* 
Unit loads are computed per trunk for trunk-type network
access lines.
† Up to two DSS consoles (one DSS per MLX-28D or MLX-20L)
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.
‡ The MFM is powered by an individual wall power unit located
at the station.
