Free conductors length (each cable) = 2 X splice opening plus 6" (152 mm)
26" (66 cm) minimum
6.7.2 Identify all binder groups. Starting with lower
back groups, tightly tie matching groups togeth-
er as close to cable butt as possible.
For easy group ID, foldback odd number
groups to left side and even number groups
to the right.

6.7.5 Splice first group, identify and bundle to the
core.

6.7.8 Splice third group.
Note:
When making three bank foldback splices,
bundle while splicing. Splice a 100-pair
group in one position, bundle to core;
repeat procedure in another position and
fit modules into vacant locations. Splice
so that approximately an equal number of
modules fall in each of the three positions.
6.7.7 Splice second group, identify and bundle to the
core.
