Configuring the Downstream Channel 387
Example Procedure of Downstream Configuration

The following procedure steps you through the process of configuring a

DOCSIS downstream channel. An example of a DOCSIS configuration

follows:

Task Command
1. View a list of CMTS
interfaces that you have
installed on your chassis.
You can do so by using a
combination BAS/UNIX
command.
show topology | include docs
2. Enter configuration mode
for the CMTS interface that
you want to configure.
interface cable <c/s/i>
3. Display the current
downstream configuration
for this CMTS card.
show interface cable <c/s/i> downstream
4. Set the downstream
channel status.
■downstream no shutdown
(Sets the downstream channel status to up.)
■downstream shutdown
(Sets the downstream channel status to
down.)
5. Set the downstream center
frequency. Acceptable
DOCSIS range: 93.0 MHz to
855 MHz.
downstream frequency <freq number>
6. Set the downstream
channel interleave depth
downstream interleave-depth
