Upstream supports 6 DOCSIS 3.0 channels, spectrum range: 5-85 MHz
Upstream Tx power of the CM: 40 dBmV
Upstream attenuation of the cable line: 20 dB
Fixed attenuation inside the CMC: 12 dB
NOTE
Use the MA5633 (D3.1, Cable Outlets on a Single Side) as an exmaple.
Rx power of the CMC DOCSIS module: 6 dB. Therefore, the upstream attenuation is 2
dB (40 - 20 - 6 - 12)
Upstream signal slope of the frequency mixing board: 2 dB.
Configure the Tx power of 32 DOCSIS 3.0 channels.
huawei(config-if-cable-1/1/0)#cable downstream 1 frequency 109 channel-mode
docsis annex AnnexB rf-power 32
NOTE
This configuration method is similar to other DOCSIS 3.0 channels.
Configure the Tx power of 32 EQAM channels.
huawei(config-if-cable-1/1/0)#cable eqam-channel 33 frequency 302 rf-power 32
NOTE
This configuration method is similar to other EQAM channels.
Configure the Tx power of the OFDM DOCSIS 3.1 channel.
