Total Unit Load for Slots 5 and 6

†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.
