Direct Station Select (DSS)
Direct Station Select (DSS) lets you monitor and
automatically dial or answer an extension. The status
light next to the DSS (D-) key on your telephone indi-
cates whether that extension is idle, ringing, or busy.
Whenever someone is calling that extension, the
status light next to the DSS key on your telephone
blinks. Your telephone may also alert you to such a
call with a single beep, if it has been set up at the CBX
to do this. When a call is in progress on the DSS
extension, the status light turns on steadily.
When the DSS key status light is off, you can dial the
DSS extension by pressing the DSS key. When the
DSS key status light is blinking, you can answer a call
ringing at the DSS extension by pressing the DSS key.
When the DSS key status light is on, pressing the DSS
key will place a call to the busy extension. This call
will automatically queue until the station becomes
available. (See “Busy Standby Queuing” on page
3–6.) Before you can use this feature, you must set up
an extension to be associated with your DSS key.
