Downstream Modulation
The Downstream modulation parameter sets the modulation rate for a
downstream channel. The CMTS supports the following two modulation
types.
You set the downstream modulation type by performing the following tasks.
Task
1. Enter interface configuration
mode.
2. Configure modulation used on
the downstream channel. Valid
values:
qam64: Set s the interface speed
at 30 Mbps
or
qam256: Sets the interface
speed at 40 Mbps
