Appendix B - Tones
Tones are audible signals of various frequencies that give information about the status of calls and features. While
using the Coral system, many different tones will be heard. These tones may vary for different locations, as each
system is customized during installation. While the sounds of the tones themselves are not described, their general use
is discussed below. In order to familiarize yourself with these tones, try accessing various features and listen to the
resultant tone signals. The most frequently heard tones are:
Break-In/Break-Out Tone
A warning tone received by a station user indicating that a third party has broken into, or
is leaving (breaking out) an existing conversation.
Break-In Warning
Tone heard during the entire break-in period. Indicates that a third party is listening (not
used in North America)
Busy Tone
Tone heard when the destination you have dialed (extension or trunk) is busy.
Call Waiting Tone
Tone heard at your FlexSet station while engaged on a call or activating a feature
indicating that another call is waiting to be answered (this appears only when multi-
appearance is defined for your FlexSet station).
Confirmation Tone
Tone heard indicating that the telephony feature has been activated or deactivated.
Dial Tone
Tone heard after off-hooking (lifting) your handset from idle.
