Setting the Power Levels and Frequencies

The power levels must be set correctly to ensure correct operation and compliance with the governing

regulatory bodies (such as the FCC). After the power settings have been determined, use the following

commands to conﬁgure the router.Refer to the following subchannel map as a reference for the

subchannel assignments:

Downstream Channel

Command Purpose

Step 1

Router(config-if)# radio transmit-power

power-level

Sets the upstream transmit-power to power in

dBm.

Step 2

Router(config-if)# radio downstream frequency

freq

width

Sets frequency and bandwidth for the downstream

channel.

Step 3

Router(config-if)# radio downstream subchannel

modulation-profile

Sets the subchannel and modulation-profile

assignment for the downstream channel.

Note This command specifies the center

frequency and width of the basic hardware

channel. The downstream channel itself

can be full, one-half, or one-quarter of this

bandwidth. For example, the only basic

channel bandwidth that is supported by

the initial hardware release is 6.0 MHz.
