Through system programming, it is possible for only incoming calls arriving at PDN buttons to be answered
simply by going off-hook, by selecting
"PDN" as the incoming line preference (® 12.1.2 Line
Preference—Incoming). This prohibits calls that arrive on non-PDN buttons (e.g., an SDN button) to be
answered when going off-hook.
• Walking Extension
For PDN extensions, the Walking Extension feature can only be used when all PDN buttons are idle (®
22.1.2 Walking Extension).
• Wireless XDP Parallel Mode
If a PS has PDN or SDN buttons, Wireless XDP Parallel mode cannot be assigned to that PS (®
22.1.6 Wireless XDP Parallel Mode).
• One numbered extension
If an extension has PDN or SDN buttons, Sub extension of One numbered extension cannot be assigned
to that extension (® 14.1.7 One-numbered Extension).
• OHCA/Whisper OHCA
A PDN extension cannot receive OHCA or Whisper OHCA, unless the call is made using a corresponding
SDN button (® 14.1.3 OHCA (Off-hook Call Announcement), ® 22.1.5 Whisper OHCA).
• Alternate Calling—Ring/Voice
It is not possible to temporarily change the called party’s preset call receiving method (ring tone or voice)
when calling a PDN extension, unless the call is made using a corresponding SDN button
(® 10.1.14 Intercom Call).
• Through system programming, it is possible to force an extension to become idle (the SP-PHONE button
light will turn off) when a speakerphone call using a PDN/SDN button is put on hold using CTI.
[Delayed Ringing]
• The same delayed ringing setting is applied to all PDN buttons on an extension. Delayed ringing can be
assigned separately for each SDN button.
• Through system programming, it is possible to select whether caller information (such as Caller ID) is
shown immediately on a PS when a call is received while delayed ringing is set.
• Caller information (such as Caller ID) is not shown immediately on a PT when a call is received while
delayed ringing is set.
• SDN buttons can be set to not ring (only flash) for incoming calls. However, this setting is not available for
PDN buttons.
• The forward no answer timer starts when a PDN extension starts ringing.
