> There are some problems with what you're trying to accomplish here. In our SLAs for aDSL/sDSL that we give to our subscribers, speed is measured from the DSLAM in the telco CO to the end users router - at least this is where the speed guarantee is.
And that is the speed you can read from the CPE.
> Anything past the DSLAM and you're data is on the CLEC or ILEC ATM network (i.e. Covad, Verizon) to get the data to your ISP.
ATM circuits can have parameters. The incumbent doesn't do it,
but there are CLECs that have set up bandwidth parameters.
> Also note that ADSL speeds are always sold as "up to".
Not with the CLECs here :) Here it is always sold as guaranteed
DSL sync speed (except for the 8 Mbps lines, they are quaranteed
at 2 or 4 Mbps). If I am more then 3 km away from the CO, I can't
get a 2 Mbps line because they can't guarantee the ATM sync speed.
> We've been dealing with CLEC and ILEC ADSL for 6 years and I've never seen a guarantee of speed given at the max advertised speed for ADSL.
Not for the 8 Mbps lines, but I can get a 2 Mbps 1:1
oversubscribed line which means that the speed is guaranteed on
the DSL line, on the ATM network and on the network of the ISP.
