Hi,
Currently I am using DOCSIS 3.0 with modulation profile 2 created for upstream modulation type 16 QAM with 3.2 MHz channel width. This way I can get Max throughput of(4*2.56=)10.24 mbps. Modulation profile 3 is created for 64 QAM. By using 6MHz channel width, I can get ~ 30 mbps throughput.
Is it mandatory to use channel width of 6 MHz for profile 3 or can I use with channel width of 3.2 MHz .

Hello robart,
looks like a Casa modulation profile ;) However, you can use modulation-profile 3 even on upstream channels with 3.2 MHz channel width.
Hi Gentlemen! I am trying to register a cable Modem to a 5Mbps bandwidth, but even if i create a config file with MaxRateSustained of 5Mbps, it reaches only 2Mbps. Could you help me?

Thank you Very much
Tx dear,
Since we have not changed th B/w, I understand there will no impact of noise even after changing modulation from QAM16 to QAM64.
What I've learned and recommend
Qpsk 18 and higher
16Qam 21 and higher
32Qam 25 and higher
64Qam 28 and higher
Carl
