When you purchase a DS1, you're purchasing 1.5Mb/s. That means, 1.5Mb/s in BOTH directions. If the circuit was supposed to be billed as 3Mb/s, they would claim 3Mb/s linerate. Ethernet, ATM, blah blah blah works the same way. ADSL and cable modems are the strange mediums that are not SYMETRIC. IMHO, 1Mb/s means 1Mb/s IN, OUT or BOTH. --- John Fraizer EnterZone, Inc On Thu, 19 Apr 2001, Martin Hannigan wrote: > > > Isn't in+out a more fair representation of usage?
