Configuring the Downstream Channel 383
Downstream Frequency
The Downstream Frequency (Hz) parameter sets the downstream signal for
the RF carrier. By default, Center Frequency is set at 507 MHz. DOCSIS
acceptable values are 93 MHz to 855 MHz; EuroDOCSIS acceptable values
are 91.0 MHz to 858 MHz.
You set the downstream center frequency by performing the following tasks.
Channel Width
The Channel Width (MHz) parameter is fixed based on DOCSIS standards. By
default, the channel is set at 6 MHz, which is an acceptable value defined by
the NTSC channel plan. EuroDOCSIS modules operate over 8 MHz channels.
Channel width is shown as part of the show interface cable <c/s/i>
downstream display.
