How much further than 300m? It might be very well possible to just lower the speed to 10M and just use that If you already have some quality Cat5 cable between both points it's worth a shot. I support some sites with this arrangement and I've had to find 10M hubs for replacement hardware (the

yes, more than 300 meters (longer than copper based ethernet allows). Yes to E1, as I understand it, it's just a config change on many cards anyway. I'm specificly looking at pci based t1/e1 cards because I'm finding single port cards on ebay going for 100-200 usd. in some cases I may want to

T1 is NOT DSL. Most T1 links you purchase now are brought into your building with a type of DSL conversion to extend the distance between repeaters/amplifiers. T1 is purely a digital signal. DSL converts the ones and zeros to audio(multiple tones to provide multi channels of data). A
