The keys with paper designation strips are programmable keys. Thismeans they can be programmed for a specific function on your keyset andthat same button can be something different on another keyset. See the sys-tem manager to get your most frequently used features assigned to yourprogrammable keys. When changes are made, be sure that your program-mable keys are relabeled properly.Lines from the telephone company are “C.O. lines.” Calls on these lines arereferred to as “outside calls.” Your system can have individual C.O. line keysor lines may be assigned to groups. When they are in a group, you accessa line by dialing an access code or pressing a route button. For example, dial9 or press a “LOCAL” key to get a local outside line. If Least Cost Routing isused, pressing the “LCR” key will automatically select a preprogrammedC.O. line according to what digits are dialed. Each line in the system is num-bered, 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 dialing the extension number. ADSS key lights red when that station is busy (Busy Lamp Indication).iDCS keysets provide distinctive ring patterns:• Outside calls have a single ring tone repeated.• Internal calls have a double ring tone repeated.• Door phone calls and alarm/appointment reminders have a triple ringtone repeated.CALL INDICATIONSThe keys on your phone have light emitting diodes (LEDs). These are tri-col-ored 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 eight CALL buttons,but at least two are recommended.Outside calls appear on individual line keys if they are assigned. When anindividual line is not assigned to its own key, it will appear on a CALL button.
