The DSS, shown in Figure 7, has an array of 50 buttons, called DSS buttons,
with red LEDs. A maximum of two DSSs can be connected together 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 left-most) is the
Message Status button, which is used to change to and from Message Status
operation. When you are in Message Status state, 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 ten buttons at the bottom of
the second DSS are not operable (reserved for future use).

A page is the range of extension numbers that is assigned to a DSS. A single
DSS can have three pages of extension numbers, with 50 extension numbers
per page, for a total of 150 extension numbers. When two DSS are connected,
each page’s capacity is increased to 100 extension numbers. The two
connected DSS can have three pages of extension numbers for a total of 300
extension numbers.
