5.1.5 Setting Additional Downstream and Upstream Channels
Use the “Vendor Specific Parameters” option to set additional downstream
frequencies and upstream channels. Your system engineer should tell you if this
is necessary. First enter the Frequency of the Additional Downstream Channel in
Hertz and then enter the associated upstream channel ID (ID of additional
Upstream channels). To add more downstream and upstream frequencies right
click on the “Vendor Specific Parameters” option and select “Duplicate” to bring
up another screen and enter the desired values.
A Downstream Scan Plan value of ‘9’ indicates that the downstream channel is
set to a permanent fixed frequency (the advantage is that the modem initializes
faster and doesn’t interfere unnecessarily with other traffic on the network).
