Chris -
UI stands for Unit Interval - it's one data bit regardless of data rate.
For example, at a data rate of 2048 kbit/s, one UI is equivalent to 488 ns,
whereas at a data rate of 155.52 Mbit/s, one UI is equivalent to 6.4 ns.
You should find this in many of the LAN textbooks - the link below takes you
to a summary article which has a first cut coverage of jitter, wander, etc.
