I am a cable operator looking for someone who could set up an all inclusive solution for provisioning, etc. to launch my Arris 1000 CMTS in a new system. If you would send me your info at office@mptelco.com. Looking to move quickly. Thanks.

Terayon BW3x00 problem

Forums: 

Hello DOCSIS community,

I have a strange problem on some of the Terayon Bluewave CMTSs. These boxes have been in service for a couple of years now, without major problems. I use DOCSIS2.0 modems and configurations only, I don't have any older modems. The thing that happens is, some of the CPEs cannot access the DNS servers. Here are the simptoms:

- modems register without problems
- CPEs receive their IPs and other stuff from DHCP no problem
- CPEs CAN ping anything on internet (based on IP only)
- CPEs CANNOT resolve any FQDN

More data for time out cable modems

Is Thomson THG-540 being used in the US?

Forums: 

To date I am familiar with the Arris TM5XX and SA Webstar series eMTA being used in the US.

Any operators in the US using Thomson THG-540 for VoIP. If so, what CMTS are using.

Is it available through NCTC?

Arris TM502G, CMTS 1000 and Asterisk

Forums: 

Hello all,

Getting cable modems to work is a piece of cake for me. Getting Analog Telephone Adapters to work with Asterisk over cable modems is easy for me too. For some reason, I am having troubles with the EMTAs specifically the Arris TM502G. The funny thing is that I have access to Arris and ALL of the documentation. I have the cable modem part working fine. The thing I can't figure out is how to tell the Linux dhcpd.conf to send DHCP option 122 to the cable modem part of the TM502G to trigger the dhcp/tftp process of its MTA. Can anyone give me some clues on this?

Arris C3 CMTS

Forums: 

We just installed a Arris C3 CMTS and are sending the IF output to a EMCEE Transmiter for our MMDS wireless cable plant. The CMTS does not seem to be outputing enough IF to allow the transmitter to come on line fully. Any ideas?

Arris 1000 cmts needed

Forums: 

I did not know where to post something like this, but we are in need of a used docsis 1.0 cmts with 2-3 upstreams and 1 downstream. We would like if it could be Arris 1000 cmts, but any other unit can also be offered.

WARPERA Cemax CMTS

Forums: 

Hello,
I am trying to find any information regarding this CMTS device, but it seems that company does not exist anymore.
Can anyone share any light on these devices ? Are they any good ?

DOCSIS_SERVER - Has anyone got an opinion on it they care to share?

Forums: 

I am investigating developing or adapting an open source application for provisioning CMs and MTAs.

Does anyone who is using, has used or tried out DOCSIS_SERVER from accesscom.ca, care to share their experiences.

I am specially intrested in CM and MTA loads they have on it if they have it in production. Bad experiences if they have had any. Manual (human) effort in data entry.

Thanks
