Network Distinctive Ringing (NDRG) allows a distinctive ringing cadence to
be configured throughout a Meridian network. Distinctive ringing is defined
on a route basis. There are four NDRG distinctive ringing cadence indices
that can be defined for a route. These indices are contained in the Flexible
Tone and Cadences (FTC) table. If one of these indices has been defined for
a route and an incoming trunk call over that route terminates on the local
node, the terminating set receives distinctive ringing. If the incoming call
tandems to another node via an Integrated Services Digital Network (ISDN)
TIE trunk, the terminating set at the terminating node receives distinctive
ringing. This occurs if the TIE trunk has been marked as distinctive and if the
NDRG feature is equipped at the terminating node; otherwise, normal ringing
is given.
