That was my mistake Mike. HDSL is NOT two SDSL lines by definition. It's
just two circuits running symmetric 768k DSL (not SDSL) bonded to form a
single1.5mb line.
My fault for using SDSL (where S is the initial for symmetric) instead of
symmetric DSL lines. They are two different things in this case.
Sorry for the confusion I started, please resume your regularly scheduled
nanog ranting. :)
And thanks for the nitpicking Mike. :)
