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.
