Gotta watch out for specifying T1 when you want Ethernet- they could just give you 4 wires on pins 1,2,4,5 :)
I see the problem as misunderstanding what "physical" actually means: 4-wire twisted pair is different from 8-wire, is different from coax, is different from SMF etc. what gets run over it is nobody's business but the person controlling the end points.
