Sorry, should have hit preview, part of my replay got cut (Must remember don't use angle brackets). It should look like this:
The problem is DOCSIS won't be only using frequencies below 55 MHz. The upstream frequency will, but the downstream frequency will be above that. That is the one that will need a custom made window filter to isolate that 1 channel. Some Band pass filters are cheap, but for something like this you would need a filter with a very sharp frequency cutoff in order to isolate a single channel without allowing any bleeding of adjacent channels. That type of tolerance will not be found in a simple $5 part. Why won't the cable company do that? That would be alot of work for a small number of customers. For the prices most cable companies charge for cable modem service, would the extra support needed for this 'non-standard' setup be worth the returns? I would think that most cable companies wouldn't even consider it
