Frame Relay refers to the data network that your provider uses to get data
from one endpoint to another. Inside their frame relay cloud, they usually
run ATM, but that's another matter entirely.
T-1 is a digital line that is used to access the frame relay network. so,
you have this:
Router --> CSU/DSU -----(T-1)-----(frame cloud).......
There are other options for accessing the frame cloud, but T-1 or a
fractional T-1 are the most common.
You could also have a T-1 point-to-point circuit and choose not to use frame
relay. In this case, you could use some other layer 2 encapsulation such as
HDLC or PPP. Your choice all depends on your needs and your budget.
