Configuring Downstream Channel Parameters
The procedure in this section specifies various parameters for downstream channel 0 of
slot 1 / interface 0. The available downstream channels on a DOCSIS Module are channels
0–3, which always correspond to downstream ports 0–3, respectively, on the HFC Connector
Module. Table 6 provides the valid ranges of all parameters specified in this section.

Enter the interface cable sub-mode, specifying slot 1 and interface 0:
G10$root# configure terminal↵
G10$root(config)# interface cable 1/0↵
Specify a frequency of 453000000 Hz for downstream channel 0:
G10$root(config-if-c1/0)# cable downstream 0 frequency 453000000↵
Specify an RF power of 55 dBmV for downstream channel 0:
G10$root(config-if-c1/0)# cable downstream 0 rf-power 55↵
Specify 64qam modulation for downstream channel 0:
G10$root(config-if-c1/0)# cable downstream 0 modulation 64qam↵
Specify an interleave depth of 8 for downstream channel 0:
G10$root(config-if-c1/0)# cable downstream 0 interleave-depth 8↵
At this point, if you desire to view the downstream channel 0 parameters and status,
enter the following command:
G10$root(config-if-c1/0)# cable downstream 0 show↵
Enable downstream channel 0:
G10$root(config-if-c1/0)# no cable downstream 0 shutdown↵
