What is the difference between being on-call and being on stand-by?

If you are on “stand-by” outside of your regular working hours, it means you need to be available to work and cannot use the time that you are in that status for your own purposes. You receive your regular straight time wages for the whole time that you are on stand-by status.

If you are “on-call” outside of your regular working time, it means you must be available to work, but unless you have to work, you are not subject to any restrictions on the use of your time. If you are on “on-call” you receive one-sixth of your straight time pay (if you are an hourly employee).
