Distinctive Ringing
Distinctive Ringing
Description
This feature allows users to distinguish between different types of incoming calls. The
system provides the following types of ringing:
● A repeated two-burst tone indicates an outside call or a call extended by the
attendant. The two-burst tone pattern is: 0.4 seconds on, 0.2 seconds off, 0.6
seconds on, and 4.0 seconds off.
● A repeated one-burst pattern indicates a call from an internal user. The tone is one
second on and three seconds off for multiline voice terminals, and 1.2 seconds on
and 4 seconds off for single-line voice terminals.
● A “abbreviated alerting” signal (also called single-ring reminder) indicates to the off-
hook user of a multiline voice terminal that a new call is coming into another call
appearance button. This type of call rings just once, but the associated status LED
continues to flash after the abbreviated alerting stops. The user may place the
current call on hold and answer the incoming call if desired.
● A single short beep at a voice terminal equipped with the Hands-Free Answer feature
indicates that an incoming inside call has been answered by the terminal. Depending
on the status of the terminal’s HFAI controls, the user can talk with the caller without
lifting the handset.
● Priority ringing is a repeated pattern of two short rings followed by one long ring. It
indicates (1) that a data terminal has used the Third-Party Call Setup feature to
originate a voice call from the voice terminal where this ringing is heard, or (2) that a
queued-for facility is now available and the user can go off hook for the call to be
completed.
