Kbps - kilobits per second. KBps would be Kilobytes per second.
Mbps - megabits per second. MBps would be megabytes per second.
Gbps - gigabits per second. GBps would be Gigabytes per second.

DS = Digital Signal
OC = Optical Carrier

Note: In North America, T1 is a digital carrier for a DS1-formatted signal.
