Re: [WISPA] Cable network for Internet, VoIP and Video distribution
Javier, If I'm understanding the question correctly, which is basically "Can I send DOCSIS over IP networks (wireless or otherwise), the answer is no. If you think about it in terms of OSI model, it will become a little clearer--the CMTS use a QAM to read the RF signal and pull the Ethernet frames (this is layer one / layer two); your basically asking if that information can be encapsulated inside of a layer-3 IP packet (and the answer is no). There are DOCSIS over wireless solutions (look at various "wireless plant extensions" for more detail) that basically shove the RF out over wireless instead of out the HFC plant, but that doesn't seem to be what you're looking for... What problem are you trying to solve? I'm assuming there is some reason why you aren't just using IP wireless links directly to the customers -Clint Ricker Kentnis Technologies On 9/25/07, Javier Arigita <[EMAIL PROTECTED]> wrote: > The CMTS does have ethernet interface.

Re: [WISPA] Cable network for Internet, VoIP and Video distribution
The CMTS does have ethernet interface. The problem is the distribution of the video data and voice. The CMTS seem to have an IF (intermediate frecuency) interfaces and coaxial interfaces. The IF if is meant to transmit the CMTS "signal" over wireless links (not IP ones of course), the coax ifs do the same over coax lines. I would like to transmit that "signal" using IP wireless links (such as Alv B100 or whatever) to other areas. If we do not manage to do that we will have to install one CMTS for each area and that is really expensive. Many Thanks for your responses.

Re: [WISPA] Cable network for Internet, VoIP and Video distribution
The Motorola PTP 600 radio support both Ethernet and T1 interface. Not sure which CMTS you are refer to, but the compact CMTS/Router does have Ethernet interface, does that combination will work?

Re: [WISPA] Cable network for Internet, VoIP and Video distribution
If they're only going to use 1 CMTS then you must get wireless links that shoot video, which will pretty much kill any IP wireless links in the area running on the same channel. A CMTS usually must have a management server for provisioning & management, so you could buy several cheaper CMTSs (I purchased a used Nortel/Arris CMTS1000 years ago and it's never had a hiccup) and place them at each site, linking them to the management server via wireless links. I've also investingated DOCSIS wireless radios (they'll just do the data part). The problem with all this is if you don't have some kind of circuits (wired or wireless) between the sites, then you'll have to have feeds for all the channels you're going to provide at each location. Depending on mileage, you may be able to use dry copper circuits. I know that some of this can be done over T-1 circuits, but the project I'm involved in didn't go that route, so I never spent too much time on it. Hope this helps.

[WISPA] Cable network for Internet, VoIP and Video distribution
One of my customers is designing a Cable operator network for several estate areas. They plan to use a Motorola CMTS device to serve those areas.
