Depends on your conditions for failure. If you are simply looking to get around hardware failures or other physical conditions which result in the T1s going down, you can use a reliable piece of ISDN gateway equipment in front of the Asterisk boxes that pushes SIP out the other end and configure it to fail over calls to a second VoIP peer. It creates a single point of failure, but one which is far, far more unlikely to fail than PC hardware.
Or, you can use a DS1-level DACS that can protection switch the T1s to another port. Ultimately, your failover options are limited if you have T1s physically going into an Asterisk box with a T1 card. Your best bet is to somehow separate the two components; then, you can get the proper redundancy measures implemented on both sides in ways that are most native and technologically appropriate, instead of coupling them in a way that makes them difficult to divest.
