10.59.4.2. Ring Cadences 
In order to receive the US ring cadences the following must be done.
- For digital devices the following command allows usage of hard coded
ring cadences for usage in the US.
CHANGE-ZAND:TYPE=ALLDATA2,USRINGTY=K;
- For anate stations the ring cadences are hard coded in the loadware. In
order to access this branch of the loadware the following ZAND command
is used.
CHANGE-ZAND:TYPE=ALLDATA,CNTRYCD=K;
IMPORTANT:
The programming of the ring cadences by PTIME will have no affect when these parameter are set to K. - In order for the appropriate rings to be given for the US features the
following ZAND command is used.
CHANGE-ZAND:TYPE=RNGTYPE,DSS=TRPR,FWD=TRPR,EXTCO=DBLR1, NORM=SGLR1,RMDCALL=SGLR2,NVCE=SGLR2,MSGRCALL=PRR,MT=MTR, CBK=TRPR,RECALL=TRPR,COMGROUP=SGLR2;
IMPORTANT:
Even though the parameters above suggest single, double and triple rings this is not true for the hardcoded US ringtypes. For example DBLR2, SGLR2 are actually triple rings.RingtypeRingCadencePatternonoffSGLR1100 ms3000 msRepeatSGLR2250 ms250 ms250 ms250 ms1000 ms2000 msRepeatDBLR1250 ms500 ms250 ms3000 msRepeatDBLR2250 ms250 ms250 ms250 ms250 msStopTRPR250 ms250 ms250 ms250 ms250 ms2750 msRepeat
