The unit I suggested someone else try was this: http://www.planet.com.tw/en/product/product.php?id=26560 Which can be purchased in north america via (among others) Amazon.ca: http://www.amazon.ca/PLANET-VC-231-Ethernet-VDSL2-Converter/dp/B009WWHNWU for only $142.83 ea. You need two; one for each end. No DSLAM required. This unit only does VDSL2+ profile 30a on a single telco cable at a time, and may or may not be able to support profile 30a at all. If 30a works for you, though, that's 100Mbps symmetric.
There's also BlackBox gear that's similar - the LinkGain extender (50Mbps, http://ca.blackbox.com/Store/Results.aspx/Networking/Extenders/LinkGain/n-42...) and the entire Ethernet-over-UTP series (up to 100Mbps, http://ca.blackbox.com/Store/Results.aspx/Networking/Extenders/Ethernet-over...).
Of course, you can combine two pairs of VC-231s with two linux boxes acting as bridges, each one configured for round-robin, and get an aggregate 200Mbps symmetric out of the cabling.
Good luck!

This is an active area of research, particularly with the advent of multi-path TCP. Presently, however, you have to hide the two-link-ness from the TCP layer, and essentially from the IP layer as well. ECMP would work, as long as both lines are the same (this does not hold true as a dynamic assertion with DSL technology, *ever*). LACP will *not* work. If you have Linux boxes at both ends, you can use mod_bonding in its round-robin mode... I've done that in the past and it does work.
Far more effective, however, would be to upgrade to a symmetric VDSL2 setup that supports DSL bonded pairs. That'll set you back around $600+ per end, IIRC, replaces both the DSLAM and the DSLR, but makes your problems go away by turning all the copper into a single Ethernet link.
I just worked with someone else on this kind of setup, I'll see if I can find the links...

Is it possible to aggregate DSL lines, to combine them to get X-times the bandwidth on a single link? In this situation, I control both ends, the DSLAM and the DSL modem side on the other end of some POTS runs (CAT3-ish I assume, or worse). Note, I don't want load balancing or fancy routing/sharing. I need double (or more) the bandwidth for a single application (single TCP connection). If required, we can have linux/bsd boxes we control at either end of the links. If it's not possible, does anyone have any other ideas for somehow getting better bandwidth out of 500m POTS wires (quantity 4)?
