Adtran 908e SIP to PRI

Is there any way to configure the PRI to go Out Of Service(Drop the D Channel) if the SIp circuit goes OOS or the router loses communication with the SIP Host?

My PBX never shows the PRI going out of service so when the circuit goes out we cannot fail over to our backup POTS lines

Thanks

JP
