Exactly how does this work?

dpH between the Hub and the hybrid LNB.
dpX between the Hub and the Hopper 1/2 or SuperJoey (Advanced Client).
dpZ between the Hub and the Hopper 3.

The hubs allow Joeys to be added to the Hopper 3. Oddly enough, a node is required between the Hopper 3 and the hybrid LNB even in a setup with no Joeys.

I do not have a band plan for dpH/dpZ.

 

There is a MDU setup where 32 Wallys can be connected to the new DPH42 switch (16 Wallys per switch output using standard splitters after the switch).
But the biggest difference between most DISH wiring and DIRECTV's SWM is the use of 500 MHz blocks.
The Hopper 3 and the Wallys are the only receivers I know of that work with smaller blocks. (Joeys do not receive satellite signals and can be used with normal decent quality spliters.)
Perhaps DISH decided to put their development time in on their GUI instead of on signal distribution?
With home run cabling (their standard since DISH started) not having smaller blocks was not an issue until DISH introduced a 16 tuner receiver.
DISH has also used QAM for distribution in MDU settings.

 

Basically correct ... with the note that the second output from the LNB will still be below 2150. The node will raise it to the higher frequency.

 

Go to Menu ... Settings ... Diagnostics then "Dish" and your receiver (Hopper or Hopper 2) will show you what it can see. The type of node and switch should be listed at the top.
Based on that knowledge, the receiver knows what commands to send to the node.

During initial setup or a later Check Switch ("Test Installation") the receiver steps through the commands sent to the node and switch to determine what orbital locations are available based on the commands sent. On older receivers this scan process can be long.

In some cases DISH switches can be cascaded where the receiver sends commands to the first switch and the first switch sends different commands to the next switch.

 

Reading the type of node and switch is a two way communication. The old way of blindly sending commands and seeing what signals return has been modified when the receiver knows that it is connected to a solo node and a DPP 1K.2 switch (as the thread starter's equipment would likely report) or a duo node and a DPP 1K.4 switch as my equipment reports. Check Switch on my receiver is under a minute instead of the long blind process.

Two way communication would be a requirement for multiple Wallys connected to a DPH42 switch. Similar to DIRECTV SWIM the Wally would need to know which feed on the cable was for that receiver. But it is not new. DPPlus has been around for a long time and the ViP receivers have been able to identify DPP switches by name since they were introduced (2005 ?).

 

I have not seen a map for how the channels are stacked on DISH's "dpZ" feeds. The stacked feeds would be seen from a hybrid LNB via a hub connected to a Hopper 3 or the DPH42 switch on feeds to a Hopper 3 or up to 16 Wallys per output in an MDU setup. 51.03 MHz spacing would certainly work for DISH's 16 transponder per feed stacking.

Maxlinear has a switch that can do a 24 channel (individual transponder) stack or full band stacks. I assume that is used as the switch in the hybrid LNB (which outputs two dpX feeds OR one dpZ feed). DISH only uses 16 transponder channels on a stack but early rumors were that they would eventually use all 24.

DISH's topology was still one receiver per feed from the "hub" when the hybrid was released. They have since introduced the DPH42 switch that does stacking that can be connected to one Hopper 3 or up to 16 Wallys per output in a MDU installation. That is the closest DISH has come to SWM.

I assume the control language is similar but different enough that one could not connect four DIRECTV inputs to a DPH42 and expect it to serve two SWM feeds.

The DPH42 can support two Hopper 3s (one per output) or up to 32 Wallys (16 per output).
