Total Actual Unit Load
†
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 three-carrier system can have six
system operator positions, each with one DSS powered from the control unit.
■ If the total actual unit load is less than or equal to 54, auxiliary power is
not required.
■ If the total actual unit load is greater than 54, continue to Step 7.
