There are only USB 1.0, USB 1.1 and USB 2.0. USB has three speed modes: - Low speed 1.5 Mbps, - Full speed 12 Mbps, and - Hi-speed 480 Mbps, this one is only in USB 2.0. Not all USB 2.0 devices are hi-speed. http://en.wikipedia.org/wiki/Universal_Serial_Bus USB 1.2 never exists. There are only USB 1.0, USB 1.1 and USB 2.0.

USB has three speed modes:
- Low speed 1.5 Mbps,
- Full speed 12 Mbps, and
- Hi-speed 480 Mbps, this one is only in USB 2.0.

Not all USB 2.0 devices are hi-speed.

ATM does not define the data rate like ISDN or T1/E1. ATM defines how to transport the data, similar to Frame Relay. Maybe 155 Mbps is the most common ATM using OC-3 (which defines the speed: 155 Mbps), but it can go up to multi-gigabit data rate (e.g. using OC-48 you get about 2 Gbps). Types and data rate of leased lines: ISDN BRI: 64 or 128 Kbps (1 or 2 B channels) + 16 Kbps (D channel) = 144 Kbps ISDN PRI T1: 1.4375 Mbps (23 B channels) + 64 Kbps (D channel) = 1.544 Mbps ISDN PRI E1: 1.875 Mbps (30 B channels) + 64 Kbps (D channel) = 2.048 Mbps E3: 34.064 Mbps T3: 44.736 Mbps OC-1: 51.84 Mbps OC-3: 155.54 Mbps OC-9: 466.56 Mbps OC-12: 622.08 Mbps OC-18: 933.12 Mbps OC-24: 1244.16 Mbps OC-36: 1866.24 Mbps OC-48: 2488.32 Mbps Broadband: ADSL download can go up to 8 Mbps actually but not very common. SDSL and HDSL emphasizes on the symmetricity(?) ranging from 1.5 to 2 Mbps. Other less common DSL types: IDSL 144 Kbps up/down, RADSL 64 Kbps - 8 Mbps down and 16 to 768 Mbps, CDSL (G.lite) 1 Mbps down and 16 - 160 Kbps up.
