Chuck, The question posed by Chris, "how long is your access line"?, is a rather important data point before answering your question. I have a T3 that is about 15 miles long. It runs between two 7500 routers. Its minimum ping round trip time with 100 byte pings is 2 ms. It is not very heavily loaded with peaks of about 10 Mb/s today and the max round trip time was 21 ms. So that should give you some minimal bounds of what you might expect. As the saying goes your mileage may vary. Speed of light does play in here, if the circuit is longer. Also intervening electronics such as a frame cloud or telco muxes also add latency. Walt
