How about writing a script that detects the lack of connectivity with the 
PBX using a command like:

 	/usr/sbin/asterisk -r -x 'dahdi show status'

and parsing the output. If the 'error' condition exists, then execute 
commands like:

 	/etc/init.d/asterisk stop
 	/etc/init.d/dahdi stop
 	/etc/init.d/dahdi start
 	/etc/init.d/asterisk start

and then schedule the script to execute (via cron) every x minutes. The 
exact command to show the status of your connection and whether the dahdi 
restart is needed will be up to you to figure out.
