It is completely dependent on what kind of traffic you're running across 
the lines.  That said, the last time I looked at the numbers on the 
RBOCs, they were generally oversubscribed 8-12:1.

I'll also note that if you have 1 line, you probably can't oversubscribe 
it 8:1.  If you have 1 PRI, you may be able to.  If you have 100 PRIs, 
the odds get better.

Of course, if you're selling to call centers, the ratios aren't nearly 
as good.
