How to change the CMTS from DOCSIS 1.1 to DOCSIS 1.0

Every DOCSIS 1.1 Device (CMTS, CM) should be downwardly compatible. If you want registration DOCSIS 1.0-Devices on CMTS you must this Cablemodems give a DOCSIS 1.0 Configfile. If you give a DOCSIS 1.0-Device a DOCSIS 1.1-Configfile, the DOCSIS 1.0-Device will abort registration on CMTS but give you a DOCSIS-1.1-Device a DOCSIS-1.0-Configfile will the DOCSIS-1.1-Device provisioned as DOCSIS 1.0-Device and all features of DOCSIS 1.1 are disabled.

I hope a could help.

Hi,
I Want the ARRIS CMTS to be Configured in DOCSIS 1.0 mode. I am looking for the CLi or method to do it. I am doing some testing, so I need to configure the CMTS in 1.0mode

Hello,
i don't understand why you want this? Which features will you get?

Let me repeat: DOCSIS 1.1 is downwardly compatible to DOCSIS 1.0.

Why not just contact Arris Tech support?

1. change downstream modulation to 64QAM
2. change upstream modulation profile to 1 (modulation = qpsk)

but this is decision like fromnt attack.

In details - all you need to do is to create docsis 1.0 cable modem configuration file.
Here is some sample:

03 (Net Access Control) = 1

04 (Class of Service Encodings Block)
S01 Class ID = 1
S02 Maximum DS Rate = 12288000
S03 Maximum US Rate = 2048000
S04 US Channel Priority = 0
S05 Minimum US Data Rate = 0
S06 Maximum US Xmit Burst = 0
S07 Privacy Enable = 1

17 (Baseline Privacy Configuration Settings Block)
S01 Author Wait Timeout = 10
S02 Re-auth Wait Timeout = 10
S03 Author Grace Timeout = 600
S04 Oper Wait Timeout = 1
S05 Re-key Wait Timeout = 1
S06 TEK Grace Time = 600
S07 Auth Rej Wait Timeout = 60
18 (Maximum Number of CPE) = 1
35 (Sub Mgmt Control) = 00 00 00

37 (Sub Mgmt Filter Groups) = 00 00 00 00 00 00 00 00

Enjoy it
