Unit Load Calculation Worksheet

Unit Load Worksheet
■ If the total actual unit load is less than or equal to 54, any power supply
module is sufficient.
■ If the total actual unit load is greater than 54, continue to Step 7.
* The MFM has its own wall power unit located at the telephone and therefore is
not added to the unit load calculation.
† Up to two DSSs (one DSS per MLX-28D or MLX-20L console) can be powered
from each control unit carrier. For example, a 3-carrier system can have 6
system operator positions, each with one DSS powered from the control unit.
