A "modem only" filter is just a "band pass" filter that only allows the downstream and upstream channels needed for the modem. It is certainly possible and common to get:

As are all sorts of other filters:

If the company installs a trap, it would have to allow a frequency range to be open for the cable modem to operate. Where I currently have service, (Comcast), it operates at 597 Mhz. If COX operates at that frequency for it's cable modem CTMS systems, then would anything that operates above that frequency, (channels 87+ analog) be transmitted as well?

I've heard that even with the trap, people are able to receive the local broadcast stations in DTV format.

I'm not trying to steal service or anything, but I'm just curious about the science behind the technology and applying this theory to a real world application, because in theory, if the filter blocks the frequencies lower than the cable modem operation, it would suggest that the other frequencies would still be unfiltered.

Thanks,
