Wearing
a
heart
pacemaker?
Don't
attempt
to
install,
fix
or
modify
any
telephone
wiring.
You
are
at
risk.
An
electrical
storm?
By
all
means
avoid
doing
any
telephone
wiring
work
during
electrical
storms.
Stop
all
ongoing
work.
Avoid
bending
cable
sharply
or
nick
the
protective
jacket
over
the
inside
wires
and
never
run
phone
cables
in
parallel
with
power
cables
either.
When
performing
cable
runs,
avoid
at
all
costs
pulling
too
hard
(more
than
25
pounds
by
standard)
over
the
phone
cables.
This
might
damage
the
inner
wires.
Avoid
splicing
individual
wires
on
the
cable
runs.
If
any
wire
turns
out
to
be
defective,
replace
the
entire
cable.
It
is
preferable
to
use
daisy-chaining
to
the
closest
phone
termination
than
splicing,
if
complete
replacement
of
the
cable
is
absolutely
not
an
option.
It
is
even
worse
to
bury
a
spliced
cable
within
the
wall
during
rough-in
in
a
new
or
remodeling
construction
job.
When
running
cables
over
flat
surfaces
and
supporting
them
with
staples,
avoid
driving
staples
in
too
tightly,
for
insulation
damage
may
result
to
the
inner
wires.
This
will
irreparably
damage
the
performance
level
of
the
cable,
if
not
impairing
the
cable
outright.
Running
phone
cables
under
carpet
is
not
a
good
practice.
The
cable
will
be
damaged
rather
sooner
that
later
if
the
area
is
expected
to
be
a
transited
area.
Every
connection
in
a
wiring
system,
whether
good
or
poor,
degrades
overall
performance
of
premise
equipments.
So
use
the
strict
necessary
minimum.
If
any
segment
of
your
wiring
system
develops
low
performance,
premise
equipments
are
most
likely
to
perform
to
the
quality
level
allowed
by
that
segment,
however
the
optimum
quality
of
the
rest
of
the
installation.
Therefore
never
install
dubious
components,
or
components
of
unknown
or
questionable
origin.
In
telephone
wiring,
excess
capacity
in
terms
of
number
of
available
segments
is
better
than
not
enough.
Scarcity
translates
into
higher
expansion
costs
down
the
road.
