Wiring question

Good evening all,
This may have been asked a thousand times already, but kept getting confused trying to sort through all the back and forth between users and suggestions.

I will be receiving my new Roamio Plus tomorrow and picked up my CableCard & Tuning Adapter from TWC today to be prepared.

Would it be possible to have the following connection layout confirmed before I try hooking everything up tomorrow? I am planning to set up MOCA as I do not have a hard-wire CAT5 line to where the Mini will be and I don't wish to use WiFi to carry the streaming.

Code:

---

To TWC    POE      Tap  4-way
◄═════════████══════╦══════╦════███ Terminator (spare)
        Filter    ║      ║
                    ║      ╠════███ Tivo Mini
                    ║      ║
      Cable Modem ███    ╠════███ TWC STB (bedroom)
                          ║
                    2-way ╠════███ Roamio Plus
                          ║    │
                          ║    │USB connection
                          ║    │
                          ███═══███ Cisco STA-1520
                          POE
                        Filter

It's my understanding that the POE filter is required before the Cisco Tuning Adapter due to MOCA freqs causing issues with the device. If this is not necessary, please let me know!

Thank you!
Dan

p.s. Yes, I did previously run an old-school BBS and also ran a bunch of batch file menu scripting back in the good old days of DOS. Hence the old school ASCII character usage for the layout. =)
