Probably not the best list to ask this and I have not yet done anything with it, but FR and frac T1's, are not that difficult and similiar to dedicated T1 setup.

Depending on how you order and what you want to do it could be something like a poor man's T1 or a stepping stone to one.  An advantage is that you are guaranteed the bandwidth you pay for, but can burst up to full T1 making it cost effective for lower bandwidth situations.

Another great thing is you can have several locations on the same FR "cloud" that share the T1.  With that let's say you have several BBS's:



      ------------  ----------
      | your POP |--| router |
      ------------  ----------
                     |    |
Full T1 to backbone  |    |
                          --------------
                          | FR cloud 1 |
                          --------------
                            |   |    |
                            |   |    |
                 Customer 1 -   |    - Customer 3
                                |
                                |
                           Customer 3



This gives you a basic idea of what you can do, but it is more complex than PTP T1 connections.  You also need to check with your local telco(s) and find out what they offer.

Livingston has some good documentation, no matter what you use or plan to use.
