General Information
2-10Voice Terminals
2
■ Lighted steadily—the call appearance is busy or the assigned feature is
active.
■ Flashing (slow on-off for equal periods, one cycle per second)—an
unanswered incoming call on that call appearance.
■ Fluttering (fast on-off for equal periods, 10 cycles per second)—a call
placed on hold on that call appearance by the voice terminal user.
■ Broken Fluttering (fast on-off modulated at the slow rate)—feature denial to
the calling voice terminal or an unknown or invalid action.
■ Winking (long on-short off at about three cycles per second)—a call placed
on hold from another voice terminal or an action pending.
Message Light
The Message light, when on, indicates that a message is waiting for the voice
terminal’s user (for example, Leave Word Calling or voice mail messages). When
the user retrieves the message, the light is automatically turned off.
Tones
The tones that a voice terminal user hears can be divided into two categories:
■ Ringing Tones—those that are generated in the base of the voice terminal
and can be heard in the surrounding area; they indicate incoming calls.
■ Handset Tones—those that are transmitted through the handset and heard
only by the user or through the speakerphone when it is turned on.
External Ringing Tones
Ringing tones are the only tones heard
outside the voice terminal
when it is
receiving a call. This signal cycles in 1-, 2-, or 3-ring patterns. On System 75 and
DEFINITY G1 and G3, only one cycle of ringing is heard if the multi-appearance
voice terminal is busy with another call. On System 85 and DEFINITY G2, the
cycling repeats (except on the ISDN 7500-series sets).
■ One ring—a call from another voice terminal in the system
■ Two rings—a call from the attendant or outside caller
■ Three rings—priority calls, for example, Automatic Callback, Priority
Calling, or Ringback from a queued call
■ One short unmodulated tone—an intercom call
■ Ring-Ping (half ring)—a call redirected away from the voice terminal
because Send All Calls or Call Forwarding is active; also called coverage
tone.
■ On System 85 and DEFINITY G2, any of these external tones, plus a
repeated unmodulated tone, may be administered to indicate an intercom
call.
