Direct Station Selector
The Direct Station Selector (DSS), shown in Figure 3–9, is an adjunct that you
can connect to an MLX-20L or an MLX-28D telephone programmed as an
operator console (it cannot connect to any other telephone). DSSs enhance the
capabilities of both DLCs and QCCs and, when connected to an MLX-20L
telephone, help with programming. The DSS has 50 multifunction buttons, all of
which have lights.
