Parameter Description
frequency and channel-width A central frequency and a frequency
bandwidth determine a frequency range,
within which packets are transmitted. For
example, the central frequency of a
European channel is 55 MHz and the
frequency bandwidth is 6400 kHz. Then the
frequency range of the channel is 51.8-58.2
MHz.
modulation-profile An upstream channel modulation profile
defines parameters for processing the signals
transmitted over the upstream channel. You
do not need to configure an upstream
channel modulation profile generally. Ports
automatically bind to profile 1 by default.
The following configurations are used as an example to configure RF port parameters:
– Number of upstream channels: 4
– Frequency bandwidth of the channels: 3.2 MHz (default value)

huawei(config-if-cable-0/1/0)#cable upstream 2 frequency 42.60 enable
huawei(config-if-cable-0/1/0)#cable upstream 3 frequency 49.00 enable
huawei(config-if-cable-0/1/0)#cable upstream 4 frequency 55.40 enable
3. Configure RF port parameters for downstream channels and activate the downstream
channels.
Parameter Description
modulation A greater modulation mode value for
downstream channels results in a higher
channel bandwidth but weaker anti-
interference capability. Therefore, configure
the modulation mode based on site
requirements. The default modulation mode
is QAM256. This example uses the default
setting.
The following configuration is used as an example to configure RF parameters for
downstream channels: A total of 16 downstream channels have been purchased.
