10 year growth and the planning of expansion of network
requirements which exceed the 10 year projections
.

Therefore for each network rack the placement of each switch, the naming convention for
each switch and the numbering of each switch is all considered and must be adhered to.

For example:

The labeling sequence will begin with C0001 for each communication room located within a
building.

For 10 year switch chasis architectural plans, space will be reserved on the gigabix to
correspond with the
placement of the chasis. Pigtails will also be installed at the time of the
build to correspond with the 10 year plan of the network switches.

Should the network requirements exceed the architectural network 10 year plan but
complete the full stack growth
the pigtail numbers will be reserved per chasis. Pigtails will
not be installed at this time. There will also be reserved space for the pigtails on the Gigabix,

Structured Cabling Design

4.1

Dual Star Topology Campus Configuration

The infrastructure consists of fibre optics, twisted pair and coax cabling systems which are set up
as a
star topology

with the Steacie Science Building being the control point for all services. The
infrastructure i
s situated throughout the university tunnel systems, building access systems and
between floors within buildings including the wiring to each end user/application. The Star Topology
is configured in a hierarchical format which permits no mores than two lev
els of cross connects.

York University has also implements a Dual Star Topology to ensure redundancy as well as
distribute network load activity evenly throughout the campus. Utilizing both sites to the best of their
operational abilities and taking advant
age of the hardware deployed at both control sites.

There are six major components of the
structured cabling system
.

This is a sample of the STAR TOPOLOGY Design for Keele Campus

Backbone Cabling

This term is used to describe cables that handle the major network traffic. It provides
interconnections between communication rooms, cable system structure. It consists of
backbone cables;
intermediate and main cross connects, mechanical terminations, patch
cords, and includes cabling between buildings.

The backbone cables consist of two types: interbuilding which supports traffic between
buildings and intrabuilding which support traffic wi
thin a building and between
communication rooms

4.6.1

Main (+IDF?) Cross Connect

The Main/Intermediate Cross Connect point is the main telecommunications centre and the
main data centre situated within Steacie. This is where the fibre and
copper cables are
picked up by the technicians of Infrastructure Operations and are then connected to a the
core network, switches and SL
-
100 hardware to begin the communication path between
York and all available services.

The backbone cables consist of t
wo types: interbuilding which supports traffic between
buildings and intrabuilding which support traffic within a building and between
communication rooms.

4.6.2

Interbuilding Cables

This consists of the cabling infrastructure pathways between the building and t
he entrance
from the service tunnel

4.7

Intermediate Cross Connects

The intermediate cross connects is the junction between the main communications room

4.8

Building Entrance Facility

The cabling components needed to provide a means to connect the Carrier Faciliti
es to the
building cabling. This is considered the point of demarcation when the owner (in this case York) is
handed over the ownership of the fiber.

4.8.1

Conduit

All exterior underground conduits used for the communication applications will be 10.16
centimete
rs EMA TC
-
6 type EB OVC plastic duct encased in concrete, As well the conduits
should be plugged to protect against environmental conditions, waste accumulation or
rodent access. All entrance conduits will be housed sparely from any electrical utilities.

There can not be more than two 90 degree manufactured bends within a 90 meter pull.


17

4.8.2

Drainage

The drain slope should not be less than 30 centimeters per every 30 meters.

4.8.3

Ducts

The communication rooms located closest to the service tunnel will have 4
-
10.16 c
entimeter ducts
to the service tunnel from the originating point. If the distance exceeds 59 meters from the
communications room and the service tunnel then provisioning for utility access will be required to
maintain cable pulls of less than 61 meters.

4.8.1

Ho
rizontal Cable Pathways

A horizontal pathways is a piece of the cable plant that feeds directly from a communication
room out to a users outlet or what we refer to as the
access layer.

Most commonly designed pathways consist of cable bundles that run from
the
communication room along J
-
hooks and or cable trays and or conduit. The cables are
suspended above a plenum ceiling and fan out once a work zone is reached. They are then
dropped through an interior wall inside conduits or support columns or raceways a
nd then
terminated at an information outlet (faceplate).

All conduits should be installed and properly numbered at both ends. If metallic than be
terminated with bushings. No section of conduit should exceed 30 meters or contain more
than two 90% bends. If

this is to exceed the 90 meters than a pull box should be placed.

4.9.2


Conduit Installation

The current diameter of a conduit should be no less than 1 inch for 8 s
tation wires.

Conduits should terminate on a separate electrical box and should be dedicated for the
communication cables and no other utilities are housed within these conduits. As well a poly
twine pull cord should be placed in each conduit.

Use of Contractors

The communications ca
bling contractor must be fully trained and experienced in the installations of
CAT 6 cable. The installer must be a certified approved on cabling systems. The contractor will
provide confirmation that all personnel assigned staff will be knowledgeable in t
he installation of
Category 6 UTP cables. Have project management experience. Have proof of WMIS training.

6.1

Satellite Sites/ Tenant Occupancy

Satellite Sites are sites in which York has a presence and is dependant on some or all of the
York services. An ex
ample of this would be York Gate Mall.

Tennant Occupancy is when York has a presence at a site but is not dependant on the York
network. The tenant uses their own network which does not integrate with York’s however
the technicians from Infrastructure
Operations continue to provide support for repairs or
cabling for renovations. Some locations would be 7271 Warden and the Nadal Centre
downtown.

These customers are reviewed on an individual basis. The delivery of services is dependant on
the circumstance

of the current tenant and space agreements.
