New Distinctive Ringing
This feature provides a new ringing cadence of 0.512 on and 0.512 off,
followed by 1.024 on and 4.096 off, for all telephone types.
Distinctive Ringing for Dial Intercom
This feature allows a user to differentiate between an incoming call and a Dial
Intercom call. The Dial Intercom ringing has a different cadence than regular
Directory Number (DN) ringing or Distinctive Ringing.
Distinctive Ringing for Dial Intercom is assignable on a per-customer basis.
The cadence is 0.5 on and 0.5 off, repeatedly.
Operating parameters
Distinctive Ringing requires 2.5 times as much “on” ringing time as routine
ringing. The number of simultaneously ringing lines per ringing generator is
reduced according to the proportion of incoming calls that receive Distinctive
Ringing. For example, if 50 percent of all calls receive Distinctive Ringing,
the number of simultaneous ringing lines is reduced from 20 to 14 per ringing
generator.
The QPC609D Fast Tone and Digit Switch card, or a later version of this card,
is required to implement the New Distinctive Ringing feature.
Feature interactions

they terminate on the Attendant Console.
Call Forward No Answer, Second Level
The ringing cadence for all telephones in a chain of call redirections remains
the same as for the original DN called.
