bps = bits per second
kbps = 1000 bps
Mbps = 1000 kbps
Gbps = 1000 Mbps

DS-X: X refers to the PDH (Plesiochronous Digital Hierachy) Level (ANSI)
T-X: X refers to the North American PDH Carrier Level
E-X: X refers to the European PDH Carrier Level (ITU-T)
J-X: X refers to the Japanese PDH Carrier Level

A T-1, J-1, E-1 is considered a DS-1. When Calculating the speeds of a PDH carrier, the rate listed is often faster than if you calculated it directly, this is because extra synchronization, framing and control bits are added so that lower levels can be multiplexed into a higher level.

OC-X: X refers to the Optical Carrier Level, from North American SONET (ANSI)
STS-X: X refers to the Electrical Carrier Level, from North American SONET (ANSI)
STM-X: X refers to the International SDH (Synchronous Digital Hierachy) Level (ITU-T)

OC-X and STS-X speeds are identical, OC is optical, STS is electrical signaling.

* ATM doesn't really define the physical layer, the majority of what the ATM specifications hold is independent of the physical layer and the speed at which it runs. ATM is usually thought of as being carried over another protocol. These values listed are the most commonly used values.
