My understanding is that you can save a lot on access charges by bypassing
the LEC.

Now, I'm not in marketing, so I don't know what AT&T actually offers
to our customers.  I do know that it's technically possible to connect
a suitably equipped PBX (or anything else that speaks Q.931, I think)
right up to a 4E.

I've heard that the customer can either provide the connection to the 4E
or can contract with a LEC or whatever they want.
