Configuring the CiscouBR10012Router Using the Setup Facility
Configuring Individual Upstream Modulation Profiles
You can define individual modulation profiles. A modulation profile consists of a table of physical layer
characteristics for the different types of upstream bursts such as initial maintenance, long grant, request
data, request, short grant, and station maintenance.
Note Only qualified personnel should define upstream modulation profiles.
Complete these steps to activate upstream interfaces:
Step1 After the Setup facility has initially configured noncable interfaces on the CiscouBR10012router, enter
the enable command and your password (privileged EXEC).
Step2 Enter the configure terminal command to get into global configuration mode.
Step3 In global configuration mode, configure modulation profiles and spectrum groups for your
CiscouBR10012router using the cable modulation-profile and cable spectrum-group
commands.
Step4 In cable interface configuration mode, configure various characteristics for the interface in question,
using the cable upstream commands.
Note Refer to Chapter3, Configuring Cable Interface Features for the CiscouBR10012Router,” for
further information.
