THINGS YOU SHOULD KNOW
USER ORIENTATION
The DS Series keysets incorporate buttons or “keys” that are used to access or acti-
vate the many features of your office phone system. The DS 5021D keysets incor-
porate 21 programmable buttons. These 21 buttons are arranged in three rows of
seven across the face of the keyset. Any of the system features or functions can be
programmed to these buttons.
The three buttons above the top row of programmable buttons are soft keys.
These buttons assist in the use of the system features and functions.
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 dialing an
access code or pressing a route button. For example, dial 9 or press a “LOCAL” but-
ton to get a local outside line. If Least Cost Routing is used, pressing the “LCR” but-
ton will automatically select a preprogrammed C.O. line according to what digits
are dialed. Each line in the system is numbered, beginning with 701, then 702, 703,
etc.
Direct Station Selection (DSS) buttons are programmed to ring specific stations.
You can press a DSS button instead of dialing the extension number.
CALL INDICATIONS
The buttons on your phone have light emitting diodes (LEDs).These are tri-colored
LEDs that light green, red or amber (green and red together).
Intercom calls, also called internal calls, always appear on your CALL buttons. They
will always light green.You can have up to eight CALL buttons, but at least two are
recommended.
Outside calls appear on individual line buttons if they are assigned. When an indi-
vidual line is not assigned to its own button, it will appear on a CALL button.
Your outside calls will light green on your keyset and red on other keysets. You
never lose sight of your calls while they are on hold. They stay right where you put
them and are identified with a green flashing light.
