Getting totally OT

Thanks for the clarification but I am still not clear.

So what is a DS1 then?  Is the usage of the term DS1 synonymous with T1?

It would seem if someone is speaking of T1s then they should also use
T3, if they are speaking of DS1 then DS3 would be the proper naming
convention.

Thanks,
