Distinctive ringing (ringing type C3C)
The ringing signal for markets that have adopted the C3C ringing type (such
as Malaysia and Australia) is based on a 3 s cycle. The following figure
illustrates the distinctive ringing pattern for C3C ringing. There is no
distinctive ring 0 since this is considered to be standard ringing. Note that
distinctive ringing 1 (DRING1) for MBS sets differs from DRING1 for
non-MBS sets, but the remaining DRING patterns are the same.
