1.7 Primary Directory Number (PDN)/Secondary Directory Number (SDN) Features
• When a PDN extension is a member of an ICD group in Ring Distribution method, and an incoming call
arrives at the ICD group, the incoming call status will not appear on the LEDs of the corresponding SDN
extensions (→ 1.2.2.1 Incoming Call Distribution Group Features—SUMMARY).
• If none of an extension's PDN buttons are idle, DSS buttons of other extensions registered to the PDN
extension will turn on red.
• Ring Tone Pattern
Through system programming, each extension can set ring tone patterns for PDN buttons. Ring tone
patterns can be assigned separately for each SDN button.
• Outgoing Line Preference
When "PDN" is selected as the outgoing line preference, outgoing calls will originate on the first
available PDN button (→ 1.5.5.2 Line Preference—Outgoing).
• Incoming Line Preference
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 (→ 1.4.1.2 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 (→
1.28.3 Walking Extension).
• Wireless XDP Parallel Mode
If a PS has PDN or SDN buttons, Wireless XDP Parallel mode cannot be assigned to that PS (→ 1.25.5
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 (→ 1.8.4.3 Off-hook Call Announcement (OHCA), → 1.8.4.4 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 (→
1.5.3 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.
• 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.
