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

Hi All,
I have been going through the DOCSIS 1.0 spec from past few days ... the one question that I often get is that, On what basis does the CMTS authorize a CM?

The following explanation is given in DOCSIS 1.0 BPI specification ..

Baseline Privacy initialization begins with the CM sending the CMTS an authorization
request, containing data identifying the CM (e.g., MAC address), the CM’s RSA public key,
and a list of zero or more assigned unicast SIDs that have been configured to run Baseline
