Distinctive Ringing
Distinctive Ringing provides several ringing cycles to help telephone users and
attendants distinguish between incoming call types. Administer Distinctive
Audible Alerting on Feature-Related Syst em Parameters for internal, external,
priority, and attendant originated calls.
If the phone is a single-line analog, you have to set this on the Station screen for
each user.
Detailed description
You can administer system-wide distinctive-ringing cycles for the three basic call
types. Most installations use 1-burst for internal calls, 2-burst for external calls,
and 3-burst for priority calls. There are also non-administrable ringing signals for
Automatic and Dial Intercom calls, Manual Signaling, and Redirect Notification.
Normally if an internal phone user transfers an external call, the call rings as
internal. You can set a feature parameter (Update Transferred Ringing Pattern) to
make the call ring as an external call.
Considerations
■If Distinctive Ringing is disabled, the system gen erates a 1-burst repetitive
tone for all incoming calls. This is useful for equipment interfaced by
analog lines, especially if you use off-premises station.
■A single distinctive ring cycle is used for each new incom ing call to an
off-hook telephone or headset. The system alerts a CALLMASTER
terminal with a single ring cycle whenever eithe r the heads et or the h andset
is plugged into the headset jack.
Interactions
■Personalized Ringing
The called party hears the user-selected ringing pattern for the distinctive
ring cycles.

stream. DS1 can be used for voice or voice-grade data and for data-transmission
