Selector 5 Minimum short-OFF duration in distinctive ringing
The ringer pattern consists of short and long rings, e.g., short-short-long rings. This selector sets
the minimum OFF duration following a short ring in order to avoid missing ringer tones in distinctive
ringing.
If this selector is set to "1," when the short-OFF duration is a minimum of 90 ms long, then the
equipment will interpret the short-OFF as OFF.
