My old edition defines "Supertrunk" A cable that carries several video channels between facilities of a cable television company. A trunk between the master and the hub headends in a hub CATV system
"TRUNK" A communication line between two switching systems. The term switching systems typically includes equipment in a central office (the telephone Company) and PBXs. A tie trunk connects PBXs. Central office trunks connect a PBX to the switching system at the central office.
Again my dictionary is dated 1998 so I'm sure the definitions may be a little different.

Sorry I got so caught up in"super trunk" that I missed the part about "trunk".
A LINE is a connection between two phones or a phone and a switching system. (Correction: there doesn't have to be a phone at the end- it could be a fax, a modem, a whatever)
A TRUNK is a connection between two switching systems. The physical circuit could be identical to a line or it could be completely different.
In the UK they used to say (might still do) "I need to place a Trunk Call", where we would say " I need to make a Long Distance Call", because a Local call goes right to another phone (only passing through the local CO), where an LD call goes to at least one and often more, COs.
A Super Trunk, I think we can all agree, is "marketing-speak" and may mean different things in different locales.
