Adjunct Power Units
Adjunct Power Units
General
There are two types of power supplies used for adjunct powering,
individual and bulk. The power supplies are specified by the Field
Services Organization (FSO) for firm quote price lists. For all other
quotes, the power supplies are specified by the PSC.
Individual Power Supplies
Individual power supplies (Figure 2-23) can be used for powering from
the equipment room, site or satellite locations, or information outlets.
An individual power supply can power only one voice terminal. Table
2-D contains the individual power supply limitations for distance, wire
gauge, and adjuncts.
