Since K56flex and x2 performance varies widely, modem connect speed tests were conducted by dialing from two test sites into three Philadelphia-area regional ISPs: NetReach (www.netreach.net), which supports K56flex, SNiP (www.snip.net), which supports x2, and FastNet (www.fast.net), which offers both K56flex and x2 at all dial locations. Connect speeds in Kbps were derived from modem logs after repeatedly dialing into local numbers from each test site. For comparison, the same remote FastNet POP was dialed from both sites (one number for x2, another for K56flex).
