In case you haven't, you should feel free to contact Digium customer
support with installation assistance with your new card.

I think the span line above is wrong. I think you want:

span=1,1,0,esf,b8zs

The second 1 indicates that the span should recover the clock from
the remote side (which should be your provider). However, normally
when you have the timing misconfigured like this you'll get HDLC
aborts, and not just the PRI going up and down.

So before looking into any more or contacting customer support, it
might be easy to change that one line and see if the behavior is
different.
