Procedure
l
Use a cable initialization profile to configure RF port parameters.
1.
Configure the frequency spectrum range and channel type.
In this example, the channel is of the European type. To change the type to North
American, run the
cable
command.
2.
Configure RF port parameters for upstream channels and activate the upstream
channels.
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 parameters for
upstream channels:
–
Number of upstream channels: 4
–
Frequency bandwidth of the channels: 3.2 MHz (default value)
