	Unit Load Calculation

A unit load is a measure of power (1.9 watts) used to determine the electrical load that the following components have on each carrier’s power supply:

■Telephones and Adjuncts. Only the telephones and adjuncts that connect to the analog and digital ports on the control unit require unit load calculation. Do not include any equipment with its own power supply in the unit load calculation.

■Direct Inward Dial (DID) modules

Unit load and power requirements for a new system are computed automatically when the equipment for the system is initially ordered. These calculations are based on the assumption that each module is fully utilized, that is, all jacks are used.

It may be useful to obtain more accurate calculations, for example, if the modules are not fully utilized, if there is a change in the equipment, or if you suspect that a particular carrier has more unit loads than the power supply can handle. You can calculate the actual unit load using the worksheet and instructions in this appendix.
