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.
