Burst-len
The Burst-len parameter is the maximum number of mini-slots that can be
transmitted during a channel's burst time. A value of zero is transmitted if
the burst length is bounded by the allocation MAP rather than this profile. By
default, Max Burst Size is set to 0 for all interval usage codes.
You set the maximum burst size by performing the following tasks:
.
Diff
The Diff parameter enables differential encoding on this channel. By default,
Differential Encoding is disabled. Differential Encoding should be enabled
when FEC is not used and disabled when FEC is used.
You set the differential encoding by performing the following tasks:
.
