Docsis chat

Hello,
I have a BSR2000 CMTS, the US modulation is 64 QAM.

I have the next CM per channel:


VN-BSR2K#show cable modem s t
Interface Total Active Registered SpecGrp Group
Modems Modems Modems Name Id
Cable 0/0/U0 277 0 250 d0-u0 0
Cable 0/0/U1 144 6 128 d0-u1 0
Cable 0/0/U2 370 3 328 d0-u2 0
Cable 0/0/U3 295 0 270 d0-u3 0

Hey everyone,
Im just about gone nuts, bugeyed and drive to smoke twice as much over Arris TM402 eMTA modems.
We have approximately 150 of these units which we're purchased refurbs, GREAT cable modme, no issues, the eMTA = STRAIGHT from Hell.

Let me preface this with the fact I am not a Docsis Engineer, I just stayed in a Holiday Inn Express last night.

We provide internet services to apartment complexes, with fairly small cable plants (our largest is 150 modems). We continue to have issues at all of our sites, which I blame on plant configuration due to nobody knowing how to configure a Docsis plant. One very common issue we are facing is high levels of noise.

Here are our current settings:

Downstream:
QAM 256
Interleaver depth: 32
frequency: 747 MHz

Upstream:
QPSK - 2560K
Channel 1 freq: 40 MHz

Hello group...
I'm trying to get firmware and cert files for DCM-305 and think 301. I've got others in case you need them or trade lol
not like baseball cards, but just can't find it for those modems and need it to run some tests in my lab

Thanks in advance

Carl

Hi community,

Does anyone of you have any information/CLI commands on how to debug a Terayon 3200 CMTS?

The problem is, sometimes the CMTS looks like it puts on a CPE filter (which is not configured anywhere) and it blocks IP packets towards the CPEs on higher ports (i.e. dport > ~5000). Anyone have a similar issue or know how to do some sniffing/packet tracing on the CMTS?

Any help much appreciated...

Regards, b

I'm working on a setup to manage all of my modems in terms of creating a customer database in sql and making all of their statistics available from within their account. So far, I've written every stitch of code myself and it's quite tedious. I was curious if there are any open source solutions that can be modified to fit the description i've got. mainly, I'd like to be able to quickly search for a customer, pull up their account and see registration info, docsis counters/stats and maybe graphed info(that's what is slowing me up a bit right now).

Does anybody knows an SNMP OID to get temperature from Arris C3 CMTS?

Thx

Iliri

Does have any one can teach me the MTA config file ?

in the packetcable 1.5 spec
if use BASIC.1 service flow need to add the ConfigHash in the configuration file as below :
SnmpMibObject pktcMtaDevProvConfigHash.0 HexString 0xe82f54721b2af60127e0902b354f19d0e3aa9820 ;

but how to calculation the Config Hash ?
or have any function can pass the hash check ?
