HAPTER 18: CONFIGURING AND MONITORING CABLE MODEM TERMINATION SYSTEMS
Configuring the Downstream Channel
The Downstream Channel sends data from the headend to cable modems.
Configuring the downstream channel involves setting parameters to
maximize the performance of the data transfer. Downstream channel
parameters are based on the modulation type for a downstream port on the
CMTS.
The downstream center frequency range values and the downstream
interleave depth values are different for DOCSIS and EuroDOCSIS. Refer to
the descriptions below for detailed configuration information.
Before You Begin
Before you configure downstream channels, follow this procedure:
1. Navigate to Network Browser > GroupName > ChassisName > Cuda
Chassis Manager > Configuration > CMTS > Interfaces.
2. Click the Interfaces tab. The Interfaces window appears.
3. Select the CMTS interface that you wish to configure.
4. Click the Downstream tab. The Downstream Channel window appears.
Configuring Downstream Channel Parameters
To configure the downstream channel parameters, follow this procedure:
1. In the Downstream Channel window, click the Parameters tab.
2. Enter values for the parameters. Refer to Table 18-5.
3. Click Apply to commit the information or click Refresh to return to the
default values.
