6. Using Additional Features
DN may be assigned to keys on a telephone. This allows calls to the DN to appear
on multiple telephones. The calls ring in on a specified basis - immediate, delayed,
or no-ring.
A telephone may only have one PDN (on up to three keys) but may have multiple
NPDNs with up to three appearances of any one NPDN.
Figure 19. 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 EXT 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 EXT 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.
