It's a bit esoteric. I'm working on something that will help clarify. In short, a DS3 is a frame structure (28 T1s plus 1.504 mbps overhead, all interleaved in a certain way, etc, etc). A T3 is an actual interface (certain peak-to-peak voltage, certain impedance, etc). It's rare that you would ever get your hands on an actual DS3 because that is created by, say, a T3 mux. T1s as input, DS3 frame created from those, and T3 out for further transmission. In that example, there’s never a discrete DS3 out in the open - it exists only inside the mux and only briefly. To (hopefully) further clarify, you won't find a SONET box with a DS3 interface. It'll have a T3 interface. They're pretty much used interchangeably in industry though. > > scott > > ""Nate"" wrote in message > news:[EMAIL PROTECTED] > > We've run a bandwidth test on our DS3 with nothing connected > to it but a > > workstation (and obviously a router/pix).
