Figure 3. Example Directory Number assignments for Extension 200
When a caller originates a call, the call appears on the first available PDN key. If all PDNs are
unavailable, the call will select the INT LED.
When calls come in to a DN, the call appears on the first available DN key. If the call is to your PDN
and no PDN key is available, the call appears on the INT LED.
Directory numbers may be assigned to FF keys 25-32. These are non-appearing keys.
Intercom voice calls only go to the PDN extension but light the corresponding NPDN keys red. A tone
call follows the appropriate ring status (immediate ring, delayed ring, etc.) for any extension.
To originate a call using a Primary Directory Number:
1. Lift the handset or press the ON/OFF key.
2. If dialling an outside call, dial the outside line group access
code (default = 9 [UK/HK], 0 [Taiwan, Malaysia, Indone-
sia], or 81-84).
3. Dial the phone number or extension number.
To receive a call to a Directory Number (PDN or NPDN):
1. If ringing, go off-hook or press the green blinking PDN or
NPDN key.
If not ringing, press the red blinking PDN or NPDN key.
