Help! Need someone to config Terayon CMTS

Forums: 

Hi, as the title says, I need someone to config a Terayon 3200 series cmts with provisioning software, preferably from the UK or mainland Europe just in case on-site config is necessary.
Also, need config files, and probably ongoing support.
Manual for this cmts would also be helpful.
Can anyone point me in the right direction?
Many thanks

Not getting proper upstream traffic

I am using 3.2 MHz channel width for one upstream but I am unable to get more than 2.5 mbps rather than ~ 5 mbps.Attached the utilization graph.

Pls suggest to overcome the problem.

Maxmimum data date for upstream

Forums: 

Hi,

I have configured my all 4 upstream ports channel-width to 3.2 MHz.Since I am using QPSK modulation for upstream,I can get maximum upstream bit rate 5.12 mbps.
As I have 4 upstream ports for one downstream, will I get 5.12 mbps upstream separate throughput across all upstreams? or 5.12 will be aggregate for all upstreams? Pls suggest

Modem Config Files

Forums: 

When you have a mix of modems, and a mix of CMTS's, can you create one modem config file with both 1.0 and 1.1 support?

Any samples out there? We use Motorola 4100, 4200 and 5100. We would also like to update their firmware if anyone can help with that..

Thanks,!

dhcpd solution

Forums: 

Hi,

I got a lot of modems in bridge mode. So customers behind those modems get an ip from our dhcp servers.

Sometimes people connect their own modem and in that case the customers behind those modems should get an ip-address etc from another pool, so we can send them to a webpage explaining them to connect the modem we supplied and not a custom modem.

How can I set up our dhcp server like that? Can someone show me an example dhcpd.conf for isc-dhcpd?

Thanks a lot.

Motorola SB6120 modem in EuroDOCSIS 3.0

Forums: 

can Motorola SB6120 DOCSIS 3.0 be used out of box in EuroDOCSIS 3.0 network?

I have software for private CATV

Forums: 

Hello All,

I've developed a PHP web-based system that does billing, cable modem access, work orders, graphing, logging, VoIP provisioning... I started writing it in 2001 and have been using it in production since 2004. If anyone is interested and on a budget I can guarantee that this is the most affordable system out there. I can even customize it a bit to meet your needs. It's a one-stop solution.

CUDA 12000 Help

Forums: 

Hi, I am new to the DOCSIS world so I'm asking for some help. I want to setup a lab at home to learn how to get a CMTS up and running. I have purchased a CUDA 12000 from ebay and I am able to get into the box. What I need help with are these :

For lab purposes can I just connect the upstream and downstream to a 2-way spliter combiner an screw that to a modem or am I gonna have to get more stuff? Is there a way to do it like this?

How can I get my hands on CudaView? I don't think it is installed on the box I have.

US fluctuation levels at many homes after D3 roll out

Forums: 

We have this strange issue with 10dB or more of US level fluctuations and it eventually causes the modems to drop one or more of its US channels. This does not seem to be an issue with the hardline network since it is only affecting random modems while a neighbors modem on the same tap is fine. The problem seems to go away for awhile if we reseat the drop at the tap or ground block. We have tried changing fittings and it still seems to come back after awhile (next day or next week).

Need Help Adding Second uBR to Network

Forums: 

Subject pretty much sums it up.

Have our initial uBR w/NPE-G1 and four MC16C's at the wall of the MC16's capabilities during peak usage periods. Have a 2nd uBR w/NPE-G1 and four MC28U's wired up and sitting in the wings ready to go -- more or less. Also have four more MC28U's ready to put into the 1st uBR when I get the 2nd one fired up.
