† 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.
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.
