<div dir="ltr">Here's a couple of distances I'm looking to cover (distances are +- 10%):<br><br>1 at 400M<br>1 at 600M<br>1 at 1800M<br>1 at 2400M<br><br>some of these links may already have pots circuits complete with occasional ringing voltage in the same conduit (but likely not the same cable). how far can I push the distance of E1 over copper using only 2 cards back to back?<br>

How much further than 300m? It might be very well possible to just<br>
lower the speed to 10M and just use that.... If you already have some<br>
quality Cat5 cable between both points it's worth a shot. I support<br>
some sites with this arrangement and I've had to find 10M hubs for<br>
replacement hardware (the previous guy insisted that only a particular<br>
model HP print server would work, coincidently that model only has a<br>
10M Ethernet port)... it's not something I would advise someone to<br>
setup but if cost is a concern I wouldn't rule it out -- it certainly<br>
can work and be reliable in the real world.<br>
