Page 1336 of 3156 Distinctive Ringing by DN
553-3001-306 Standard 10.00 January 2002
A sub prompt for every DN key configures distinctive ringing index for
incoming and outgoing calls. There are two available features for incoming
and outgoing calls:
• Distinctive Ringing by call source, per DN-key: The distinctive
ringing given to the called set is determined by the call source (calling
set). This functionality is the same as the EDRG feature, except it is DN-
key based rather than set based
• Distinctive Ringing by call destination, per DN-key: The distinctive
ringing given to the called set is determined by the call destination (called
set) and is also based on the DN-key of the called set.
With these enhancements, a DN-key can be configured to give a distinctive
ring to the terminating set, and receive a distinctive ring for incoming calls.
Operating parameters
The precedence order for the different distinctive ringing cadences to ring the
terminating set in a call is:
• Distinctive Ringing for an Incoming trunk call
• Distinctive Ringing by DN by call source
• Executive Ringing by DN call destination
• Distinctive Ringing by DN by call destination
The Private Line Ringing (PVR)/ Non-Ringing (PVN) keys are not supported
by the DRDN features.
No DRDN functionality is supported on the Voice Call (VCC) keys since no
DN is assigned to a VCC key.
The QPC609D Fast Tone and Digit Switch card, or a later version of this card,
is required to implement the New Distinctive Ringing feature.
A total of five distinctive ringing cadences used by DRDN are supported.
Therefore a set with more than five DNs will have at least two DN-keys with
the same distinctive ringing cadences.
