I'm not sure what you mean by "this works with coax networking [DECA] and that is the limiting factor"? Can you explain further?
It looks like the primary difference between this and previous SWMs, other than five more tuners on a SWM output, is that the legacy outputs are stronger, similar to a SWM32, and based on the drawing, supported to cascade at least three levels deep. The SWM output maybe be stronger as well, assuming the "300 feet" thing means 300 feet to the 13th tap.
I wonder what the design target is for the output level at each tap? I guess receivers would need an output of -55 dbm, as IIRC that's what Directv considers the minimum output level they're guaranteed to work at. I think DECA may need more, but since it is lower frequency and experiences less loss through coax and taps designing based on receiver losses should keep DECA within margin.
What I don't understand is why using taps in this manner wouldn't work just as well on a SWM8. Am I missing something? Looking at the entire drawing, everything I see there could be addressed with current equipment as far as I can tell, by adding an amp and four way splitter off each trunk tap since SWM8s can't cascade (or using a single SWM32) and adding SWM amps to compensate for the assumed difference in SWM output strength. The only capability there is no substitute for is having 13 tuners from the SWM output instead of 8, which I imagine is probably the key to making this solution work for this market, otherwise it would have been marketed using SWM8s years ago, since the only missing piece is designing a SWM tap.
Is the difference between 8 and 13 sort of a "magic number" in terms of how hotels are typically wired? That is, is there a best practice that has typically been followed for doing the loop through wiring in hotels that says to not exceed 10 or 12 rooms on a single loop? Obviously if you have a hotel with >8 rooms in a loop a SWM8 is useless, but if you have >13 rooms in a loop the DSWM13 would be as well, so I'm assuming that typically hotels aren't wired with more than 13 rooms per loop?
He's maybe talking about the fact that deca has a node limit/ distance?
And for the reason 13 is so much more important than 8, look at the doc again. There is specific mention about the networking switch and how many it needs versus an older system... We are talking about a lot of money there too. The dre is evidently very much network driven...
Edit.. Vos beat me to it!
