Distinctive LED Indicator

System Availability: All systems

Each feature button on a digital telephone has a Light Emitting Diode (LED) indicator. Distinctive LED indicators provide a method for quickly identifying the status of a line or feature button. The LED color or flash pattern can identify the call you are currently on, as well as other calls you are controlling, versus other calls that may appear on your telephone. Each telephone uses dual-color LEDs: green for lines you are using; red for lines used by someone else.
