Docsis chat

Hello,

Does anyone have a cure for echo on a docsis phone system? I use Arris TM402Ps, a CMTS 1500, Asterisk and a VoIP provider that is the same as my T1 provider so the network is fine. The upstream SNR is 34.9db. I have this old lady that says she hears her own voice. Believe me, I'm not ruling out mental illness either. Could it be the phone?

Thanks,

I have configured my CMTS BSR1000 below you can see my start-up config but i have one problem non of modems do connect to connect to BSR , i have tried all modems , Motorola , Scientific Atlanta , Thomson , but none of them worked.

In every modem when i log in to see the logs i get every time this error : " SYNC Timing Synchronization failure - Failed to acquire QAM/QPSK symbol timing "
Want to point one more thing here in Motorola Modem i only have a flash light at recive and never going below to send.

I bought one of these used. It's running T-SLM-RELEASE-4.1.3. Anyone have a more recent version?

Hi, does anyone knows if the motorola bsr2000 supports wccp (web cache communication protocol) for the traffic redirection for a cache server.

Thanks in advance

Hi,

I was wondering what factors determine which upstream card a modem connects to. Say I have an Arris C3 with two physical upstream cards and of course a downstream. All are mixed into the cable network at the same point. I understand that you can specify the upstream channel in the config file, but if you don't do that do they all just go to the first card?

Thanks,
Eric

I just recently ran across this project beta. Looks very interesting if stable. Anyone have any experience with it?

Hi there,

I've got a project where the customer wants to realise a multi ISP environment where
every ISP has its own provisioning-system.

The CMTS is a Motorola BSR2000. The documentation of this device points me to a configuration
server but this is a complete "blackbox" to me.

My first guess was the dhcp relay to direct the dhcp-requsts by mac-address but this seems not

Can I get some recommendations on a meter that will help in pin-pointing devices or connections causing high noise levels on the upstream side. We are experiencing high noise levels intermittingly on networks of ours...sometimes as low a SNR=6. I am looking for a meter that will help us find exact location of the noise problems on the network...we use CMTS 1000's on most networks.

Thanks
