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 MXL-28D or MLX-20L) 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 unit load for slots 5 and 6 is less than or equal to 27, auxiliary
power is sufficient for the carrier.
■ If the unit load for slots 5 and 6 is more than 27, continue to Step 9.
