AT&T 518-600-016 manual Wiring the System

Follow the diagram in Figure 2-9if 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.
