1.3.49 PDN (Primary Directory Number)/SDN (Secondary Directory Number) Extension • 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.
