RCA thanks for your quick reply, I'm doing a new install for a Hotel and i'm using a ADSL solution that ties into the phone lines and modulates data onto the existing voice lines, so i'm only providing data for this install, the service is from a cable modem going into the DSlam and then out into the 66 block, here's a link for the hardware i'm using, maybe this will help you understand abit more, thanks again, i'll keep nearby since i'm here already and trying to get this thing going.
