Cables with more than 25
pairs
of wires are constructed from
25-pair groups Very

have
other variations
generally
not encountered inside terminal wire
plants
For
smaller
numbers
of
wires
such
as
wires for an individual

may
use
second color code scheme
Table
C-2
lists this
color
code and
the usual
correspondence
with
the paired-wire
color
code The
alternate
color
code
is
included
because sometimes
the
station
wire
uses the
first
three
pairs
of the standard color
code
white-blue
blue-white
and
so
on
and
other
times
it
uses the
six alternate
colored
wires
