Unit Load Calculation
Page F-7Unit Load Worksheet
F
* Unit loads are computed for each trunk for trunk-type network access lines.
† 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 for each MLX-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.
