Docsis chat

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]

Hi,

Hi,

i have problem with config file on epc2425.

SnmpMibObject saRgDot11BssSecurityMode.32 Integer 7; /* wpaWpa2Psk */
SnmpMibObject saRgDot11WpaAlgorithm.32 Integer 2; /* tkipPlusAes */
SnmpMibObject saRgDot11WpaPreSharedKey.32 String "qwerty1234567890" ;
SnmpMibObject saRgDot11ApplySettings.0 Integer 1; /* true */

If i set this mibs in config file to upload to epc2425 - modem don't change this part. But if i gave it by snmpset:

I am using a linux box to reset some promlematic modems using http://www.net-snmp.org/wiki/index.php/TUT:snmpset but i keep getting need value when i use the docsisdevresetnow. Is there anyone on the forum that has an e?amle for me to review.?

Hello, The file is from Arris modem.

Just wanted to know about the Download and Upload Value and Info about this file and how can i change it to the bigger or lower value.

I reserve a small number of addresses in each of my DHCP public subnet pools for static assignments to businesses, etc. How do I prohibit a user from hijacking one of these unused addresses and simply plugging it into their setup? I presume it's a very simple class definition/designation and then applied to the host entry?

Could also use some help with a migration path to a third uBR and D2 from our humble little D1 setup using a pair of uBR's currently. D3 won't be in the cards for me until next year, so I need to make do with what I have for now.

Hello All,

I have some Arris C3's in some pretty remote locataions and need to know if the fans are dying. I've found this:
