Information about OFDM Channel Configuration
OFDM Channels
DOCSIS 3.1 introduces modes for higher throughput and higher spectral efficiency while still allowing backward compatibility to DOCSIS 3.0. OFDM Channel support includes 1 OFDM channel per port with channel bandwidth from 24 MHz to 192 MHz wide.
Each OFDM channel supports a control profile, an NCP profile, and up to 5 data profiles. Profiles support one or more modulations.
Channel Profile
A globally configured OFDM channel profile contains channel parameters, and the modulation or modulation profile associated with the control, NCP, and data profiles.
Each OFDM channel must specify an OFDM channel profile in its configuration.
Modulation Profile
A globally configured OFDM modulation profile assigns different modulations to ranges of sub-carriers, or lists of individual sub-carriers.
A modulation profile may be assigned to a control, NCP, or data profile in a channel profile.
Path Selection
DOCSIS 3.1 Path Selection feature is enhanced to support OFDM downstream channels and OFDMA upstream channels. The RCC/TCS decision process is enhanced to include OFDM and OFDMA channels.
How to Configure OFDM Channel
Configuring OFDM Channel Profile
To configure the OFDM channel profile, follow the steps below:
enable configure terminal cable downstream ofdm-chan-profile id description text cyclic-prefix value interleaver-depth value pilot-scaling value roll-off value subcarrier-spacing value profile-ncp modulation-default mod_prof_id profile-control {modulation-default mod_prof_id | modulation-profile mod_prof_id} profile-data channel_data_prof_id {modulation-default mod_prof_id | modulation-profile mod_prof_id}
Verifying OFDM Channel Profile Configuration
To display the OFDM channel profile details, use the show cable ofdm-chan-profiles command as shown in the example below:

Configuring OFDM Modulation Profile
To configure the OFDM modulation profile, follow the steps below:
enable configure terminal cable downstream ofdm-modulation-profile id description text subcarrier-spacing value width value start-frequency value assign {modulation-default mod_prof_id | modulation mod_prof_id {list-subcarriers {freq-abs | freq-offset} value | range-subcarriers {freq-abs | freq-offset} value width value}}
 Note | Subcarrier spacing must match the subcarrier spacing of each channel profile in which it is configured. |

To display the OFDM modulation profile details, use the show cable ofdm-modulation-profiles command as shown in the example below:

Configuring Port/Controller and Channel
To configure the port/controller and channel, follow the steps below:
enable configure terminal controller integrated-cable slot/subslot/port max-ofdm-spectrum value ofdm-freq-excl-band start-frequency value width value rf-chan start_id [end_id] ofdm channel-profile id start-frequency value width value [plc value]
Note | The range of start_id is 158 to 162 in the OFDM channel configuration. The maximum OFDM spectrum is assigned to OFDM channels, which is used by the the CMTS to calculate default port base power. Ranges of frequencies can be excluded from all OFDM channels using the ofdm-freq-excl-band command. |

Clearing the Path Selection Status
To clear the path selection status for all CMs, use the clear cable modem all path-sel command as shown in the example below:
Router# clear cable modem all path-sel Router# show cable modem c8fb.26a6.c46a path-sel CM c8fb.26a6.c46a Path-Sel Info: N/A Path-Sel status has been cleared after register online.
Verifying the RCC Configuration
To verify the runtime RCCs on a cable interface, use the show cable mac-domain rcc command as shown in the example below:
Router# show cable mac-domain cable 7/0/0 rcc RCC-ID RCP RCs MD-DS-SG CMs WB/RCC-TMPL D3.0 D3.1 4 00 00 00 00 00 16 0 1 WB (Wi7/0/0:0) Y Y 5 00 00 00 00 00 25 0 2 WB (Wi7/0/0:1) N Y 6 00 10 00 00 08 8 0 0 RCC-TMPL(3:1) Y N 7 00 00 00 00 00 4 0 0 WB (Wi7/0/0:4) Y Y

Example: Configuring OFDM Channel
Note | The OFDM modulation profile must be configured before the OFDM channel profile which references it. |
