As an aside: T1, T2 and so on are some type of American designation. What do they mean?
In Sweden, there is no special terminology for capacity. Lines are simply rated in Mbit/s. E.g a DSL line to your home will get you .25-10Mb/s, whereas university lines are 1-2.5 GB/s. (The national network is 10 GB/s)

EU+World: E1 ~ 2.0mbit/s E3 ~ 32mbit/s Same OC lines.
Home use: DSL can be symmetrical or asymmetrical sym is usually small business class, running from 192kbit-2.0kbit/s, asymmetrical is normally residential with anywhere from 256kbit-3mbit downloads, and 128kbit-1.5mbit uploads. There are other types like HDSL (phone companies use this to run T1 lines), IDSL (144kbit symmetrical for long distances), and VDSL (very high speed, not common in the US, but around in some places worldwide).
Cable can run between 10mbit download to 2mbit upload, and will depend on provider, network, and service plan.
Token ring (being phased out) = 4 or 16mbit/s per ring Ethernet 10mbit/s, runs on cat3 wiring Ethernet 100mbit/s, runs on cat5 wiring Ethernet 1000mbit/s, runs on cat5e + wiring (highly reccomended cat6). All ethernet has ~100meter length limit over copper, and does come in fiber forms (multimode, singlemode) that can range up to 20+kilometers !.
