Light Pattern
Flashing red A corresponding SDN extension is holding
slowly a call.
Flashing red The PDN extension is receiving an
rapidly incoming call to an incoming call
distribution (ICD) group.
SDN Direct Dial
Using an SDN button, you can easily call the corresponding PDN extension. SDN buttons are in one of two
modes depending on system programming, and the operation procedure differs as follows:
Enhanced DSS Key Mode
PT/PS
Off-hook.
Standard SDN Key Mode
PT/PS
Off-hook.
•
When performing SDN Direct Dial to call the corresponding PDN extension, the SDN button
light shows the current status of the destination extension as follows:
Green on: You are using the line.
Red on: The line is being used. (The PDN extension, or another SDN extension when
multiple extensions have SDN buttons to a same PDN extension, is using the line.)
•
Even if a PDN extension has set Do Not Disturb (DND), you can call the extension as
normal by pressing the SDN button.
•
When an SDN button is in Standard SDN Key Mode, you can dial a telephone number while
hearing a dial tone, instead of pressing the SDN button again. Depending on system
programming, your call will be made using either your normal calling privileges (Class of
Service) or those of the corresponding PDN extension (SDN Walking COS).
Call Hold and Call Hold Retrieve
You can put calls answered with a PDN or SDN button on hold normally (→1.4.2 Holding a Call).
