KS22911 — A power supply that plugs into three-prong 120 VAC outlets at the workstation. The

KS22911 supplies -48 VDC up to 150 ft for any one adjunct and a speakerphone or headset. When
the KS22911 is used at the workstation, it provides power through the connecting cord to a terminal.

When small numbers of terminals require adjunct power, the KS22911 power supply can be installed
in the satellite closet. From the satellite closet it provides power over the fourth pair of the 4-pair
installation cable, to the information out.let (IO) at the workstation.  If the distance from the satellite
closet to the workstation exceeds 150 ft. you must install the power supply at the workstation.

The 346A modular bulk power unit is installed only in the satellite closet and accepts up to three 346A
power supplies. Each 346A has four outputs. The power unit plugs into a standard 120 VAC outlet

with 20A service. As many as four power units can be connected to the same 20A circuit, which must

be dedicated and unswitched.

Each pair of outputs on the 346A has a slide switch between them. The switch allows the outputs to

operate individually and supply 10W of power, or to operate in combination and put out 20W of power.
The 346A transmit power over the fourth pair of the cable that connect the intermediate distribution field

(IDF) to the IO at the workstation.

When the outputs on the 346As are operating individually (10W), they can power one speakerphone or
headset and one other adjunct. When two outlets are operated in combination (20W power comes only

from the upper output; the lower one is without power), they can power a data module, two other
adjuncts and a speakerphone or headset attached to one voice terminal. Table 12-1, Maximum Loop

Lengths for the 346A Power Unit, shows the loop distance for the 346A power unit.
