Is it possible to have two cisco routers at one site (configured with
HSRP) each with a T1 access circuit to a single carrier's frame network
to provide failover between the two circuits. Assume the remote site
is configured the same with four PVC's in the clouds between each frame
port like a bowtie.

Yes, but hsrp is just mostly so that the default gateway on the lan is
maintained in light of a router failure. All hosts where the two
routers are point to the hsrp address as their default gateway. You
will also need to run a dynamic routing protocol for the routers (eigrp,
ospf, etc..). Also, you need to request engineering documents from the
telcos (frame and local loop providers). If you aren't careful, you
will still be relying on one frame switch, one binder group, and one
physical path into your building. End result several single points of
failure that will still take both links down. For example a car hits
the telephone pole and destroys the 50 pair run into your building, both
links are down. This solution may still provide you with enough
redundancy to be attractive, but don't oversell it to yourself or the
higher ups.

Paul and Buzz - thanks for the input.

Cisco has also introduced a new feature called Global Load Balancing
Protocol (GLBP) that will load balance outbound traffic over both WAN
links.

Think of it as HSRP+
