Do Not Disturb (DND)

System Availability: All systems

Station users with digital telephones can activate DND to prevent any calls from ringing their telephone. Callers will hear a fast busy tone when calling stations in the DND mode. Stations in DND mode can originate calls normally; however, they receive DND stutter dial tone (optional) when originating calls. With Release 1.3 and higher, users can disable DND stutter dial tone (1/2 sec. burst of busy tone before dial tone) in programming.

Call Forward-Busy will forward calls directed to a telephone with DND set, even if the telephone has idle [DNs]. Telephones with DND Override capability can ring DND telephones (see “Do Not Disturb (DND) Override” on page 146).
