<div dir="ltr">I'm not clear on your topology, but the Adtran solution is a regular 1Gig switch with ActivReach capability. At the other end it's a dongle that converts back to regular ethernet. If you can put the switch in the middle it can service multiple sites so it might be cost effective. It also has a lot of advantages over any other kind of cat-3, or DSL aggregation. It's symmetric; full speed in both directions. Not a hack. And you can manage it just like any network switch so you can apply VLANs, QOS, etc. It's the only product like it in the market.<div><br></div><div>For anyone on this list that may need to deal with buildings where new wiring is a problem (asbestos is a typical example), this is a solution for utilizing existing "telephone" wiring to build a network.<br><div><br></div><div><br></div><div>If you are looking for carrier grade, then Adtran also makes DSLAMs with Gig over copper DSL type solutions, but I assume you are looking for cheap.<br><div><br></div><div><br></div><div><br></div><div>Regards,</div><div><br></div><div>John</div><div><br></div></div></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Sep 29, 2015 at 2:33 PM, Trevor Cordes <span dir="ltr"><<a href="mailto:trevor@tecnopolis.ca" target="_blank">trevor@tecnopolis.ca</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><span class="">On 2015-09-29 A Myriad of MUUGers wrote:<br>

</span>Yes, we fully control both ends, and can put a box at both. Compression<br>
could possibly help in our scenario too, as the traffic might be<br>
repetitive.<br>

</span>Options that don't require replacing the DLSAM might be feasible if the<br>
cost isn't too high. VDSL looks like a possibility.<br>

<br>
</span>That sounds promising too.<br>

<br>
</span>We might do wireless. But the line of sight isn't great, and weather<br>
might be a concern? However, the application on top of all of this<br>
maintains one constant all-day TCP connection that can't tolerate being<br>
broken at all, and IME wireless is a lot less reliable than wires, even<br>
POTS wires.<br>

<br>
</span>Yes, we control the whole thing, including the copper. I need to find<br>
out exactly what cable is in there now to make sure it's CAT3.<br>
<br>
We actually have 3 or 4 POTS runs to the 500m out location, and the<br>
DSLAM capacity is already there, and we have DSL modems too (so that's<br>
all "free"), so possibly trying a software-on-linux-boxen approach<br>
first would be worthwhile.<br>
<br>
Many of the products y'all pointed out are really neat too, but if we<br>
need multiples of them it might start getting pricey, and from what I<br>
can tell would still require linux-boxen to aggregate.<br>
<br>
Thanks for all the tips! MUUG shines once again. I'll keep you<br>
posted. I may have further questions as I implement. Maybe I'll do a<br>
presentation on it down the road (if it works out!).<br>
