Follow the diagram in Figure 2-9 if you are performing a
postwire surface-mounted application or if you are using
apparatus boxes in a jack field.
The postwire surface-mounting requires a 104A
connecting Block. Two 4-pair modular cords coming
from the control unit (adjacent odd/even jacks) plug into it
and the voice pairs from each connect to the wires of a
single 4-pair modular cord. The voice terminal plugs
directly into the modular cord and then has the use of the
two voice pairs.
If you are using the Z122C apparatus boxes, you need to
provide two Z601A adapters for each terminal that
requires two voice-pairs. A single 4-pair cord can then be
run from the jack field to the voice terminal that requires
two voice-pairs.
