Docsis chat

Hello all,

The Motorola dch3416 is a dual tuner DVR, digital set-top box and a DOCSIS cable modem. I am a SMATV operator. Does anybody have any idea where I would start to look for a way to program/provision this device? It's time the little guys used the big boys toys. This stuff can't be rocket science. Also, there is a cable card slot in the back for provisioning. I'm thinking of going all digital and this device can get me there. Any ideas and/or help would be appreciated.

Thanks,
Eric

hello all,

does any one here have implemented docsis with a radius server?

cheers,

I want to have 2 different DHCP servers on BSR 64K.
1 for CM & the other for CPE. CM is my primary host & CPE is the secondary host. What is the way out to use second DHCP server for CPE IPs ?

I am running BSR 64K with Docsis 2 Cards. I want to capture CPE with corresponding data - CPEs online with respective modem. Can i configure some event which can be logged to an external syslog server when a new CPE registers to CMTS. To be more clear, When a new CPE comes on the network, corresponding CM, CM MAC, CPE & CPE MAC should be logged somewhere - everytime.

How do i determine who has what public IP address on my network .......basically we have a cisco router 2611 router and a nortel cmts 1000 and i can see the private 10.0.X.XX range and i know who has it but i can not determine who has what public ip address on the CPE side of the cable modems.....i need this info because someone on the network with the 12.230.XX.XXX/24 range has malicious network traffic. I have researched the DHCP server and can see the mac address of the CPE device behind the modem but that doesnt really help me. Can anyone advise?

Can any body help me out to contorl on wire less connections behind CM from CMTS or DHCP or by TFTP .

Hello

I am testing some cable modems with MTA incorporated.I have some problems to get them online .I am using linux dhcp server that is configured to assign only CM IP address.
I want to provide three IP for the modem ,:CM.MTA.and WAN (for internet ) (class''CM'' class"MTA" and class"CPE-or not-docsis")
Please ,can someone send me a DHCP configuration that works .

Thank you,
Ilir

SNR problem in DOCSIS network

We got a BSR64k running in docsis 1.1. We have hooked a modem up directly to the back of it and it is running corrected codewords when streaming data over the internet with an occasional uncorrectable. Is this normal? We are thinking that this should be clean and not running any corrected data. We have tried different modems and slots as well (sb5101, sb5120, and slots 11,12,13). Corrected codewords are about the same no matter what.

Software - 3.1.1.16P05.KRCU
