Parameters
<slot/ch[.0]>
The upstream slot/channel[.logical channel]. It will assume lc=0 if needed and not supplied.
{<0-16>-<0-16>}
This is a binary exponential algorithm which sets the start and end value for the data backoff. The valid range is 0 to 16. The default
settings are 2-8.
Where:
The first <0-16> is the valid range for the start value
The second <0-16> is the valid range for the end value.
You must enter the start and end values separated by a dash. The start value must be less than or equal to the end value.
