Do Not Disturb (DND)
If your station is in the DND mode, internal, external and transferred calls do not ring your
station and OCA calls are denied. You can continue to make calls while in the DND mode.
If your [PDN] or [PhDN] appears on other stations, the calls flash on your station and flash or
ring the other stations. Other stations can answer your calls or you can, even while your station
is in the DND mode.
Your “alert partner” telephone can override your DND and signal your telephone by pressing
