† The MFM has its own individual 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 unit load for slots five and six is less than or equal to 27,
auxiliary power is sufficient for the carrier.
If the unit load for slots five and six is more than 27, continue to
Step 9.
