Feature Reference
Message-waiting LED status
Operator park zones
The DSS, shown in Figure 13, has an array of 50 buttons, called DSS buttons ,
with red LEDs. A maximum of two DSSs can be connected to provide a field of
100 buttons. Ten additional fixed-feature buttons with green LEDs are at the
bottom of the DSS. The first three (from left to right) on the top row are Page
buttons, which are used to select the range of extension numbers represented
by the DSS buttons. A fourth button (lower leftmost) is the Message Status
button, which is used to turn message status operation on and off. When you
are using the Message Status feature, the LED next to each DSS button
indicates whether or not a message is waiting from a system operator. The
remaining six buttons on the first DSS and the 10 buttons at the bottom of the
second DSS are not operable (reserved for future use), except on a QCC, where
the right-most button on the second to last row of the first DSS activates the
Direct Voice Mail feature.
