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 (® 10.1.2 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 (®
20.1.2 Walking Extension).
•
Wireless XDP Parallel Mode
If a PS has PDN or SDN buttons, Wireless XDP Parallel mode cannot be assigned to that PS (®
20.1.5 Wireless XDP Parallel Mode).
•
OHCA/Whisper OHCA
A PDN extension cannot receive OHCA or Whisper OHCA, unless the call is made using a corresponding
SDN button (® 12.1.3 OHCA (Off-hook Call Announcement), ® 20.1.4 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 (®
9.1.13 Intercom Call).
[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.
