Docsis chat

Even though I have configured with all possible setting,the scenario is still the same.i.e Single Logical channel 6/0/2:2 is not functioning.Can anyone help me through out this??

I took over for a small city owned cable system.

Details

Docsis 2.0
Cisco ubr7246 CMTS
2 channel down
4 channel up

550MHZ system

1 down channel qam 64
1 down channel qam 256

4 upstreams at 16qam

250mbps of available bandwidth
Currently utilizing 65 mbps at peak, sometimes 69

The packages they have set up are 4mbps, 2mbps, 1mbps with 1mbps up

Hi.

How can I set port mirroring on the Motorola BSR64K HSIM?
Is it ever possible on Motorola CMTS?

Hi
So i configurated my miniCMTS with DHCP,TFTP i enabled downstream and upstreams channels and everything is working fine i think.Problem is when i connect modem to the CMTS, modem will complete every step(downstream search ,ranging ,dhcp,tftp atd.) and after that every LED just go yellow and modem resets .So yea i dont understand where problem could be.

I didn't realize that this would be so hard to find....

If I have 1dB of light coming out the laser, what is that dB in RF?

If you have Incognito, that's even better.

I have had a hard time setting up service classes on our BSR's. Every time, I get these:

[10/16-12:57:02.09- 05:EVT]-E-RESSF.121 Failure to set provisioned QOS param set for CM 6019.7174.ff93, sfid 0, type US, svcClassName DefUGS, present 0x2147483881x, state 1, Index 20

Could someone email me a data dump from their BSR64K CMTS and a modem config file in plaintext format to merrimac at leuthcorps dot com ?

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.
