IntraLATA vs. InterLATA Ckt Reliability

Can someone with a bit of experience in telco line engineering speak to
IntraLATA vs. InterLATA DS-1 circuit reliability?  More specifically, is
it more likely for multiple DS-1 circuits to be aggregated using a single
piece of multiplexing equipment when heading into another LATA, thus
increasing the chance of combined failure of two diverse circuits at a
single point?  I would love to have two diverse T1 circuits coming into
the offices, but it looks like they'll ultimately traverse the same telco
switches, both at the local and regional interconnection levels (? more
info ?), and it seems as though this presents increased risk.  We have
entrance failities for just one LEC in our office building here, and I
understand that a new telco buildout would require lots of investment.

I've actually talked with LEC engineers about the various switching
stations in the area, and it seems as though everything is aggregated
through a single central office before hitting the other LATAs.  Have
others encountered this same kind of topology in the past?  What are some
of the things that can be done to help ensure circuit diversity?

Lots and lots of questions, I know. ;)  Any insight into standard telco
engineering practices would be great and very much appreciated!  Tnx.
