Requirements
The selector console is connected to the attendant console by a 3-foot
D8AC cord that is furnished with the selector console (Figure 4-17).
Note: When a basic attendant console, equipped with a selector
console, is powered by a 346A power unit, the slide switch on the
power unit must be set to the up position. This provides 20 watts
of power to the jack located above the slide switch. The console
must be connected to this jack.

attendant console and modular jack on bottom of selector console.
