Docsis chat

Hello,

I have some some Arris CMTS 1000 for testing CATV measurement equipments.
Now I have trouble. Some equipments can't link up to CMTS 1000.
Therefor I want to change firmware version (Current my CMTS1000 version is 3.3.318).
But I don't have firmware files.

Could anybody give me firmware files?

Sincerely,

We finally got our block of IPv6 addresses and are hoping to be able to utilize them. I was curious to know how different the setup would have to be for IPv6 vs IPv4 and are there any issues we needed to be aware of ahead of time? Everything on our network is currently still IPv4 but our DHCP server supports both IPv6 and IPv4 so at least on that side we are covered. We have yet to deploy DOCSIS 3 as well.

Dear,

I have the following situation.

- CMTS uBR10K with PRE-4 with two channels of upstream 6.4Mhz in QPSK modulation. on average 150-200 only cables modens docsis 2.0 on each channel beyond 3.0

              I intend to pass the upstream channels to 16QAM modulation with minimal impact due to the SNR. If SNR increase I want the modulation to pass to QPSK. I will use the following modulation-profine:

Does anyone have recommended modulation profiles for the Casa C100G?

We are looking for 16QAM and 32QAM ATDMA profiles. We do have a 64QAM ATDMA profile that is a default on the CMTS.

Hello,

i am testing CASA C40g and multicast setup..

i see mcasts are on qam/ofdm interface.. but i cannot see them behind cable modem.
I have mcast grroup defined in cable modem config file. Actually that config file worked ubr7200 setup.

Any idea where could be a problem? are there any extra settings for casa cmts?

Hello

I was tasked to test the data communication between the DAH100 and the modem EPC3010.So i am not sure what other things to use.Is RG-6 cable with F-connectors okey ?And how to connect 2 outputs(downstream upstream) into modem , i guess i should use some kind of splitter right?

Dear,
            Could anyone provide me a good example of modulation-profile cable for A-TDMA channel 6.4Mhz 16QAM which when noise increase pass to QPSK?

Thank you.

Hello,

hello we have a problem in this cmts, the cable loses pinging packets for ipv4 from cmts, and for ipv4 from the network,

We already changed the smms, the chassis, the sfp, the optical cord, and the problem continues.

thank's for your time.

Dear all,

I was just reading about:

https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/ci...

Does anyone know if the command "cable helper-address" which provides the same function as "ip helper-address" is also affected by this issue? I guess yes, but the article just refer to "ip helper-address".

Unfortunately I do not have access to cisco support. Can someone send me the newest IOS software:
