Hi, my name is Kieren, and I have ISDN.
"Hi, Kieren"
I have seen both sides of this. I live in a rural area that receives very poor connect quality (24,000bps) on a v.90 modem (behind too many repeaters to get faster v.90 performance). I had access to 4 different ISP's that all gave the same results- lag.
I switched to ISDN and have seen much better results. To me, the improved speed reduces the amount that I have to "guess", that is, it lessens the amount I have to compensate for net lag. Planes are much closer to where I believe they are than in the past.
I still see nights where things lag a bit, and have nights where I disconnect frequently, but as has been posted, that is a function of DoS, not my ISDN.
Will cable help (assuming I can ever get it)? I'm betting it will.
