D-Link DVG-1402S manual Home VoIP Misc. Ring Cadence, Duration, Ring on Ring off

Home > VoIP > Misc. > Ring Cadence

By using the Ring Cadence window, you can set up to 8 distinct ring patterns. The ring pattern of each distinct ring can be configured by setting the On and Off time. The amount of times that the ring pattern will repeat itself can also be set.

Duration	This field is used to limit the amount of times that the ring
	pattern will repeat itself. For example, if a ring pattern is set for
	16 seconds and the duration is set for 60000 ms, then the ring
	pattern will repeat itself 3 times; then, 3 quarters of the way
	through the fourth repetition, the ringing will stop. The default
	value is 180000 ms.
Ring on Ring off	One ring pattern is comprised of four rings and four periods of
	silence. The On field refers to the time of 1 ring. The Off time
	refers to the period of silence between rings. One unit of time in
	the On and Off fields is equal to 50 ms; so a value of 40 in the
	On field sets a 2000 ms ring (2 seconds). The sum of all the
	fields must be less than or equal to 320 ms and must be a
	multiple of 8. However, individual On and Off times don’t
	necessarily have to be multiples of 8. A ring pattern could be
	set at 12, 12, 8, 4, 10, 50, 0, 0. While some of the On and Off
	times are not multiples of 8, their sum of 96 meets the
	requirement so this would be a valid ring pattern.
