Panasonic KX-NCP500 - 3.2 Manager Programming

For example, if a PDN extension receives an incoming call while on a call, the LEDs on the corresponding
SDN extensions will show the incoming call.
However, if an SDN
extension is handling a call using the SDN button (e.g., on a call, has a call on hold, etc.),
the status of that call will be displayed on the SDN button, regardless of the call status of the PDN extension.
Example of a Secretary Handling Calls for Multiple Bosses
The following example shows the LED patterns of the PDN and SDN buttons of each extension and how calls
can be handled.
