Page 1338 of 3156 Distinctive Ringing by DN
553-3001-306 Standard 10.00 January 2002
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. When CFNA is activated for a set,
distinctive ringing is given to the called set if the originator set is configured
with DRDN, otherwise normal ringing is given.
Call Transfer
The ringing of the redirected call is determined by the set that has originated
the call and not by the set transferring the call. The transferred call
distinctively rings the called set if the originating set is configured with
DRDN. If the originating set is not configured with DRDN then the ringing
of the transferred call is determined by the called set.
Conference
The conference call is either scanned for a call marked as distinctive or a set
designed as an executive set. The conferee with the highest index determines
the ringing for the new call. The index of the conferees across the network
checks if the network supports NAS supplementary messaging.
Dial Intercom Call
A Dial Intercom call is distinguished from a normal call since it has a
different cadence configured in the FTC table. Dial Intercom takes
precedence over the existing EDRG feature.
Distinctive Ringing
Existing Distinctive Ringing by DN (defined by the Class of Service in
LD 11) specifies the frequency and the tone rate where the DRDN features
supports the cadences.
Distinctive Ringing by an Incoming Trunk Call
All calling sets marked as distinctive rings the called set with a distinctive
ring. The distinctive ring is determined by the index configured for the calling
set. This takes precedence over DRDN.
Group Call
Distinctive ringing takes priority over the ringing cadence selected by the
DRDN feature.
