Perform the following task within interface:cable:csi mode to set the
upstream channel width.
Slot Size
The Slot Size parameter is the number of 6.25 microsecond ticks in each
upstream minislot. This depends on one selected channel width, which is
automatically set when the user selects an acceptable channel width. By
default, the Slot Size is set at 2.
Following are recommended minislot values for different channel widths:
■
2 (3200 kHz)
■
4 (1600 kHz)
■
8 (800 kHz)
■
16 (400 kHz)
■
32 (200 kHz)
WARNING: The slot size affects the performance of the CMTS. It is
recommended that configuration is done by an expert-level
administrator.
