THINGS YOU SHOULD KNOW
USER ORIENTATION
DS 24D/DS 24S telephones are called “keysets.” They contain buttons or
“keys” that are used to access or activate the many features of your office
phone system. The keys with paper designation strips are programmable
keys. This means they can be programmed for a specific function on your
keyset and that same button can be something different on another keyset.
See the system manager to get your most frequently used features assigned
to your programmable keys. When changes are made, be sure that your pro-
grammable keys are relabeled properly.
Lines from the telephone company are “C.O. lines.” Calls on these lines are
referred to as “outside calls.” Your system can have individual C.O. line keys
or lines may be assigned to groups. When they are in a group, you access
a line by dialling an access code or pressing a route button. For example,
dial 0 or press a “LOCAL” key to get a local outside line. If Least Cost Routing
is used, pressing the “LCR” key will automatically select a preprogrammed
C.O. line according to what digits are dialled. Each line in the system is
numbered, beginning with 701, then 702, 703, etc.
Direct Station Selection (DSS) keys are programmed to ring specific sta-
tions. You can press a DSS key instead of dialling the extension number. A
DSS key lights red when that station is busy (Busy Lamp Indication).
DS 24D/DS 24S keysets provide distinctive ring patterns:
•
Outside calls have a double ring tone repeated.
•
Internal calls have a single ring tone repeated.
•
Door phone calls and alarm/appointment reminders have a short ring
tone repeated very quickly.
CALL INDICATIONS
The keys on your phone have light emitting diodes (LEDs). These are tri-col-
oured LEDs that light green, red or amber (green and red together).
Intercom calls, also called internal calls, always appear on your CALL but-
tons. They will always light green. You can have up to four CALL buttons, but
at least two are recommended.
Outside calls appear on individual line keys if they are assigned. When an
individual line is not assigned to its own key, it will appear on a CALL button.
