Low-speed Serial interfaces

Hey gang - I'm looking to add an older 25xx series router to my lab as a frame relay switch.

My only question is - what is a low-speed serial interface?

Anything that seems to have more than two serial interfaces usually have this in the show ver:

2 Serial network interface(s)
2 Low-speed serial(sync/async) network interface(s)

I've never seen that before - I'm guessing that will still work for FR, but I'm just curious what it means.

THX
