If an incoming trunk call rings unanswered for a (programmable) period of time, the call's ringing
pattern and dB level changes automatically so users can tell which calls have been ringing
longer. You can program the pattern of the ringing. You can also enable this feature on some
trunks, and disable it on others.

• Users can distinguish between calls that have been ringing longer than others.

If a user is on a phone call for a long time, an alarm tone sounds intermittently in the handset
receiver. This feature can be turned on/off system-wide in programming. If you turn it on, you can
also enable/disable individual phones and trunks for it, as well as programming the amount of
time before the alarm goes off.

• The DBS 576 can automatically monitor call duration, and let users know when
they've been on a phone call too long.
   !
If a user places an outside phone call and gets a busy tone, he/she can stay on the line and
press REDIAL. The DBS 576 will automatically send a Flash signal, redial the call, and wait to
detect busy tone on the line (note: this doesn't work on E&M tie-lines or ground-start trunks). If
the line is still busy, the system will try again and again, at programmable intervals, until one of
the following happens (whichever occurs first): 1) the called party answers; 2) the user hangs up;
or 3) the system tries 14 more times.
You can turn this feature on/off for individual extensions, and also enable/disable it on individual
trunks. You can also program the amount of time the system waits to detect busy or answer, as
well as the interval between redial attempts.

• An automatic feature that helps phone users save time and reduce dialing errors.

Users can set their phones to play Background Music on-speaker while the phone is idle. If the
phone receives a call, or the user goes off-hook, BGM will go away until the phone becomes idle
