Docsis chat

Hello all
I've been struggling with this for some time now, and thought I'd put it out to the hive mind and see what y'all are doing. We're trying to implement an automated system for dealing with the ever present issue of virus infected CPE equipment.

I'll start with a short-ish background of what we're doing and how it works, and then pose my question/ comments:
We admin a small Cable ISP. They run a Cisco uBR7223, and all the IP level stuff is based on Free and Open Source, Linux based software running on off the shelf gear. Some of it is modified to work and do what they need.

Arris eMTAs work very well with sip, however getting them initially provisioned can be tough.

I have successfully deployed docsis 1.1 arris eMTAs with dhcpd using SIP. I am going to post my configs here sanitized of course for others to learn from.

Hello

I'm searching for linux compatible command line tool that allow to generate configuration file for MTA.
I've found some tools tha generate simple CM files but neither support Telephony options ...

I would like to use "GUPI" and put one file per mta on our TFTP server ([macaddress].bin)

I want to generate on the fly MTA files from mysql database and php with SIP required informations without
use packet ace. My idea is todo everything from a webgui ...

Thank you for you help
Regards

My company currently purchases a DOCSIS embedded cable modem module from an ODM and modifies it for use in our product. We are interested in selling this product in Europe and are trying to find all the changes necessary for it to work in a EuroDOCSIS system. So far we have changed the diplex filter and recompiled the application FW for EuroDOCSIS operation. From my research, some or all of the BPI+ certificates will have to be changed.

Hi Folks,

If the following sounds too basic, then you are correct since I am very new to CMTS world. Now to my question

Given the following:
GigabitEthernet2/0/0

I understand the first string (GigabitEthernet) represents the "media type"
2 represents the "solt #"
0 represents "port #"

I would like to know what the last number is for ?

Thanks in advance

Hello all!
I've got what I suspect to be a simple issue here... I'm an IP network guy by trade, so forgive me if this is a ridiculous question :)

I have a CMTS with a downstream that's loaded. I have a second linecard that I'd like to activate, and have split the HFC plant (or a node, specifically) to accomodate this: I now have physically separate up and downstream paths for the node so that I can run my second linecard on that node, and run our busiest node on that card.
We run the ISC DHCP server on linux boxes behind the uBR using the cable helper-address config directive.

Hello,

Has anyone been successful in compiling docsis-0.9.5.tar.gz on Debian?

Thanks,

Hello,

I am using Arris C3 CMTS in the network more than one year. The machine worked well all this time. A few days a go I detect some problems with transferring of CMs config file from TFTP through this CMTS to CMs.

On C3 is 290 CMs. First approximately 210 CMs immediately download their conf file. CMs which try to connect after approximately 210 successfully registration complete CMs, they needed more than 15 min for downloading there config file. On cable modem log is the message TFTF request sent but no response received.

I have a Motorola BSR 1000 EuroDocsis 1.1. with this configuration
