The confusion of a "T3" and what many are using if for is clearly an issue here. A major issue is that there is no clean solution between T1 and T3 without co-location (and thats a scam, becaue a 10Mb/s ethernet is not really 10Mb/s in the same way that a serial line is). Many are going to fiber and using either a clocked down line, which is a great solution because you can use what you need and upgrade immediately upon notifying your provider, metered T3, which is more dangerous (unless you buy our bandwidth manager! :-) ) and also creates conflicts if there is disagreement on the rate, and others (like UUNET) provide a full T3 through a cascade FR switch with a low CIR, which is a scary service because it gives UUNET the control of whether or not your packets get thrown away by the switch...and gives them the opportunity to oversell their bandwidth in a dangerous way. It is not "penny-wise and pound foolish" to not want to spend $60,000. if your requirements are only 4, 6 or 8Mb/s, which is the case with many small and medium size ISPs. You should not need that equipment (and it shouldnt cost what it does), but there are high performance solutions at these speeds that will save you big money and not compromise your needs.
