ok.. this is how 'conspiracy' theories are perpetuated......especially when the 
dots are connected differently or 'some' information is provided in a hand it 
down manner.... 

ATT = Many Network = Many Technolgies 
Yes on TDM network there was no such thing as 1GIG, and optics and conversions 
were very expensive. 

however as my kids say (they are in their early and mid 20's)... "... that is 
ancient......" 
For most practical purposes, the Major ILEC's have shutdown their ATM networks 
(over the last 5 year), and switched more and more of their networks over to 
Ethernet. (hint.. hint.... Ethernet over fiber has less regulations vs any kind 
of TDM) 

The 25/30% performance difference between expected and actual is most likely to 
be due to network path between the the far router he is testing with...or 
something else.... 

I would not waste too much time on hitting the carrier on the head with those 
results.. I would put traffic on it and let it fly... if you see issues with 
actual traffic levels (packet loss, or bandwidth usage tapering) then I would 
go back to the Carrier.... 

It makes no sense for any carrier today to deliver a 1gig transport, throttled 
to 700meg.... yes if it is built on a vpls/ or evpn (i.e. l2 on top of l3) then 
it is possible that there is a congested route..... either way it will be a lot 
easier for both of you and them to troubleshoot it with actual traffic (if and 
when that happens) than running iperf tests.... 

Obviously, you have to take this with a grain of salt, and YMMV.
