Docsis chat

Hello,
The problem is that any client inadvertently or intentionally put cable which runs from the modem. Rather than add it to the WAN port of the LAN insert automatically consequently they begin to transmit DHCP in the system, which consequently most modems remain in status: 0.0.0.0 DHCP offer.

I tried to solve this problem but without success, I wish that someone with you to help.

With respect ....

Hi everyone;
I had a lab server running 3.5 and it finally died a couple of weeks ago. When I initially installed it I had a weird issue where some modems would come online and some wouldn't. Well since I have now rebuilt the server and installed 3.5 with the new features by bschirrmeister at https://github.com/bschirrmeister/docsis_server. It works great except I am running into the same issue I had before and I can't find the information that docsis_guy had sent me to fix it.

Hi there,

I was doing some testing related to classification encoding on the CMs. I was wondering if there is any way to relate a VLAN tagged packet incoming to the CM with a specific service flow on the upstream. I tried something like this:

Hi all

I am new on cmts, but I like to know how I can do

I have a uBR7246 - MC28U,

And I like to know what I need and configuration examenple to do downstream balance for the 8 upstream

I like to use ford all upstream the same freec 35Mhz, the Upstream separate and the 2 channel dowsntream on D0-627Mhz / D1-633Mhz

and all CM come equal register en the downstream channels, method by CM register .

I will be happy for your help.

Thanks and sorry for my bad English

I have a problem with load balance with dcc, I use Cisco Ubr 10K with IOS release 12.2(33)SCC7, the cable modem still go offline if I use dcc init tech 4, does IOS 12.2(33)SCC7 support for dcc load balance? or any one have experience to use dcc load balance ? can u share your configuration please? I need if cable modem change the channel cause load balance function work, it will go directly to use new channel without re registration or rangging again.

Thank for you help!

Hello,

I have a UBR7246 and I get slow upload speeds for everyone. It's not RF and it's not our ISP's bandwidth. It's either the modem config file or the CMTS config. We have about 30 cable modems on this CMTS. From what I know, everyone has the same problem. If I have them go to speedtest.net they get ping around 30ms, downloads and around 10MB and up at about 0.24MB! The strange thing is that the Hulu people aren't complaining. The modem config file and the cable interface portion of the CMTS file are below. Ideas are help are greatly appreciated.

Hi there,

I'm a newby in this DOCSIS and Cable world, so don't hesitate to correct any of my flaws. I was wondering what's the best frequency you could/should use in your upstream? I want to scale for two stacked frequencies afterwards, but for now, let me know which is the best for one channel (my upper limit is 42 MHz because of physical limitations).

It depends on each node condition or you could use one generic frequency for all your US?

Thanks in advance.

someone know about CMTS PC-Based http://www.c9networks.com/products.html ?

Hi,

I am using DOCSIS 1.0. .Since downstream modulation is 256QAM.
This way I can get Max 37 mbps throughput.Now i have added new downstream card with New downstream frequency (different from previous one).Now can i multiplex both the downstream and feed to single transmitter?

Hi everyone,

i would like to know if you have any idea about how to "build" kind of simple CMTS environment for using in laboratory. something
like a card (ethernet -> coax? pci? usb?)... do you know if have any product like that?

because in my project, i need to provide internet access for cable modem like a SVG1202[1]
