Can any one tell me what is the link between Interframe-delay and change-interframe-delay.
The Techinical Spec says
1: Yes, for the upcoming subframe only.
2: Yes, also reset default.
This field and all subsequent fields can be omitted as a
group if no frame parameters other than the framing mode
or the subframe name are changed.
4 bytes (unsigned integer). This field must be omitted
if the change-interframe-delay field is zero or is
omitted. The range is [0..2ˆ31-1] ticks.
My question is how will each option of Change-interframe-delay affect Interframe-delay.
