My email was confusing since I said the word speed, I would like to ms roundtrip for the following:
*1. CPE to first layer 3 hop 2. CPE to first layer 3 upstream hop 3. CPE to layer 3 exit point of upstream

Trace route to www.yahoo.com
<http://www.yahoo.com/>1. 10.10.10.1 (CPE) 1ms 2. 10.10.10.254 (DSLAM)(cte) 21ms*(first layer 3 hop) *3. 11.1.1.1 (Router)(cte) 24ms 4. 5.5.1.3 (upstream interface)(level3) 68ms*(first layer 3 upstream hop) *5. 5.4.3.2 (exit point of upstream)(handoff from level3 to at&t) 94ms *(layer 3 exit point of upstream)
*Those ms values are what I am curious about. What are other providers seeing and what are, in your opinion, acceptable ms times for a home 1.5M dsl user...

The speeds will vary based on the packages built out. When using interleaved mode (for ADSL anyways), you will see somewhere along the lines of 20-30ms from the CPE to the DSLAM. When not using interleaved, I have seen 5-10ms between the CPE and DSLAM. Ofcourse, cable distances play into this as well I'm sure. And different technologies (SHDSL) will have different latency figures. -- Andy
