Description

General

This Standard specifies the requirements for a uniform
telecommunications grounding and bonding
infrastructure that shall be followed within commercial buildings
where telecommunications
equipment will be installed.

This Standard specifies a telecommunications grounding and bonding
infrastructure and its
interconnection to other building systems.

Figure 2.1-1 depicts the scope of the telecommunications grounding and
bonding infrastructure for
larger, multi-story commercial buildings with multiple
telecommunications backbones. Figure 2.1-2
depicts a smaller commercial building where telecommunications spaces
are combined. This Standard
specifies the requirements for:

– A ground (earth) reference for telecommunications systems within the
telecommunications entrance
facility, the telecommunications room, and equipment room;

– Bonding of metallic pathways, cable shields, conductors, and
hardware at telecommunications
rooms, equipment rooms, and entrance facilities.

This Standard is intended to encourage planning, which should include
grounding and bonding
arrangements to accommodate telecommunications equipment installation.

While primarily intended to provide direction for design of new
commercial buildings, this Standard
may be used as a guide for the renovation or retrofit of existing
buildings.

Design requirements and choices are described to enable the designer
to make informed design
decisions.

Exclusions from this Standard

a) Specific grounding and bonding of any telecommunications equipment
and associated wiring;

b) Values of surge current immunity and insulation withstand voltages;

c) Methods for verifying and maintaining grounding and bonding
networks;

d) Specific methods for RFI/EMI mitigation for equipment or systems;

e) Primary protector/arrester specifications, applications and
installation;

f) Secondary protector specifications and applications;

g) Specific user safety;

h) Grounding and bonding practices of the local telecommunications
utilities;

i) Electrical service entrance;
