This read-create RowStatus adds, deletes, or modifies entries in the programmable tone table, and creating a new entry requires supplying cvtcProgrammableToneFrequency, cvtcProgrammableToneAmplitude, and cvtcProgrammableToneCadence at creation time. Administrators use it as the control point for provisioning brand-new custom tones on the gateway. For example, an admin building a fully custom notification tone would set the frequency, amplitude, and cadence objects together with this row status to bring the new tone entry into active use.
