Docsis chat

Hello,

I'm used to measuring the network quality by it's SNR or SNR Equalized values, this is not my field but I learned a lot along the years.

I have a SNR upstream of 33 a Equalized of 36 Micro reflections = 35
quantity of errors vs no errors or corrected seems ok

Dear,

I'm new in this area of ​​DOCSIS / HFC and the company I'm working received a Cadant C3 CMTS to configure, but I'm not able to configure it. Actually I can not access the command prompt via the console terminal. Always prompts user name and password, this is normal. Is there a default username and password? It should not be like the cisco equipment where the first access via terminal is released without a password and then the settings are made.

It is necessary to update the firmware first? If so could inform the correct procedures to perform?

We offer cable internet service as well as a VoIP service which uses a Linksys ATA to our customers and we're trying to find a way to essentially make a 'voiceonly' modem config that will block access to all addresses except for our class 5 switch's session border controller and our ATA provisioning server and 'support' servers like our NTP cluster and so on.

I have a uBR7246VXR with MC-16S Cards (Running D1.1) and cant find good documentation for apply security on this system.
I heard that BPI and Pre-Shared Key are the best options using this CMTS.
Does anyone know how to implement them in the CM files and CMTS?
How and where I create those Certificate?

I could use some help...

Regards.-

Hi all,

Hello All...

I wonder if anyone know how to force a CPE to get an IP from a pool based on CM MAC Filtering, not using a specific Ethernet CPE MAC... In other words, I need that CPEs behind determinated cable modems get an IP from a pool destinated for that cable modems CPEs.

Some idea?

Hello,

7246VXR Not showing mc16u cable linecards, looks like a chassis boot issue for some reason.

I'm trying to help some with an old vxr platform. While the chassis has 4 mc16u cards in it, none of them show in the configuration. Any ideas on what's missing? Wrong IOS or what???

Dear,

with this configuration makes itself known to a modem. And when I look at the integrated interface 1/0: 0 Streaming it is turned on.

I have an Arris CMTS 1500 and I want to do DOCSIS 1.1 configuration files to give priority to VOIP rather than data.

I am sending the following configuration file.

With these parameters is sufficient or I need something more in order to make priorities?

Main
{
NetworkAccess 1;
GlobalPrivacyEnable 0;
UsServiceFlow
{
UsServiceFlowRef 1;
QosParamSetType 7;
TrafficPriority 3;
MaxRateSustained 128000;
}
