DSS 4450
Understanding Your DSS
2
Message Status Button
When Message Status is on, the red lights next
to the DSS buttons turn on for extensions with
messages from system operators. Messages
from other sources (such as co-workers and fax
machines) do not cause the red lights to turn on.
The green light next to the Message Status
button turns on when the button is pressed to
tell you that the lights on the DSS are showing
Message Status. Pressing the button again turns
off Message Status and the green light.
DSS Buttons
Each DSS has 50 DSS buttons, arranged in 5 columns of 10 buttons
each. DSS buttons have numbers assigned in consecutive order, start-
ing with the top left corner button. Each button can have 3 numbers as-
signed to it, which can correspond to the following:
• Extension numbers for directing or making calls to co-workers
(see pp. 10–11).
• Paging numbers for paging co-workers over speakerphones or a
loudspeaker system (see p. 25).
• Numbers for parking calls to the system operator Park Zones
(see p. 25).
• Pools and lines for monitoring the pools’ current status.
Fixed Page Buttons
Press the fixed Page buttons to change the page
of telephone numbers accessible to your DSS.
The green light turns on next to the Page button
that is active. If you have one DSS, Page 1
accesses the first 50 extensions, Page 2
accesses the second 50 extensions, and Page 3
accesses the third 50 extensions. If you have
two DSSs, Page 1 accesses the first 100
extensions, Page 2 accesses the second 100
extensions, and Page 3 accesses the third 100
extensions.
