Hehe… Similar in design, but slightly different in terms of the topology used to create the network.
I'm about the only person that I know that still supports such an ancient technology from last century (1990's to be exact) such as MLPPP. Originally, it was used in the VERY late 80's, but more-so into the 90's as a means of bonding multiple DIAL-UP modems together to get a faster speed. In my case, I made a few configuration tweaks to turn MLPPP into MLPPPoE :funny2:
The key difference is that instead of bonding multiple dial-up modems together, I'm bonding multiple ADSL2 lines together. Sadly, I'm just over 5 KM from the SLAM, and sadly, the ENTIRE circuit is oldschool coagulated COPPER... We're not even lucky enough to have FTTN out here (although TFFC, FTTB, or FTTH/FTTP would be preferred), so in theory, I should only be able to qualify for a 1.5 meg profile... A little pimping out of my services and swapping out the shitty ass CAT3 from the NID at the side of the house to the POTS splitters inside the house with CAT5e, as well as upgrading the lines from the shitty ass telephone cables to a custom made CAT5e jumper all the way to the modem (among a few other changes that I made), and by some miracle of physics, I managed to get all 3 lines stable at a 4032/800 (4 meg) profile. What sucks though is that on the most part, lines 1 & 3 can handle a 5056/800 profile... Sadly though, line 2 for some reason will only handle 4032/800 if I want it to stay stable, which sucks because when you're talking 3 - 4 lines, a 1 meg drop on even ONE line will mean an overall reduction of speed by 3 - 4 meg (1 per line more or less).
Sadly, on 3 DSL lines, I'm still only cranking out 9.75 - 10.5 meg down, and a mere 1.8 - 2.25 meg up. Admittedly, the installation of line #4 this month is more for the upload speed than the download speed. From there, I had to get creative with the wiring to make sure that I would have decent, solid, and reliable WiFi both in the house and the trailer.... So yeah... Advanced networking has kinda become my forté. 
I also took the wiring for power and such to a whole new level, using a brand new car battery from a 2003 Nissan Pathfinder that my roomie's brother had kicking around, a car battery charger that I had kicking around in the basement, and a 150W inverter to convert the 12VDC to 120VAC, along with a custom ground adapter that first plugs into the inverter. It's a simple adapter really. It's just a short little about 6" long piece of 14 gauge wire with a male plug on one end, and a female plug on the other. On the female end of the adapter, I have an additional ground wire that connects to the ground pin, which runs over to the same clamp that clamps the ground wiring for the hydro (electrical) panel to connect to the water pipes (because we're on a well, so no copper piping actually runs underground, thus the water lines need to be grounded somehow). This way, I have the same 120VAC connection with a proper ground terminal, all running off of a 12V car battery. 
The concept is simple... When the hydro (electricity) is on and running, the car battery charger kicks in and both charges the battery AND runs the electrical load off of the inverter at the same time. When the hydro goes out, just like shutting your car off, physics kick in and the inverter begins to draw off of the battery seamlessly, instead of the charger. This way, the hydro has to go out for at LEAST 51 hours before I lose my precious internet. Inside the house, all the main network guts connect into the inverter, which consists of the FOUR DSL modems, the main Mikrotik router, the VoIP adapter, the main switch that links all the guts together, as well as the WiFi router inside the house. So literally in a power outage, the ONLY thing that keeps working inside the house as it is now is my precious WiFi and VoIP lines (which actually also run out to the trailer). Out at the trailer, I have a secret weapon... A 2003 Nissan Sentra, a pair of jumper cables to run the battery terminals into the inside of the car and keep the hood closed (for rain/show protection), a 750W inverter (which is powerful enough to run my ENTIRE trailer, except the electric heat, thanks to the magic of LED lighting), and a bigass extension cord to run from inside the car to the back of the trailer. Before powering the inverter on to be able to power the trailer, simply start the engine, and instantly, the alternator on the engine quite literally acts as a generator to maintain the charge in the battery, and run the electrical system inside the trailer for up to 48 hours on a single tank of gas. 
The next planned upgrade is going to be to run a second CAT5e cable to the trailer to run the VoIP lines only. That way, I can use the two spare pairs of wire in the existing CAT5e cable to run PoE instead of VoIP lines, which will allow me to upgrade the wireless router inside the trailer to one that can be powered by PoE. This way, my precious porn downloading will not be interrupted in the trailer in the event of a power outage, because although it may take me a few minutes to hook up the trailer, the wireless router that the laptop plugs into inside the trailer will be powered by PoE, and because of the nature of a laptop having a built in battery backup, not even my precious porn downloads will not get interrupted by a power outage.
I like to call my network style here "HARDCORE" :funny2: :funny2: :funny2:
You would almost seem to think that I run a home based IT business and got fed up with the frequent power outages (the inevitable result of living in the middle of nowhere squared) that were causing me a great deal of difficulty doing things like updating websites for a customer, or otherwise conducting my business online. As for the heat in the trailer, in the event of an extended power outage, that's what I have a propane stove and a fan for in the event that I need heat when there's no power. I have a little over 51 hours of emergency reserve power, and if I need more, I can just connect a second car battery in a parallel to the existing one and more than double the allotted time that I have. That being said though, the longest the power has EVER gone out here (with ONE exception) has been 33.5 hours. The only time it EVER went out longer than that was back in 2003. I was out for almost 3 DAYS as the result of the largest blackout in history...
Do I get the award for the most hardcore home networks setup? It's designed to more or less NEVER go down, even when the power goes out for an extended period of time.
